In this paper, we propose a workable definition of good practice by applying the ‘min-max strategy of concept formation’. We analyse a representative sample of international organisations' DRM publications on good practices, as well as good practice definitions from various academic disciplines, to establish the minimal and maximal boundaries of the concept as it can be applied in DRM. We argue that a workable definition of good practice should be situated within these boundaries and that the following elements should be included: i) practices take a holistic approach to one or more DRM cycle phases; ii) practices are effective, efficient, equitable and inclusive; iii) the evaluation process of such practices should be transparent and based on sufficient and sound evidence and clear evaluation criteria; iv) when the dissemination advocates replication of the practices, contextual factors should be considered.</div></div>","PeriodicalId":13915,"journal":{"name":"International journal of disaster risk reduction","volume":"130 ","pages":"Article 105834"},"PeriodicalIF":4.5,"publicationDate":"2025-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145156193","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A novel concept of Impact Percentiles is introduced using the Index of Multiple Deprivation (IMD), comparing localised deprivation scores against national averages and maxima to quantify relative multi-dimensional vulnerabilities. Assessing relative multi-dimensional vulnerability is superior because it contextualises vulnerability by enabling comparisons across regions or populations, making it more useful for prioritisation, policy decisions, and resource allocation. The analysis reveals acute deprivation across six Lower Layer Super Output Areas (LSOAs) in Kingston upon Hull and estimates relative disadvantage. Critical data-driven insight is provided into the intersection of physical flood exposure and socio-economic sensitivity.

One of the key components in managing tsunami risks lies in understanding its intensities. Understanding potential intensity in correlation with tsunami's characteristics and the vulnerability of at-risk elements are essential for an effective tsunami risk management. This study proposes an eight-grade tsunami intensity scale centered on identifying potential damage to coastal buildings. A Building Vulnerability Index (BVI) which is utilized to determine vulnerability levels of coastal buildings was refined through an expert opinion survey. Additionally, field data from three major tsunami events, each triggered by different mechanisms, provided empirical data for the construction of the scale. Ordinal regression analysis was conducted on the sampled buildings to link inundation depths and damage states across four building vulnerability classes. Results from the analysis provide evidence that more vulnerable buildings reach substantial damage states at lower inundation depths compared to more resilient buildings. Following this, a tsunami intensity scale with eight discrete grades was constructed to offer a simple yet robust tool that is intended to streamline this approach for local stakeholders, particularly where complex data or assessment technique remains inaccessible or unfeasible. The study concluded that the proposed scale can be further refined as more post-tsunami survey data particularly from different regions and source events become available. In addition to refining the BVI formulation, tsunami induced currents, or other hydrodynamic drivers can be integrated in future iterations to move towards an integrated tsunami intensity framework.</div></div>","PeriodicalId":13915,"journal":{"name":"International journal of disaster risk reduction","volume":"130 ","pages":"Article 105826"},"PeriodicalIF":4.5,"publicationDate":"2025-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145156183","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These strategies differ in the level of information sharing during initial treatments, and decisions on resource allocation and patient transportation. A general resilience metric was adapted to fit the healthcare context and used to evaluate the collaborative care strategies in various disaster scenarios (mild, moderate, and severe). In our experimental setting, the new collaborative care strategy consistently enhanced resilience, facilitating a quicker return to the pre-disaster state compared to the other two approaches. In contrast, the semi-collaborative care strategy demonstrated worse resilience in nearly all scenarios, although it outperformed the non-collaborative care when dealing with a small number of patients.

CART analysis identified smaller organizational scale and lower risk perception as key predictors of BCP absence: specifically, fewer clients, fewer full-time equivalent (FTE) nurses, and lack of experience with natural hazard-induced disasters (NHIDs). Logistic regression confirmed that fewer FTE nurses were significantly associated with BCP absence (OR = 0.87, 95 % CI 0.78–0.97; p = 0.02). To promote universal implementation, targeted support is needed for small-scale VNSs and for enhancing risk perception.

This is particularly concerning in coastal urban areas, where the complexity of urban flood dynamics is exacerbated by their exposure to coastal, fluvial, and pluvial flooding. To address such challenge, we characterize flood risks to CIs in Philadelphia based on property-level simulations of flood events over a 35-year period (1985–2019) using an integrated coastal-hydrologic-hydrodynamic modeling approach. The characterizations of CI flood risks consider multiple perspectives, including the relative distributions of flood exposures, hazards, risks to various CI types by different flood drivers, assessments of individual and aggregated flood damages, and geospatial patterns of CI flood risks in relation to flood-related variables. Additionally, a scenario analysis examines indirect and cascading disruptions of interconnected infrastructure caused by flood-induced power outages at substations. Our analysis identifies frequent, localized damages associated with fluvial flood events as well as severe, extensive damages from compound coastal-fluvial-pluvial flood events. Notably, commercial and industrial CI facilities are particularly susceptible to floods due to their concentrations across low-lying areas. Furthermore, our study presents an approach that, for the first time, utilizes concentration curves for infrastructure, to enhance flood management planning by prioritizing flood mitigation measures tailored to identified flood risk characteristics. Overall, the CI risk characterizations for past flood events provide a foundational understanding that can inform targeted allocations of limited resources towards risk-based investments in flood management and establish a baseline for future risk assessments.</div></div>","PeriodicalId":13915,"journal":{"name":"International journal of disaster risk reduction","volume":"130 ","pages":"Article 105825"},"PeriodicalIF":4.5,"publicationDate":"2025-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145156181","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
