    Abstract This study investigates compound flooding on the Fugeshi River (Noto Peninsula, Japan) in the aftermath of the January 2024 Noto Peninsula earthquake (M7.6). The authors aimed to quantify the impacts of ground deformation on flooding, while integrating the historical evolution of the floodplain and potential climate change effects by simulating sea-level rise. The method is based on the analysis of aerial photographs (1947–2024), pre/post-earthquake LiDAR data, rainfall records (1944–2024), and 2D hydraulic modeling to identify flood vulnerability points from the LiDAR-derived DEMs pre- and post-earthquake. The main findings are that: (1) Rainfall intensity increased by 0.132 mm/year since 1944, with events > 14 mm/h rising by 1.4% over 70 years; (2) earthquake-induced ground deformation (1–3 m uplift) created new flooding patterns at the transition between artificially straightened downstream reaches and meandering upstream sections; (3) river modifications (1947–1965) established uneven flood protection, with smaller stopbanks upstream creating vulnerability points. In conclusion, the convergence of climate change–induced rainfall intensification, seismic ground deformation, and river engineering legacy effects amplifies flood hazards in coastal regions, highlighting the need for integrated multi-hazard flood management approaches.

    This study investigates co-seismic landslides triggered by the 1 January 2024 Mw 7.6 Noto Peninsula earthquake in Japan using LiDAR differentiation and a modified Savage–Hutter model. By analyzing pre- and post-earthquake high-resolution topographic data from 13 landslides in a geologically homogeneous area of the peninsula, we characterized distinct landslide morphologies and dynamic behaviours. Our approach combined static morphological analysis from LiDAR data with simulations of granular flow mechanics to evaluate landslide mobility. Results revealed two distinct landslide types: those with clear erosion-deposition zonation and complex landslides with discontinuous topographic changes. Landslide dimensions followed power-law relationships (H = 7.51L0.50, R2 = 0.765), while simulations demonstrated that internal deformation capability (represented by the μ parameter) significantly influenced runout distances for landslides terminating on low-angle surfaces but had minimal impact on slope-confined movements. These findings highlight the importance of integrating both static topographic parameters and dynamic flow mechanics when assessing co-seismic landslide hazards, particularly for predicting potential runout distances on gentle slopes where human settlements are often located. Our methodology provides a framework for improved landslide susceptibility assessment and disaster risk reduction in seismically active regions.

    ABSTRACT This study assessed stakeholders' perceptions of current methods and technologies for monitoring and controlling fisheries activities in Namibia's Exclusive Economic Zone (EEZ). The research was prompted by reports of illegal fishing and inadequate resources for effective oversight. Understanding stakeholders' views is crucial for policymakers to develop suitable monitoring approaches. A qualitative investigation was conducted using in‐depth interviews (18 participants) and three focus group discussions (22 participants). Findings revealed that men dominate Namibia's fisheries industry. Air surveillance and sea patrols are the primary monitoring measures, supplemented by Vessel Monitoring System (VMS) and Automatic Identification System (AIS) technologies. About 32.5% of participants were fisheries inspectors, observers, and researchers with 11–15 years of experience. Most participants rated current methods and technologies as good: 72.5% for sea patrols, 65% for air surveillance and 80% for technologies. Despite positive ratings, several challenges were identified: lack of resources and funding, inadequate modern infrastructure, high maintenance costs, limited stakeholder cooperation and compliance issues. These findings underscore the need for improvements in vessel documentation and authorization, monitoring methods and the adoption of advanced technologies like drones and onboard cameras. The study highlighted the importance of enhancing regional cooperation and coordination to address the challenges posed by globalization, and to realize the state's sovereignty and territorialization, with the EEZ still being a contested space.

    The Pacitan Regency is at risk of megathrust earthquakes and tsunamis due to the seismic gap along the southern region of Java Island, making risk-reduction efforts crucial. This research aims to analyse the tsunami risk associated with a potential megathrust earthquake scenario in Pacitan’s coastal areas and develop sustainable mitigation strategies. The research employs spatial analysis to evaluate the risk and subsequently formulate strategies for long-term mitigation. A weighted overlay method was utilised to integrate hazard (H) and vulnerability (V) datasets to produce a tsunami risk map (R). The hazard component was modelled using a tsunami propagation simulation based on the Shallow Water Equations in the Delft3D-Flow software, incorporating an earthquake scenario of Mw 8.8 and H-loss calculations in ArcGIS Pro 10.3. The vulnerability assessment was conducted by overlaying population density, land use, and building footprint from the Global Human Settlement Layer (GHSL) datasets. Finally, sustainable strategies were proposed to mitigate the tsunami risk effectively. The results show that Pacitan faces significant tsunami disaster risk, with tsunami waves at the coast reaching 16.6 m. Because the coast of Pacitan is densely populated, mitigation strategies are necessary, and in the present contribution, the authors developed holistic spatial planning, which prioritise the preservation and restoration of natural barriers, such as mangroves and coastal forests.

    Drone-mounted LiDAR systems have revolutionized forest mapping, but data quality is often compromised by occlusions caused by vegetation and terrain features. This study presents a novel framework for analyzing and predicting LiDAR occlusion patterns in forested environments, combining the geometric reconstruction of flight paths with the statistical modeling of ground visibility. Using field data collected at Unzen Volcano, Japan, we first developed an algorithm to retrieve drone flight paths from timestamped pointclouds, enabling post-processing optimization, even when original flight data are unavailable. We then created a mathematical model to quantify the shadow effects from obstacles and implemented Monte Carlo simulations to optimize flight parameters for different forest stand characteristics. The results demonstrate that lower-altitude flights (40 m) with narrow scanning angles achieve the highest ground visibility (81%) but require more flight paths, while higher-altitude flights with wider scanning angles offer efficient coverage (47% visibility) with single flight paths. For a forest stand with 250 trees per 25 hectares (heights 5–15 m), statistical analysis showed that scanning angles above 90 degrees consistently delivered 46–47% ground visibility, regardless of the flight height. This research provides quantitative guidance for optimizing drone LiDAR surveys in forested environments, though future work is needed to incorporate canopy complexity and seasonal variations.

    On the first day of 2024, a strong Mw.7.6 earthquake followed by a tsunami shook the Noto Peninsula (Japan) located on the coast facing the Sea of Japan. It resulted in numerous casualties, infrastructures and dwelling destroyed. The earthquake also triggered an estimated 5,000 coastal and mountain co-seismic mass-movements, from which 930 were identified by aerial photographs and digitized from the emergency aerial photographs (2/1/2024). The goal has been to provide a preliminary assessment of their distribution and characteristics. The medium surface of the landslides was found to be 1,749 m2, with numerous small < 50 m2 landslides and at least one large deep-seated landslide (0.8 km × 1 km). The mountain landslides were concentrated around two clusters, which were not close to the epicentre, but around 7 km and 10 km from the epicentre. From a disaster-risk perspective, the 1/1/2024 Noto Peninsula earthquake is typical of a ‘coastal earthquake’ where the coastal landslides, even sparse collapsed on the main artery of the peninsula, the ring road, isolating communities and hampering the disaster relief process.

    Purpose The ineffectiveness of flood control in climate-impacted majority-world cities like Jakarta highlights the need for policies that integrate local knowledge and embrace water harmony rather than resistance. This study explores flood adaptation in North Jakarta's kampungs (urban informal settlements), aiming to enhance the efficacy of current flood disaster management. The outcomes of the participatory planning mechanism simulation that we propose are expected to provide valuable insights for the urban planning approach in that city. Design/methodology/approach We employed focus groups and design charrettes with a bottom-up approach to explore how local knowledge can enhance spatial flood management and urban planning policies. In total, 17 diverse participants, covering various ages and professions, engaged in these activities. Our methods aimed to be culturally sensitive and inclusive, embracing indigenous values like musyawarah and gotong royong. The research methodically examined flood implications and adaptations in informal settlements, progressing through preliminary understanding, data triangulation, and a reflective synthesis of the findings. Findings Amid worsening global changes like sea level rise, community-focussed, collaborative planning can help create tailored flood-resilience solutions. The research reveals that partnerships between communities and organisations promote city-wide, flood-adapted environments, aligning policy with the needs and goals of those most affected by flooding. This collaboration enhances flood disaster management and planning policies. Research limitations/implications This research focusses on Jakarta's flood adaptation and urban planning, reflecting on historical situations relevant to urbanising majority-world countries. Whilst specific to Jakarta, it offers perspectives on managing global environmental challenges such as sea level rise. Subsequent research should prudently consider each locale's distinct geographic and social milieu and the trust in planning systems in applying these findings, methodologies and approaches. Originality/value This study clarifies the relationship between disaster management, policy and flood adaptation, focussing on local knowledge in North Jakarta, pertinent to urbanising majority-world nations. Jakarta's historical and modern dynamics, including globalisation, reveal specific prospects and obstacles to applying vernacular knowledge to planning and disaster response. It highlights crucial points for policymakers in the majority of the world to address growing flood risks and create strategies that integrate local and traditional wisdom.

    Abstract River ecosystem services (RES) are vulnerable to landscape changes mainly by volcanic eruptions. Therefore, this study aims to assess RES in the volcanic area which was affected by the major and minor eruptions of Mount Merapi, Indonesia. The RES referred to the regulating and supporting services of the Krasak River in Jogjakarta. The research involved collecting water and biodiversity samples from two distinct Merapi’s hazard zones (KRB I and KRB II) along the river. Parameters related to regulating services, such as particulate, organic, and nutrient purification, biological control, as well as supporting services like primary productivity, were quantified. We conducted an analysis to understand how landscape conditions interacted with these parameters and employed the t-test to assess differences in RES between the two KRBs. Our findings revealed that the Krasak River exhibited a range of values, including 2.40–5.95 mg/l for Biological Oxygen Demand (BOD), 0.61–3.41 mg/l for nitrate, 0.02–0.11 mg/l for phosphate, 160–60,000 MPN/100 ml for coliform, and 156.3–937 µg/l for chlorophyll-A. These values demonstrated the river’s capacity to perform both regulation and support services. However, certain segments showed variations in ecosystem services, possibly due to the presence of autochthonous matter from aquatic organisms and decomposing organic matters. This showed that volcanic eruption and landscape are closely linked with the water quality and aquatic biodiversity, which affect the ecosystem services.

    Abstract On 13th August 2021 at Unzen Volcano (Japan), an 81 mm.hr-1 peak-rainfall (1486 mm in 2 weeks) triggered series of erosion and deposition features in the Tansandani and the Gokurakudani gullies, all adding up to 57,800 m3 of erosion and 39,600 m3 of deposition. Upstream of the Sabo dam located at the exit of the Tansandani Gully, a large deposit has been visually identified as a potential debris-flow front candidate. However, the absence of direct observation leaves some uncertainty on the process that deposited the material and the magnitude of the flow. In the present contribution, the authors are investigating (1) the role of the debris-flow body in constructing the deposit and (2) the role of the tail of the debris-flow in eroding the fresh deposit. To reach this objective, the authors have combined a field investigation with direct observation, UAV (Unmanned Aerial Vehicle) LiDAR (Light Detection And Ranging) and Photogrammetry, and GIS (Geographic Information System) analysis of the field data. From this data, a 2D hydrodynamic simulation and sediment transport models were applied. The results show that the debris-flow ran beyond the first Sabo dam, with part of the material trapped on both sides of the gully. Afterwards, a central channel connected to sub-channels conveyed the diluted flow, most probably < 25 cm with maximum velocities between 4 to 5 m.s-1 at peak flow. Only the debris-flow phase went over the internal shoulders of the Sabo dam. A lobe occupies the top half of the study area and its deposition has been discussed to be related to the sudden widening of the gully, while the lower half is connected to the base-level created by the check dam.

    Abstract As climate change creeps into the 21st century, the intensity of debris flows due to heavy and concentrated rainfall has increased in mountainous regions of Japan and East Asia. However, the relationship between climate change and an increase in debris flows is likely to be non-linear. Rainwater infiltrates more quickly into porous material, and the lack of vegetation cover increases evaporation and the temperature of surface sediments. In addition, periodic gully collapses bring fresh layers of porous material that increase the distance between the surface and the vadose zone. Therefore, to understand the relationship between volcanic debris flows (or lahars), parameters such as density, porosity, temperature, and moisture retention must be captured in detail in both time and space. The aim of this paper is to assess the role of loose, coarse, and porous sediments in lahar triggering. The present study was conducted at Unzen volcano in the Tansandani Guly between 31 May and 1 June 2023, 30 years after the last eruption. The dacite material is composed of a matrix of sand and coarse sand mixed with larger fractions and blocks, therefore traditional density measurement methods could not be applied, and a photogrammetric based method was used. In the field, sets of SfM-MVS photographs were taken before and after digging a hole in the sediments so that the measured mass could be compared to the volume of the hole in the sediments. After the sediments were dried, the dry and wet density, bulk density and porosity of the sample were calculated. When compared to the temperature data collected in the field, the following results were obtained: (1) The porosity of the volcanic material was highest in the lower reaches, followed by the upper reaches, and lowest in the middle reaches. This may be because fine sand washed out of the upstream area by rainfall is currently stored in the midstream area, which may facilitate debris flow generation. In addition, the downstream area has a high porosity, which may be due to the surrounding vegetation preventing the influx of new fine sand from the channel wall. (2) Because of the higher porosity and the lack of organic matter and vegetation cover, the increase in temperature acts more directly on the decrease in water content than in mountainous areas. Consequently, empirical equations for the potential for mudslides in volcanic areas with respect to surface temperature and soil moisture need to be developed for hazard and disaster risk management purposes.

    In this article, desertification and dune progression over vegetation was quantified using remote sensing data. However, vegetation buried under sand blowout could not be counted using this method. Therefore, to estimate the extent of buried vegetation, a GPR campaign was conducted over the coastal sand-dune of Tottori Prefecture (Japan) in combination with a high-resolution topographic UAV-based survey of the topography. The results show that buried vegetation exists underneath sand-blowout, especially near the dune ridges, and can extend from 20 to 30 meters further than the estimate based on airborne remote sensing. Furthermore, the presence of palaeo-vegetation in palaeodune layers also provides the information on the long-term evolution of sand dunes, which can be used to reconstruct Quaternary coastal environments.

    On 5–6 July 2017, an unstable atmospheric condition caused an unusual concentration of rainfall above the Northern part of Kyushu Island, triggering a set of hydro-meteorological hazards. Within the affected area, the mountainous subwatershed of the Akatani River was significantly impacted by numerous landslides combined with debris flow and floods. National and local agencies deployed a plan of reconstruction to restore the floodplain and protect inhabitants. Regarding the hydrosystem in the Akatani watershed, this reconstruction project mainly focuses on the restoration of damaged protection systems and the construction of new infrastructures. Thus, this paper aims to explain the restoration plan of the Akatani River in terms of the strategic Japanese River System Sabo and then as a model of a national-scale spatial plan. It draws on (i) a literature review based on the historical evolution of Japanese protection systems and the River Sabo System; (ii) field surveys in 2019, 2022 and 2023, in conjunction with (iii) interviews with local, regional, and national officials; and (iv) a Geographical Information System analysis of previously and newly built protection systems through aerial photograph interpretation and geospatial data. Sabo works implemented in the Akatani watershed illustrate the engineering vision of Japanese river management. They also constitute a comprehensive system and include a downstream–upstream logic which echoes that of the River System Sabo. In addition, the disaster of July 2017 and the government’s response emphasize the continuous adaptation and improvement of the Japanese disaster management system, which mitigates severe disasters.

    The study introduces a theory about an Evander-size impact on the surface of Dione. Our study suspects a relatively low-velocity (≤5 km/s) collision between a ca. 50–80 km diameter object and Dione, which might have resulted in the resurfacing of one of the satellite’s intermediate cratered terrains in various ways, such as surface planing by “plowing” by ricocheting ejectiles, ejecta blanket covering, partial melting, and impact-triggered diapir formation associated with cryotectonism and effusive cryo-slurry outflows. Modeling the parameters of an impact of such a size and mapping the potential secondary crater distribution in the target location may function as the first test of plausibility to reveal the location of such a collision, which may be hidden by younger impact marks formed during, e.g., the Antenor, Dido, Romulus, and Remus collision events. The source of the impactor might have been Saturn-specific planetocentric debris, a unique impactor population suspected in the Saturnian system. Other possible candidates are asteroid(s) appearing during the outer Solar System’s heavy bombardment period, or a collision, which might have happened during the “giant impact phase” in the early Saturnian system.

    Land use/cover (LU/LC) classification provides proxies of the natural and social processes related to urban development, providing stakeholders with crucial information. Remotely sensed images combined with supervised classification are common to define land use, but high-performance classifiers remain difficult to achieve, due to the presence of model hyperparameters. Conventional approaches rely on manual adjustment, which is time consuming and often unsatisfying. Therefore, the goal of this study has been to optimize the parameters of the support vector machine (SVM) algorithm for the generation of land use/cover maps from Sentinel-2 satellite imagery in selected humid and arid (three study sites each) climatic regions of Iran. For supervised SVM classification, we optimized two important parameters (gamma in kernel function and penalty parameter) of the LU/LC classification. Using the radial basis function (RBF) of the SVM classification method, we examined seven values for both parameters ranging from 0.001 to 1000. For both climate types, the penalty parameters (PP) showed a direct relationship with overall accuracy (OA). Statistical results confirmed that in humid study regions, LU/LC maps produced with a penalty parameter >100 were more accurate. However, for regions with arid climates, LU/LC maps with a penalty parameter >0.1 were more accurate. Mapping accuracy for both climate types was sensitive to the penalty parameter. In contrast, variations of the gamma values in the kernel function had no effect on the accuracy of the LU/LC maps in either of the climate zones. These new findings on SVM image classification are directly applicable to LU/LC for planning and environmental and natural resource management.

    Internal temperature variations of pyroclastic flows and their deposits are arguably the most challenging data to acquire. As a preliminary study of the temperature variation inside pyroclastic flows, the remains of Onokoba Elementary School (Shimabara, Japan) were investigated. The elementary school is located in the close vicinity of Unzen volcano and was hit by one of the largest pyroclastic flows during the latest active period of the volcano on 15th of September 1991. This present preliminary study aims to determine the temperature exposure of various portion of the school building using field-forensic and urban geology. Natural hazard methods applied to the damaged materials exposed to high temperature have generated a temperature fingerprint the maximum temperature distribution. Charred wooden parts and plastic gutters installed on the schoolyard-side faced of the building turns out to be the most useful temperature indicators. The various deformation and alterations of the studied materials show significant differences in the temperature exposed to. Such differences on the second-floor section (between 75-110°C and 120-150°C) and on the first-floor section (above 435-557°C) of the building do not simply imply significant temperature heterogeneity in short distance (some ten to ≤100 m) inside the pyroclastic flow, but also points toward the possible effects of the building architecture on some key dynamic parameter of the pyroclastic flow. Such information may be important for planning future hazard mitigation actions.

    The pre-colonial history (i.e. before the 16th century) of Tonga and West Polynesia still suffers from major gaps despite significant scientific advances in recent years, particularly in the field of archaeology. By the 14th century, the powerful Tu’i Tonga kingdom united the islands of the Tongan archipelago under a centralised authority and, according to tradition, extended its influence to neighbouring island groups in the Central Pacific. However, some periods of deep crisis were identified, e.g. in the mid- 15th century, marked by an abrupt cessation of inter-archipelago migration on the deep seas in the Pacific, significant cultural changes, and a decrease in accessible natural resources. The origins of these disturbances are still debated, and they are usually assigned to internal political problems or loss of external influence vis-à-vis neighboring chiefdoms. However, the hypothesis of a major natural disaster was rarely suggested up to now, while field evidence points to the occurrence of a very large tsunami in the past, including the presence of numerous megablocks that were deposited by a “red wave” (or peau kula, which also mean tsunami in the Tongan language) according to a local myth. Drawing on a body of new evidence from sedimentary signatures and radiocarbon dating of charcoal and marine bioclasts, geomorphology, and sedimentology, in support of previously published archaeological data, we argue that a large tsunami inundated large areas of Tongatapu island in the mid-15th century with runup heights up to 30 m, and that the Tu’i Tonga kingdom was severely impacted by this event. We also discuss the likely sources of this tsunami.

    In the aftermath of pyroclastic density current-dominated eruptions, lahars are the main geomorphic agent, but at the decadal scale, different sets of processes take place in the volcanic sediment cascade. At Unzen volcano, in the Gokurakudani gully, we investigated the geomorphologic evolution and how the topographic change and the sediment change over time is controlling this transition. For this purpose, a combination of LiDAR data, aerial photography and photogrammetry, ground penetrating radar and sediment grain size analysis was done. The results show choking zones and zones of enlargement of the gully, partly controlled by pre-eruption topography, but also by the overlapping patterns of the pyroclastic flow deposits of 1990–1995. The ground penetrating radar revealed that on top of the typical lahar structure at the bottom of the gully, side wall collapses were trapping finer sandy sediments formed in a relatively low-energy deposition environment. This shows that secondary processes are taking place in the sediment transport process, on top of lahar activity, but also that these temporary dams may be a source of sudden sediment and water release, leading to lahars. Finally, the sediments from the gully walls are being preferentially oozed out of the pyroclastic flow deposit, meaning that over longer period of time, there may be a lack of fines, increasing permeability and reducing internal pore pressure needed for lahar triggering. It also poses the important question of how much of a past event one can understand from outcrops in coarse heterometric material, as the deposit structure can remain, even after losing part of its fine material.

    In recent years, heavy rainfall leading to floods, landslides and debris-flow hazards have had increasing impacts on communities in Japan, because of climate change and structural immobilism in a changing and ageing society. Decreasing rural population lowers the human vulnerability in mountains, but hazards can still leave the mountain to the plains and sea, potentially carrying drifted-wood. The aim of the paper is to measure the distribution of wood-debris deposits created by the 2017 Asakura disaster and to rethink the distribution and spatial extension of associated disaster-risk zoning. For this purpose, the authors: (1) digitized and measured the distribution of drifted-wood, (2) statistically analyzed its distribution and (3) calculated the potential impact force of individual drifted timber as a minimal value. The results have shown that there is a shortening of the wood debris as they travel downstream and that the geomorphology has an important control over deposition zones. The result of momentum calculation for different stems’ length show spatially differentiated hazard-zones, which limit different disaster-risk potentials. From the present finding, we can state that we (1) need to develop separate strategies for sediments and wood debris (2) and for wood hazards, zonations can be generated depending on the location and the size of the deposited trees that differs spatially in a watershed.

  • 空撮とSfMを用いたアクセス困難地の3Dモデリング
    OBANAWA H, HAYAKAWA Y, GOMEZ C
    In hardly accessible areas, aerial photogrammetry and laser scanning with manned flight are normally used for topographic measurement. However, those methods are expensive and therefore frequent measurement is practically difficult. To solve such problem, the authors have experimented an aerial photography based SfM (Structure from Motion) technique on a 'peninsular-rock' surrounded on three sides by the sea at a Pacific coast in Chiba Prefecture. The research was carried out using UAS (Unmanned Aerial System) combined with a commercial small UAV (Unmanned Aerial Vehicle) carrying a compact camera. The 3D model has been constructed by digital photogrammetry using a commercial SfM software which can generate sparse and dense point-clouds, from which polygonal models and orthophotographs can be calculated. Using the 'flight-log' and/or GCPs (Ground Control Points), the software can generate digital surface model. As a result, high-resolution aerial orthophotographs and a 3D model were obtained. The results have shown that it was possible to survey the sea cliff and the wave cut-bench, which are unobservable from land side. This system has several merits: firstly lower cost than the existing measuring methods such as manned-flight survey and aerial laser scanning. Secondly, compared to these other methods, the one the authors have presented also enables frequent measurements. Thirdly lightweight and compact system realizes higher applicability to various fields.

  • Disaster Risk
    Irasema Alcantara Ayala, Christopher Gomez, Ksenia Chmutina, Dewald van Niekerk, Emmanuel Raju, Victor Marchezini, Jake Rom Cadag, J C Galliard
    共著, 2022年05月, 150, 英語, The text offers a comprehensive and unique perspective on disaster risk associated with natural hazards. It covers a wide range of topics, reflecting the most recent debates but also older and pioneering discussions in the academic field of disaster studies as well as in the policy and practical areas of disaster risk reduction. Disaster Risk offers a uniquely flexible teaching resource through its innovative structure. It emphasises two main reading pathways, the first focuses on the interactions between the human and natural dimensions of disasters and constitutes the conventional and linear structure of the book, which includes five main sections including the nature and impact of disasters; people’s vulnerabilities and capacities; natural hazards; people’s response to and resilience after disasters; and disaster risk reduction and management. The second pathway cuts across the previous sections and addresses transversal issues. These streams look at such as natural hazards, vulnerability and capacities as well as cross-cutting issues such as gender, age and health. An associated website provides links to additional material and teaching and learning activities. The four authors have extensive experience in the field of disaster studies and provide a wide range of expertise covering both the social and physical dimensions of disasters. In addition, they have a large experience as practitioners of disaster risk reduction and management and have extensively dealt with policy makers over the past two decades. This book will be of particular interest to undergraduate students studying geography and environmental studies/science. It will also be of relevant to students/professionals from a wide range of social and physical science disciplines, including public health and public policy, sociology, anthropology, political science and geology., ISBN: 9781315469614

  • Spatial distribution of radon and thoron in the soil around active faults as a contribution to the elevated indoor radon
    Janik Miroslaw, 小平 聡, ゴメス クリストファー
    日本学術振興会, 科学研究費助成事業 基盤研究(C), 基盤研究(C), 国立研究開発法人量子科学技術研究開発機構, 2021年04月01日 - 2024年03月31日
    The sudden and catastrophic or slow and continuous surface release of naturally occurring toxic gases, such as radon or CO2, poses a serious health risk to people living in geologically active regions. Indoor radon activity concentrations, however, vary widely and depend on a variety of factors such as underlying geology, water, weather conditions, and building type. In this project, we seek to understand and estimate radon transport in soil in a region with active faults. The results of this project will 1) help find solutions to mitigate the problem of radon exposure and 2) can be used to apply radon to geohazard studies. The configuration and validation of the radon and thoron measurement system at the reference point (QST) was completed this year. We developed a new device, called PECAME, for simultaneous measurement of permeability, CO2 and CH4. The PECAME consists of pressure and flow meters, pumps, and sensors to measure CO2 and CH4. Data are collected and stored in memory every one minute using a data logger (GRAPHTEC midi Logger GL220). The PECAME device was tested at a reference site located at the QST campus, and the permeability measurement results were compared with the commercial portable permeability measurement device RADON-JOK. The operating principle of PECAME and RADON-JOK is based on Darcy's law, which describes the flow of fluid through a porous medium. In addition, subsurface surveys were conducted to identify faults near the active Fugendake volcano (Nagasaki Prefecture) using ground penetrating radar (GRP) and data sets were collected.

  • 地形発達学的手法と種々のセンシング技術を応用した深層崩壊発生危険度評価手法の開発
    山川 陽祐, 堀田 紀文, ゴメス クリストファー, 鄒 青穎, 正岡 直也
    日本学術振興会, 科学研究費助成事業 基盤研究(B), 基盤研究(B), 筑波大学, 2019年04月01日 - 2023年03月31日
    本研究は，深層崩壊の実用的な発生危険度評価手法の開発を目指す。深層崩壊は発生頻度が低いものの現象・被害の規模が大きいため，より的確な発生予測が求められる。しかし，崩壊に先立つ予兆が隠微で予測が困難であるため，潜在的な危険個所の段階的な絞り込みがより着実と考えられる。本研究では，既存の地形指標によって抽出された危険個所に対して，地形発達学的手法（谷の下刻発達の評価）および種々のセンシング技術を適用し，地盤内部構造を踏まえた安定性の低い斜面を検出する手法の開発に取り組む。具体的には，深層崩壊の主要な発生場である大起伏の付加体堆積岩山地において，①直接手法を用いた斜面安定性の評価，②物理探査手法およびUAVリモートセンシングの適用性検証，③地形発達学的手法の適用性検証，に取り組む。当該年度においては，①に関して，崩壊トリガーとなる地下水位の降雨応答特性の解明のために，主に静岡県の大井川水系（井川湖周辺）において多地点での水文観測（平水時の流量および渓流水の電気電導度の計測）を実施した。その他，滋賀県の葛川水系（比良山）や台湾の中央山脈南部においても同様の観測を一部行った。②に関しては，葛川水系（比良山）にて比抵抗探査法と自然電位法の適用性の検証を行った。また，台湾の中央山脈南部においても比抵抗探査法の適用性検証を行った。③については，大井川水系（井川湖周辺），葛川水系（比良山），台湾の中央山脈南部においてそれぞれ航空レーザー測量により取得された高精細な数値地形図に基づき，深層崩壊に先立つと考えられる重力変形地形などの判読を行った。

  • 分布型水土流出モデルの長期解析に基づく流木被害軽減のための森林管理手法の検討

    日本学術振興会, 科学研究費助成事業 基盤研究(A), 基盤研究(A), 東京大学, 2018年04月01日 - 2022年03月31日
    流木被害を受けた複数の対象地を含む森林流域において，土砂と流木の生産，輸送，堆積メカニズムに関する現地調査と，各種の土砂移動モデルの適用と検証を行った．崩壊に起因する土石流は細粒分の液相化により流動特性が著しく変化するため，崩壊後の土砂の堆積範囲の正確な予測が流木対策においても重要である．また，各支流域の地形条件が土石流および洪水に伴って流下する流木量に影響した．長期的な土砂と流木の動態評価の結果から，斜面と河道システムの連結を考慮することで流木被害の軽減に繋がる森林のゾーニングが可能であると考えられた．

研究シーズ

■ 研究シーズ
  • 気候変動に伴う森林斜面豪雨災害
    シーズカテゴリ：社会基盤（土木・建築・防災）, 環境・農学, 自然科学一般
    研究キーワード：気候変動, 土砂災害, 里山, 大雨
    研究の背景と目的：この研究では、現場での土質調査および領域気候モデルと土質力学モデルを用いて、長崎県の雲仙火山、長野県の焼岳火山、愛知県の瀬戸町と神戸市の周辺地域の豪雨災害、特に土石流や流木災害の発生に対する、日本周辺海域の水温変化の寄与を調査する。この結果は、気候変動に対する当地域の脆弱性を示すとともに、今後、我々の持続可能な生活を実現可能とする地域基盤システムを構築するための知見となると考える。
    研究内容：気候変動は人間社会と自然システムの双方へ影響を与え得るが、このように多圏にまたがるような複雑な相互作用システムは、まだ完全には理解されていない。本研究プロジェクトでは、、従来、個々に扱われていた、海洋、大気、土質力の異なる地球圏を統合化するアプローチにより、地球規模の気候変動が地域社会へ与える影響と脆弱性の評価を行う点が革新的である。このような複雑なシステムの理解のために、近年、“Critical Zone”(Richardson, 2017)と呼ばれる新たな研究分野がアメリカBoulder Colorado大学する国際プロジェクトとして開始されており、本プロジェクトは、この新しい科学分野の一端を担うことも期待できる。
    期待される効果や応用分野：本研究が提案する、「気候変動による局所的豪雨メカニズムの変容と地域基盤システムの脆弱性の評価」は、気候変動に適応する地域社会構築に対する新しい知見を生み出すものと考えている。海に囲まれた日本は、海洋を介して急激な気候変動を経験しており、また今後も避けることはできない。本プロジェクトで得られた知見は、“Critical Zone”のような国際的な研究コミュニティへの貢献に繋がることが期待できる。
