The earthquake is not only a destruction of buildings, but also a shattering of people's mental states. How survivors regulate dysfunctional feelings and thoughts toward death in the aftermath of an earthquake is a matter of curiosity. Therefore, this study examined the role of hope, psychological inflexibility, and psychache, which will provide a better understanding of people's obsession with death after the earthquake in Turkey. Participants were 419 Turkish individuals aged 18–59 years from 61 cities in Turkey. Structural equation modeling was performed. The findings showed the full mediation model that psychological inflexibility and psychache had significant mediating roles in the relationship between hope and death obsession, respectively. Whether directly or indirectly, increased hope is associated with less psychological inflexibility and less psychache among earthquake survivors. Positive and healing potentials of hope and psychological flexibility in reducing obsession with death in individuals with earthquakes or other traumatic experiences have been revealed.

This qualitative study, in which the phenomenon of “being affected by an earthquake as a traumatic experience” was examined in order to contribute to the management of risk situations that may arise in possible disasters, was conducted with a interpretive/phenomenological design. The data were obtained by interviewing adults who experienced the earthquake in Kahramanmaraş (Turkey) on February 6, 2023. A semi-structured interview questions including psychological interpretation steps was used. The data obtained from the interviews were visualized using MAXQDA software and contributed to making them more understandable for the reader. Most of the participants explained the earthquake with the metaphor of “apocalypse”. It was understood that they explained the moment of the earthquake as “humming and explosion sounds”, “death” and “collapse of the building” and showed reactions such as “being under the rubble”, “helplessness”, “shock” and “praying”. In the adaptation process after the earthquake, it was observed that they felt the “need to make sense” and resorted to “social support repertoire” to cope. This study on post-earthquake reactions emphasized the individual and social effects of the earthquake.

An AI-driven approach to extract interrelationships between disasters
IF 4.2 1区 地球科学 Q1 GEOSCIENCES, MULTIDISCIPLINARY Pub Date : 2025-03-19 DOI: 10.1016/j.ijdrr.2025.105417

Accurately identifying interrelationships between disasters is essential for comprehensive multi-disaster risk assessment. Traditional manual methods rely heavily on expert judgment, which may lead to overlooked or inconsistently documented disaster interrelationships. To address this challenge, this study develops an AI-driven approach to automatically extract disaster interrelationships from large-scale textual data using a fine-tuned Universal Information Extraction model. First, disaster interrelationships are systematically categorized into six distinct types, considering both disaster causation and impact perspectives. Secondly, a large-scale dataset is constructed by collecting 5212 Chinese-language disaster-related paper abstracts from the China National Knowledge Infrastructure (CNKI). Among them, 267 abstracts were manually annotated to train and evaluate the model. Thirdly, the fine-tuned model is applied to the remaining 4945 abstracts to extract large-scale disaster relationship triplets, with manual validation conducted for less common triplets to ensure result reliability. Finally, disaster interrelationships are visualized using complex network graphs and matrices, providing an intuitive representation of multi-disaster interrelationships. The key contribution of this research is the development of an AI-driven approach to systematically extract disaster interrelationships from large-scale datasets, improving the accuracy and scalability of identifying disaster interrelationships. Furthermore, this study establishes a comprehensive and updatable database of disaster interrelationships, addressing limitations in previous research, such as incomplete data coverage and limited exploration of relationship types, and helps scholars to identify disaster interrelationships that may have been previously overlooked.

Critical node failure, impact and recovery strategy for metro network under extreme flooding in Shanghai
IF 4.2 1区 地球科学 Q1 GEOSCIENCES, MULTIDISCIPLINARY Pub Date : 2025-03-18 DOI: 10.1016/j.ijdrr.2025.105414

Extreme flooding can inundate critical nodes in urban metro network, triggering system failures. However, comprehensive indicators for identifying critical nodes and assessing network impacts under disruptions remain underdeveloped. Research also largely relies on hypothetical disruptions rather than flood events with specific intensities and spatial extents. This study replicates the “7·20” extreme rainstorm that occurred in Zhengzhou and applies it to Shanghai through a numerical flood simulation. Using Shanghai's weighted metro network, which includes stations, lines and passenger flow, we employ a complex network method to identify critical nodes and simulate the impact of their failure due to flooding on network functionality. Finally, we discuss the recovery priorities for failed nodes in terms of network functionality. Our results indicate that 54 stations, comprising 14.2 % of the total, may experience water inflow and failure. Stations with high centrality scores, primarily located within the city's inner ring, are particularly prone to flooding. Successive station failures lead to a loss of 1.6 %–76.5 % in the network efficiency (NE) and 0.7 %–82.7 % in the giant connected component (GCC). When the number of failed stations reaches 13, network functionality experiences a dramatic loss of approximately 50 %. Compared to the greedy algorithm (GA), the criticality-based approach is less efficient in restoring network functionality but more computationally feasible. By incorporating flood scenarios and weighted indicators, our approach offers more context-driven and practical insights. Our study provides a methodology for the rapid assessment of critical node exposure, functional impact, and optimal recovery strategies for metro network based on various scenarios.

Assessing the interrelationship between monsoon flood disasters and major crop production in Bangladesh
IF 4.2 1区 地球科学 Q1 GEOSCIENCES, MULTIDISCIPLINARY Pub Date : 2025-03-18 DOI: 10.1016/j.ijdrr.2025.105401

Bangladesh faces various acute and chronic natural calamities due to its precarious global positioning. Floods are among Bangladesh's leading and most frequent disasters. While much research has been published on the association between flood risk and agricultural losses, significant gaps exist in recognizing the relationship between monsoon flood disasters and agrarian land and production losses. This study aims to investigate the substantial crop losses brought on by monsoon floods, with a particular emphasis on the impacts of floods on crop productivity and strategies to mitigate those effects. It also describes the FAO method for assessing flood damage to the agricultural sector, concentrating mainly on flood damage to rice and jute crops. Both qualitative and quantitative methodologies were employed to collect and analyze the data for this study. Primary data was collected through interviews, structured questionnaires, personal observations, and informal discussions with 250 respondents. Secondary data was obtained from official records such as libraries, journals, yearly reports, statistics yearbooks, newspapers, and other relevant sources.
The combined quantitative and qualitative data revealed that flooding interrupts crop-growing patterns (rice, potato, pepper, and maize), decreases cropping land area, reduces crop production, and affects socio-economic conditions overall. In addition, this study focuses on the barriers and constraints that could obviate flood management. Hence, floods cause production losses of about 2.25 metric tons of rice and 2 metric tons of jute, equivalent to more than 50,000 ($600) and 45,000 ($550) BDT, individually. The study further recommended a monsoon flood management approach that prioritizes resilience and infrastructure development through constant surveillance and evaluation to ensure regional food security utilizing sustainable crop production. The crop damage assessment method described in this paper can also be applied in other areas for flood risk management.
孟加拉国由于其岌岌可危的全球定位,面临着各种急性和慢性自然灾害。洪水是孟加拉国最主要、最频繁的灾害之一。虽然关于洪水风险与农业损失之间关系的研究成果已经发表了很多,但在认识季风洪水灾害与耕地和生产损失之间的关系方面还存在很大差距。本研究旨在调查季风洪灾给农作物带来的巨大损失,特别强调洪灾对农作物生产力的影响以及减轻这些影响的策略。研究还介绍了粮农组织评估洪水对农业部门造成的损失的方法,主要集中于洪水对水稻和黄麻作物造成的损失。本研究采用了定性和定量两种方法来收集和分析数据。原始数据是通过访谈、结构化问卷、个人观察以及与 250 名受访者进行非正式讨论收集的。综合定量和定性数据显示,洪水中断了作物种植模式(水稻、马铃薯、辣椒和玉米),减少了种植面积,降低了作物产量,并影响了整体社会经济状况。此外,本研究还重点探讨了可避免洪灾管理的障碍和制约因素。因此,洪水造成的产量损失约为 2.25 公吨大米和 2 公吨黄麻,分别相当于 50,000 多美元(600 元)和 45,000 多美元(550 元)。研究还建议采取季风洪灾管理方法,通过持续监测和评估,优先考虑抗灾能力和基础设施发展,以确保利用可持续作物生产实现地区粮食安全。本文所述的作物损害评估方法也可用于其他地区的洪水风险管理。

Evolving disaster resilience in the Philippines: Insights from the 2021 and 2023 World Risk Poll on socio-economic, regional, and systemic factors
IF 4.2 1区 地球科学 Q1 GEOSCIENCES, MULTIDISCIPLINARY Pub Date : 2025-03-18 DOI: 10.1016/j.ijdrr.2025.105415

The Philippines is consistently one of the world's most at-risk countries due to its location within the Pacific Ring of Fire and the “typhoon belt”. However, resilience at national and regional levels remains understudied, particularly in relation to socio-economic inequalities, gender dynamics, and governance. This study addresses this gap by analyzing resilience trends from the 2021 and 2023 World Risk Poll (WRP) Philippines dataset, focusing on the influence of gender, urbanicity, and income across individuals, households, communities, and society, using statistical and data analysis tools. Results reveal a general decline in scores, with sharp drops in Region 4B (MIMAROPA–highest resilience) and Region 7 (Central Visayas–mid-range). Conversely, Region 13 (Caraga–lowest) and Region 5 (Bicol–mid-range) improved, reflecting the success of community-based disaster risk reduction initiatives and governance. Gender disparities narrowed, with women scoring higher in household and societal resilience, while men excelled in community resilience. Urbanicity showed no significant association, although urban areas had higher individual and household resilience, while rural areas demonstrated stronger societal resilience. Income disparities persisted, with higher-income groups consistently achieving greater resilience, particularly at individual and household levels, due to better access to resources and opportunities. These findings emphasize the need for targeted, evidence-based strategies to build resilience in vulnerable regions in the Philippines, informing inclusive policies, equitable resource distribution, and governance collaboration. While the WRP provides valuable insights, reliance on self-reported perceptions highlights the need for further mixed method and longitudinal studies. Lessons from the Philippines thus offer globally relevant strategies for building resilience in disaster-prone regions.

Flood vulnerability of rural women – An indicator-based approach
IF 4.2 1区 地球科学 Q1 GEOSCIENCES, MULTIDISCIPLINARY Pub Date : 2025-03-17 DOI: 10.1016/j.ijdrr.2025.105404

In Kerala, floods are considered as a major and most frequent hazard affecting about 14.8 % of the area and 52 % of the population being vulnerable to flood impacts. There are large differences between men and women in terms of impacts, vulnerabilities, and capacity to adapt to these challenges. Rural women are hard hit by the flood impacts especially due to constraining gender norms and high dependence on agriculture. Hence, the study aims to assess the Flood Vulnerability Index of Rural Women (FVIRW) for the selected Agro-ecological Units (AEUs) of Kerala, using the three dimensions of vulnerability viz, Adaptive capacity, Sensitivity and Exposure, under which 9 major components and 69 indicators were selected. The study was conducted in Pokkali Land and Kuttanadu AEU and was based on the primary data collected from 200 rural women through personal interviews. The developed FVIRW value indicated that rural women in both Pokkali Land (0.562) and Kuttanadu (0.551) are highly vulnerable. Probing into the dimensional values showed that Pokkali Land, had higher index value (0.679) for exposure followed by sensitivity dimension (0.671) and adaptive capacity (0.471). In case of Kuttanadu, the exposure dimension had higher value (0.687) followed by sensitivity (0.640) and adaptive capacity (0.464) dimension. In depth analysis in to the components like socio-demographic profile, livelihood strategies, socio-economic assets, water, health, and food indicated the need of urgent interventions at policy level. Hence to improve the current situation, adaptive interventions like schemes to improve the credit borrowing capacity of the women, linking women organizations to credit cooperative institutions, and mitigation interventions like conducting trainings on flood risk management and technology adoption, and insurance on assets loss can be implemented. The FVIRW developed can also be extended to other prominent flood vulnerable tracts of Kerala and other places with necessary modification.

Scale-dependent exposure bias: Assessing disaster risk in less economically developed regions
IF 4.2 1区 地球科学 Q1 GEOSCIENCES, MULTIDISCIPLINARY Pub Date : 2025-03-17 DOI: 10.1016/j.ijdrr.2025.105406

Natural hazards disproportionately affect different regions and social demographics, leading to spatial inequality in disaster exposure. Current assessments of spatial inequality in disaster risks are shaped by the identification of hazard-bearing bodies and risk zoning methods, which are heavily influenced by scale selection and classification approaches. This study investigates the effects of these factors on identifying vulnerable populations in Less Economically Developed Regions(LEDRs), analyzing the correlation between LEDRs exposure and multiple natural hazards, including earthquakes, floods, landslides, and droughts, across provincial, urban-rural, and municipal scales. Using spatial analysis techniques, the exposure of LEDRs to individual hazards and the integrated disaster risk of Sichuan Province was calculated. The vulnerability of impoverished populations in hazard-prone areas is quantified using the Less Economically Developed Regions Exposure Bias (LEDR-EB) index. The findings indicate that: (1) Different risk classification methods significantly influence the delineation of high-risk zones, particularly for impoverished populations; (2) The LEDR-EB index varies across spatial scales. At broader scales (provincial and urban-rural levels), the exposure bias is not uniform, with urban LEDRs exhibiting a 0.24 higher compared to rural areas, indicating greater disaster exposure for impoverished urban populations. At the municipal scale, the variation in the LEDR-EB index is more obvious and shows a significant influence from the risk classification levels. This study contributes to understanding the critical role of spatial scale and hazard risk zoning in assessing disaster exposure in LEDRs, providing insights necessary for the development of equitable disaster risk reduction policies aimed at mitigating vulnerability among impoverished populations.

Tsunami evacuation risk change associated with urban recovery in Banda Aceh after 2004 Aceh tsunami
IF 4.2 1区 地球科学 Q1 GEOSCIENCES, MULTIDISCIPLINARY Pub Date : 2025-03-15 DOI: 10.1016/j.ijdrr.2025.105400

Twenty years after the 2004 Aceh tsunami, Banda Aceh has undergone significant urban recovery, including the development of tsunami evacuation infrastructure. However, shifts in population distribution and evacuation capacity necessitate a reassessment of tsunami evacuation risk. This study evaluates the extent to which the “Build Back Better” strategy has been realized in terms of tsunami evacuation risk reduction, considering long-term population changes and the expansion of evacuation facilities. Using WorldPop Hub data (2000–2020), we analyzed demographic changes within tsunami risk zones in Banda Aceh. While the highest-risk zone (R3) experienced a population reduction to three-quarters of its previous level, the risk-free zone (R0) saw a 6.9 percentage point increase, suggesting relocation from high-risk coastal areas. However, nearly 29 % of Banda Aceh’s population still resides in high-risk zones, highlighting persistent vulnerabilities. To assess evacuation feasibility, we conducted network-based tsunami evacuation simulations in Meuraxa, the most at-risk district, under three scenarios: (A) horizontal evacuation only, (B) using existing tsunami evacuation buildings (TEBs), and (C) using both TEBs and nearby facilities. The evacuation failure rates within the 35-min tsunami arrival time were 84.5 %, 3.1 %, and 1.1 %, respectively, indicating the remaining risks despite recovery efforts. While TEBs reduced evacuation times by over 30 min, facility capacity remained imbalanced, with some exceeding capacity tenfold. These findings highlight the need for improved evacuation facility placement and capacity to enhance future tsunami resilience.

A coastal risk analysis for the outermost small islands of Indonesia: A multiple natural hazards approach
IF 4.2 1区 地球科学 Q1 GEOSCIENCES, MULTIDISCIPLINARY Pub Date : 2025-03-14 DOI: 10.1016/j.ijdrr.2025.105377

Coastal risk analysis is important for the sustainable development and resilience of small islands. Even though there is an increasing effort to develop risk analysis at the global scale, the integration of multi-hazard, exposure, and vulnerability for outermost small islands is still rare. This study is the first to address the coastal risk on the outermost small islands of Indonesia, located at the country's territorial edge. The methodology quantifies hazard, exposure, and vulnerability variables, and collating the indices into a risk matrix. The results identify the full range of risk levels on outermost small islands represented in the island dataset, providing different approaches of addressing adaptation based on island's risk variables. Rote is identified with a Very High-risk level, while Makalehi has the highest hazard index, Bintan the highest exposure index, and Letti-Kisar the highest vulnerability index. Both coastal and geophysical hazards significantly influence risk, while economic land use impacts exposure. Infrastructure, including connectivity access and protection structures, plays a crucial role in vulnerability. The factors identified in this study, such as the highest hazard potentials, the most exposed variables, or the greatest vulnerability factors, could be used to craft policy recommendation that are designed and implemented to create island-specific adaptation strategies. In general, this study addresses a gap in current research, serving as a foundation for further investigation into coastal risk assessment. This study provides critical insights into the compounded risks faced by similarly outermost regions, offering transferable lessons for other developing archipelagic countries in enhancing their resilience.
