However, relevant research on the use of staged evacuation in wildfire evacuation planning for such WUI communities is still scarce. This study aims to utilize predefined evacuation zones (PEZs) and the Multi-Agent Transport Simulation (MATSim) package to develop and test a new staged wildfire evacuation model for WUI communities with transient populations. Our proposed model uses different types of data (e.g., residential parcels, household vehicle ownership, second-home occupancy rates, Genasys zones, and OpenStreetMap roads) as inputs and can derive evacuation time estimates (ETEs), traffic counts on the road links, and individual travel times as outputs. We used the Tahoe Donner community in Truckee, California to demonstrate the effectiveness of the model. The results show that staged evacuation can significantly reduce traffic congestion near the fire front compared to simultaneous evacuation. Our model can help incident commanders gain a better understanding of how to use PEZs in wildfire evacuation to create more effective community evacuation plans.</div></div>","PeriodicalId":13915,"journal":{"name":"International journal of disaster risk reduction","volume":"126 ","pages":"Article 105625"},"PeriodicalIF":4.2,"publicationDate":"2025-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144231124","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 selected, designed buildings were subjected to bidirectional seismic excitation using 22 ground motion records for nonlinear dynamic analysis. The seismic risk of SF, SB, SBSB, and FL buildings is evaluated using probabilistic seismic demand models, seismic fragility functions, seismic drift hazard curves, mean annual exceedance probabilities, and collapse margin ratio (CMR). Results demonstrate that the seismic risk of SB and SBSB typologies is similar and less than that of the SF and FL buildings. From the CMR, the study found that the application of seismic provisions in the Indian standards resulted in satisfactory, safe seismic performance of the sloping ground buildings at the 10 % and 2 % probability of exceedance in 50 years. Further, sloping ground buildings typically have coupled structural irregularities (both plan and vertical), characterizing their seismic behaviour. Numerous descriptors exist in the literature for assessing the level of seismic irregularity in irregular buildings, including sloping ground buildings, based on their geometry or fundamental dynamic properties. In the final part, the paper evaluates the applicability and efficacy of existing irregularity descriptors in quantifying the seismic risk of sloping ground buildings by correlating the seismic risk to the irregularity descriptors. It is found that the existing descriptors are poorly correlated with the seismic risk of sloping ground buildings.</div></div>","PeriodicalId":13915,"journal":{"name":"International journal of disaster risk reduction","volume":"126 ","pages":"Article 105614"},"PeriodicalIF":4.2,"publicationDate":"2025-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144190220","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}

The study showed that experience was the most influential factor in shaping perceptions, indicating that individuals directly involved in installing the sensors were more likely to appreciate their benefits. This study emphasizes the importance of more targeted educational campaign efforts that emphasize the role and importance of earthquake sensors in reducing earthquake risk and bridging the gap in public understanding of earthquake sensors.

The integration of InSAR and numerical modelling provided complementary and more detailed information compared to the isolated use of each approach. The InSAR analysis offered an overview of surface deformations, allowing for large-scale monitoring of movements, and its limitation in providing complete three-dimensional information was addressed by the numerical modelling, which enabled the decomposition of movements along the main direction of the landslide, precisely identifying the movement trajectory. The results showed predominant movements in the transverse direction, with a less significant vertical component, consistent with the observed kinematics. InSAR data allowed for the comparison of numerical modelling estimates with real observations, enhancing the consistency of the simulations. These data revealed significant movements upstream of the bridge, confirming the critical areas identified by modelling, which compensated for the lack of satellite data downstream, showing intense displacements. The modelling also highlighted significant displacements in the bridge’s structural elements, with downstream tilting caused by the horizontal thrust of the landslide. The integrated approach offered a clearer understanding of landslide dynamics and their impact on infrastructure, offering a valuable tool for monitoring and risk management in vulnerable areas.</div></div>","PeriodicalId":13915,"journal":{"name":"International journal of disaster risk reduction","volume":"126 ","pages":"Article 105568"},"PeriodicalIF":4.2,"publicationDate":"2025-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144212153","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}

This study investigates the function of language in early warning systems and analyses options for improving disaster communication to guarantee clarity, accessibility, and cultural relevance at Walmer Airport Valley, with a particular emphasis on the efficacy of multilingual communication. A quantitative survey was administered to 300 participants from the Xhosa-speaking community in Walmer Airport Valley from 5 July to August 25, 2024. Descriptive and inferential statistics, encompassing chi-square tests, regression analysis, and ANOVA, were employed to examine the correlations among demographics, trust in communication channels, and message clarity. The research indicated that 90 % of participants comprehended disaster concepts; however, only 85.4 % encountered early warning messages. Although 86 % of individuals own mobile phones, only 30 % received early warnings through this medium. Community radio was the most reliable medium, with a trust level of 88 %. The relationship between message clarity and education level was strong, with a Chi-square value of 96.282 (p &lt; 0.001). In contrast, the relationship between the work position and trust in communication demonstrated an even stronger correlation with a Chi-square value of 114.527 (p &lt; 0.001). The regression analysis showed that message clarity powerfully affected message efficacy since the regression coefficient was 0.489 (p &lt; 0.001). These research outcomes show that disaster communication needs clear, organised messaging that suits cultural variations and a better mobile network infrastructure to maximise its success rate. The research delivers crucial findings regarding how to combine customised communications with language-based accessibility services to reduce disaster risks.

This study targeted three tsunami-prone villages in the Sirimau District, collecting data through interviews, questionnaires, and field surveys conducted from May 27 to 31, 2024. The findings revealed that general tsunami knowledge scored at a \"Ready\" level, while emergency planning reached a \"Very Ready\" level. Despite strong scores, key gaps persist. These include limited historical disaster knowledge, difficulties in estimating tsunami arrival times, and challenges in integrating emergency plans with community-based preparedness measures. Among the studied villages, Galala demonstrated the highest level of readiness, while Pandan Kasturi exhibited the lowest due to limited knowledge retention and infrastructural issues. These disparities underscore the importance of improving tsunami awareness and preserving the historical memory of past disasters. Actively involving communities in evacuation drills and simulations is crucial, as hands-on participation enhances their understanding of escape routes and emergency responses. Moreover, public-private partnerships can play a pivotal role by initiating community-wide campaigns, promoting tsunami awareness, and installing clear evacuation signs to improve preparedness. Using a data-driven approach, this research offers valuable insights into the link between tsunami knowledge and emergency preparedness.
