Background/Objectives: Non-Communicable Diseases (NCDs) place an excessive strain on health systems in disaster-affected settings and may lead to a parallel public health emergency lasting months or years after a disaster. Although NCDs are increasingly recognized as a major challenge in disasters and humanitarian emergencies, a dedicated and standardized response plan is missing, as well as a shortage of evidence-based guidelines for NCD management in theses contexts. Over the years, Emergency Medical Teams (EMTs) have traditionally been deployed to manage acute conditions such as trauma and infectious diseases that quickly impact health systems. However, greater attention is needed to address acute exacerbation of NCDs and to ensure continuity of care for people with chronic health needs in disasters and emergencies. Methods: We conducted a scoping review exploring the EMTs’ management of chronic NCDs during disasters and humanitarian emergencies, in order to identify the strategies adopted, the challenges faced, and the recommendations provided to address this health problem. The online databases PubMed, Scopus, and EBSCO were searched to identify relevant papers. Results: After screening the papers against the eligibility criteria, 17 publications were retrieved. Five different areas of intervention concerning EMTs and NCDs management were identified: (i) EMTs pre-departure preparation, operational time, and length of stay; (ii) EMTs staff composition and training; (iii) EMTs logistics; (iv) EMTs integration with local health services; (v) EMTs clinical data record. Conclusions: The findings emerging from this study showed that NCDs significantly impact disaster response in different settings, underlining the need to implement a range of EMTs activities to guarantee assistance for chronic health needs. In view of strengthening the ability of health systems to cope with the NCDs’ burden, the EMTs’ initiatives should be considered as a bridge between the support provided during the acute phase of an emergency and the continuation of care ensured by the system in its early recovery phase.

Background: This study aimed to analyze the challenges faced by professionals and volunteers in search and rescue operations after the earthquake that struck the southeastern region of Turkey, with its epicenter in Kahramanmaraş, on 6 February 2023. Method: This research was conducted using a qualitative approach; specifically, a phenomenological method. It presents the results of semi-structured individual interviews with eight sampled volunteers who participated in the search and rescue activities following the earthquake. Participants were between the ages of 24 and 45, and three were nurses, three were journalists, and two were civilian volunteers with no formal training in search and rescue. In terms of nationality, five participants were citizens of the Turkish Republic of Northern Cyprus (TRNC) only, while three had both TRNC and Turkish citizenship. Field duties included providing medical support, documenting incidents, and assisting survivors in collaboration with civil society organizations. The research data were analyzed using MAXQDA Analytic Pro 2020. Results: Within the scope of this research, four main themes and twenty-one sub-themes were identified. The first theme is related to the nature of the traumatic events and reflects the characteristics of the traumatic experiences of the participants. The second theme is secondary trauma symptoms, showing that the participants experienced symptoms such as overstimulation, intrusive thoughts, sleep problems, anger, and concentration difficulties. The third theme focuses on post-traumatic growth symptoms. Participants reported experiencing developmental changes following trauma, such as changes in self-perception, the ability to recognize new situations, understanding the value of life, and positive relationships related to personal growth. Finally, the fourth theme is related to the coping skills used to cope with traumatic events; participants shared their coping strategies and the impact of these strategies. Conclusions: This study highlights the need to assess individuals in search and rescue operations in terms of secondary trauma. Our findings may be used as a reference to develop post-disaster psychosocial support services for volunteer search and rescue teams. Additionally, the findings can be used to renew the content of pre-field preparation training. Full article

Background: A rat robot can be constructed by electrically stimulating specific brain regions to control rat locomotion and behavior. The rat robot makes full use of the rat’s motor function and energy supply and has significant advantages in motor flexibility, environmental adaptability, and covertness. It can be widely used in disaster search and rescue, terrain survey, anti-terrorism, and explosion-proof tasks. However, the motor control of existing rat robots mainly relies on the virtual whisker touch produced by the electrical stimulation of the barrel area of the somatosensory cortex and the virtual reward generated by the electrical stimulation of the medial forebrain bundle. The methods requires substantial experimental training to encourage the animals to match the virtual sensation with the motor behavior. However, the conditioned reflexes acquired by the animals will gradually disappear after a period of time at the end of the experiments, which will lead to a decrease in the stability of the motor control system. Methods: In this study, we developed a new method to gain control of inclined movement in rats by the electrical stimulation of the ventral tegmental area (VTA) of the midbrain and motor control of steering in rats by the electrical stimulation of nigrostriatal (NS) pathway. Results: The results showed that the electrical stimulation of the rat VTA could induce stable inclined movement in rats and that the neuromodulatory effect significantly correlated with the electrical stimulation parameters. In addition, the electrical stimulation of the NS pathway was able to directly and stably induce the steering movements of the head and trunk to the contralateral side of the stimulated side of the rat. Conclusions: These findings are of great importance for the motor control of rat robots, especially in the field environment with many slopes. In addition, the rat robot constructed based on this method does not need pre-training while ensuring reliability, which greatly improves the preparation efficiency and has certain practical application value.

Background/Objectives: The dietary changes experienced by residents in long-term care facilities (LTCFs) following an earthquake are poorly understood. This study aimed to examine variations in nutritional status among residents of an Integrated Facility for Medical and Long-term Care (IFMLC), a particular type of Japanese LTCF, after the 2024 Noto Peninsula Earthquake. Methods: This descriptive study was conducted at the single IFMLC. A total of 115 residents living at the facility on 1 January 2024, at the time of the earthquake, were recruited for the study. The focus was the body weight and skeletal muscle mass changes observed before and after the earthquake. The observation period lasted for three months following the earthquake. Results: Water outage persisted for over a month, making dishwashing impossible and leading to an extended reliance on disposable dishes with limited capacity. This situation consequently reduced the variety and volume of meal options and overall energy intake meals. Residents’ body weight significantly decreased 3 months after the earthquake, and the prevalence of weight loss and skeletal muscle mass loss was particularly high in residents with normal swallowing function. To address nutritional deficiencies post-earthquake, the registered dietitian enhanced energy sufficiency through food fortification, oral nutritional supplements, and pre-prepared ready-to-hang liquid formulas. Conclusions: To prevent further weight and skeletal muscle mass reduction among IFMLC residents, providing ample water, and a disaster manual that can be used even with limited resources is essential. Furthermore, preparing for disasters by stockpiling foods and implementing strategies to enhance energy sufficiency is crucial. Full article

The intensity of typhoons affecting the Korean Peninsula has been rapidly increasing, resulting in significant damage. Notably, this intensification correlates with the rise in Sea Surface Temperature (SST) in the western Pacific Ocean and surrounding sea areas, where typhoons that impact the Korean Peninsula originate and develop. The SST in these regions is increasing at a faster rate than the global average. Typhoon-related meteorological disasters are not isolated events, such as strong winds, heavy rains, or storm surges, but rather multi-hazard occurrences that can affect different areas simultaneously. As a result, preparation and evaluation must address multi-hazard disasters, rather than focusing on individual weather phenomena. This study develops the Typhoon Ready System (TRS) to improve impact-based forecasting in Korea, in response to the growing threat of multi-hazard weather disasters. By providing region-specific pre-disaster information, the TRS enables local governments and individuals to better prepare for and mitigate the impacts of typhoons. The system will be continuously refined in collaboration with the U.S. Weather-Ready Nation (WRN), which possesses advanced impact forecasting capabilities. The findings of this study offer a crucial framework for enhancing Korea’s ability to forecast and respond to the escalating threats posed by typhoons. By utilizing the TRS, it will be possible to assess the risks of various multi-hazard weather disasters specific to each region during the typhoon forecast period, and the relevant data can be efficiently applied at both the individual and local government levels for typhoon prevention efforts. The system will be continuously improved through cooperation with the U.S. WRN, leveraging their advanced impact forecasting systems. It is expected that the TRS will enhance the accuracy of typhoon impact forecasts, which have been responsible for significant damage in Korea. Full article

The great 2015 Nepal earthquake of magnitude 7.6 killed about 9000 people. To better ensure a more coordinated disaster response, a Basic On-Site Disaster Medical Support (BOS-DMS) course was designed in 2017. This study evaluates the effectiveness of the BOS-DM course. The course was conducted twice and attended by 135 participants, of whom 113 (83.7%) answered pre-test and post-test based multiple-choice questions. Qualitative and quantitative feedback was provided by 94 participants (69.6%). Mean test scores for the participants increased from 4.24 ± 1.42 to 6.55 ± 2.16 (p-value < 0.0001; paired t-test). More than 92.0% of participants felt that the course prepared healthcare workers to manage acute medical situations at a disaster site. Subject knowledge scores increased from 34.8% to 90.2%. A three-day BOS_DMS course has the potential to improve on-site disaster management knowledge. Our study noted that precise scheduling, making attendance compulsory, translating course materials into the local language, inclusion of disaster exercises and training local master trainers can enhance course effectiveness.

Slavic folk culture is a fusion of Christian and of pre-Christian, pagan beliefs based on magic. This article is devoted specifically to ancient pre-Christian ideas about death and posthumous existence and the associated magical rituals and prohibitions, which persist to our time. It considers the following interactions between the living and the dead: 1. the measures taken and prohibitions observed by the living to ensure their well-being in the other world; 2. the measures taken by the living to ensure the well-being of their dead relatives in the other world (including funeral rites; memorial rites; cemetery visits; providing the dead with food, clothes, and items necessary for postmortem life; and sending messages to the other world); 3. communication between the living and the dead on certain days (including taking opportunities to meet, see, and hear them; treat them; prepare a bed for them; and wash them); 4. fear of the dead and their return and the desire to placate them to prevent them from causing natural disasters (hail, droughts, floods, etc.), crop failures, cattle deaths, diseases, and death; 5. magical ways for protecting oneself from the “walking dead”; 6. transforming the dead into mythological characters—for example, house-, water-, or forest-spirits and mermaids. The material presented in the article is drawn from published and archival sources collected by folklorists and ethnographers of the XIX and XX centuries in different regions of the Slavic world, as well as from field recordings made by the author and his colleagues in Polesie, the borderland of Belarus and Ukraine, in the 1960–1980s, in the Russian North and in the Carpathian region in the 1990s. It shows that the relationship between the living and the dead in folk beliefs does not fit comfortably within the widespread notion of an “ancestor cult”. It argues that the dead are both venerated and feared and that the living feel a dependence on their ancestors and a desire to strictly observe the boundary between the two worlds. Full article

Driven by the growing threat of natural disasters caused by climate change, there is an urgent need to strengthen the emergency rescue logistics network. However, insufficient research has been conducted on optimizing both pre-disaster preparation and post-disaster response, resulting in lower resilience and inefficiency of emergency logistics management. To this end, this study explores the optimization of emergency rescue resource allocation and transportation network design, considering the uncertainty and multi-period nature of natural disaster rescue. By employing a lateral transshipment strategy, a three-stage stochastic programming model is established, which aims to balance economic benefits with the need for devastations, thereby enhancing the resilience of the logistics network. Numerical experiments verify the effectiveness of the proposed model with different instances and the performance of the lateral transshipment strategy by comparing it with a two-stage stochastic programming model. Sensitivity analysis is performed on the costs of constructing a depot and the penalties for unmet needs. The analysis yielded valuable insights that can be used to enhance emergency rescue operations, supply chain network design, and logistics network design. The research outcome can benefit emergency responders and logistics professionals in optimizing their operations. Full article

Seismic networks in urban areas today represent key infrastructure to better address the tasks of earthquake preparation and mitigation in the pre-event phase, and are an important knowledge tool supporting disaster risk management during seismic crises and post-disaster recovery. In the last fifteen years, a decrease in instrumentation costs and the development of new low-cost devices have enhanced the deployment of several monitoring and experimental networks worldwide. This paper conducts a review of scientific work that refer to the deployment of Urban Seismic Networks (USN) in order to define the current state of the art. We collected a list of more than one hundred USNs worldwide that were operative within the period from 1994–2023. For each USN, we report the locations and objectives along with information about the timing, coverage, geometry, and technical characteristics (sensors and transmission). By reviewing all these aspects, this paper offers important insights to provide guidelines for new implementations, bearing in mind that the interest in monitoring urban areas is expected to continue to increase in the near future driven by population growth in urbanized areas.

On 20 July 2021, an extreme rainstorm battered Zhengzhou in China’s Henan Province, killing 302 people, including 14 individuals who drowned in a subway tunnel and 6 who drowned in a road tunnel. As the global climate warms, extreme weather events similar to the Zhengzhou flood will become more frequent, with increasingly catastrophic consequences for society. Taking a case study-based approach by focusing on the record-breaking Zhengzhou flood, this paper examines the governance capacity of inland cities in North China for managing extreme precipitation and flooding events from the perspective of the flood risk management process. Based on in-depth case analysis, our paper hypothesizes that inland cities in North China still have low risk perceptions of extreme weather events, which was manifested in insufficient pre-disaster preparation and prevention, poor risk communication, and slow emergency response. Accordingly, it is recommended that inland cities update their risk perceptions of extreme rainfall and flooding events, which are no longer low-probability, high-impact “black swans”, but turning into high-probability, high-impact “gray rhinos.” In particular, cities must make sufficient preparation for extreme weather events by revising contingency plans and strengthening their implementation, improving risk communication of meteorological warnings, and synchronizing emergency response with meteorological warnings.

Flooding has become one of the most dangerous and expensive disasters due to urbanization and climate change. Tools for assessing flood impact are required to support the shift of flood mitigation management from post-disaster recovery and reconstruction to community-driven pre-disaster warning and preparation. This study aims to develop an integrated approach to spatially assess the economic and social losses and ecological gain and identify the geographical factors of locations with high impacts of floods in Brisbane using the datasets collected from both the 2011 and 2022 flood events. Water depth, inundated area, land cover, ecosystem service value, mortality, and morbidity were considered to assess flood impacts. It is found that downstream (above 23,500 m from the upper stream) riverside communities (within 800 m of the river) with low altitudes (below 15 m) are more likely to experience significant flood damage. Flood impacts have bell-shaped developments with elevation and direct distance to the upstream river source and an exponential decline with distances to the river. These findings have implications for formulating future urban land use and community-tailored mitigation strategies, particularly for flood warning and preparation. Full article

This study assessed the risk perceptions among disaster relief nurses (DRNs) in Japan by focusing on 15 risk factors associated with frequent natural disasters and the ongoing coronavirus disease 2019 (COVID-19) pandemic. We conducted a cross-sectional study that targeted DRNs across six prefectures in Japan and explored nurses’ perceptions of risks including radiation exposure, volcanic eruptions, and mass infections. The findings indicated a heightened perception of radiation and nuclear-related risks. In the context of the COVID-19 pandemic, DRNs perceived “mass infection” as a significant risk. An age-based analysis revealed that younger nurses had more dread about “mass infection” and had heightened uncertainty about the “X-ray test” compared with their older peers. Understanding DRNs’ risk perceptions is crucial for effective disaster response preparedness and training. The study highlights the need to address these perceptions to ensure that DRNs are well prepared and supported in their roles. This study was not pre-registered on a publicly accessible registry.

Seismologists listen to Earth’s noise as it rips apart (faulting), exudes (volcanoes) and swallows (subducts) large volumes of rock. Your mobile phone is most likely detecting such noise, right now! This paper is about one such specific noise, the T wave. It summarises an early and successful piece of citizen science, performed within The University of Queensland Seismograph Stations (UQSS) observatory, in cooperation with colleagues at CSIRO. It was designed to encourage young STEM students from Brisbane high schools to engage in “real” research, back in 1995. Bear in mind, this is a time period when science is changing considerably from analog to digital media and operational recording methods. The citizen science students used a pre-prepared decadal collection (1980–1990) of T waves, derived from the Brisbane seismograph (BRS) observatory data catalogue. BRS has been operating since 1937 and is part of the global World-Wide Seismograph Station Network (WWSSN). Fortunately, seismology is a very collaborative field. There is a lot of data analysis involved in the science of recording earthquake signals, with auxiliary definitive catalogues, observers logbooks, housing of the recordings themselves (analog and digital) and the software mediums that change over time. It equally tests housekeeping proficiency, where a maze of record-keeping problems can be encountered in a longitudinal data collection study such as this. Having completed the project report, Earthquake generated T phases on BRS Seismograph (Brisbane, Q’ld) a predictor for Tasman Sea Tsunamis? their (analog) results sat in a cupboard until recently. The project was re-analysed in 2022 for a higher-degree student, discovering a timely climate change implication for the study. The original research question has now been amplified with a brief literature review. We observe that currently in Australia, university and government earth science observatories have diminished, and in their place, public seismic networks (PSN) have evolved, either in backyard sheds or school science labs. We now additionally propose here that the level of expertise required ideally fits the role of advancing citizen science, for a real science advantage. This is already a topical citizen disaster preparedness action area, and we propose that it has applications as a possible educational strategy for citizen engagement in today’s climate emergency. In addition, we are hopeful that other researchers in oceanography will read this paper and decide to explore the ocean’s temperature rise phenomenon through the eyes of seismological observers.

In view of the complexity, vagueness, and systematization of metal mine emergency rescue system evaluation, regret theory was introduced, and a comprehensive evaluation model of the metal mine emergency rescue system was established. Firstly, from four perspectives, including pre-emergency prevention, pre-emergency preparation, emergency rescue during an event, and post-disaster recovery and reconstruction, 26 influencing factors were selected to build a comprehensive evaluation index system of metal mine emergency rescue systems. Secondly, the G1 method and the anti-entropy weight method were used to determine the subjective weight and objective weight of the evaluation indicators, respectively, and the comprehensive weight of the indicator was determined based on game theory. The final evaluation level was determined by calculating the total evaluation value of the object to be evaluated. Finally, the established comprehensive evaluation model of a metal mine emergency rescue system based on game theory and regret theory was applied to Chengchao Iron Mine in Ezhou City, Hubei Province, and the evaluation results of this model were compared with those of fuzzy comprehensive evaluation and set pair analysis. The results showed that the calculation results of the evaluation model are reasonable and reliable, which can provide a new means of evaluating emergency rescue systems in metal mines. Full article

Commentary that observes the frequency of the appearances of images of disaster pervades much of the discourse surrounding postwar Japanese popular culture, and especially Japanese science fiction. Against such approaches, I argue that it is more productive to read these narratives of disaster through the critical lens of the genre’s engagement with the problem of futurity. My contention then is that these narratives of disaster do not merely function as imaginative repetitions or re-enactments of past events, but also take on an anticipatory quality, affectively preparing and the ground for and pre-empting responses to future events. I examine the work of Komatsu Sakyō (1931–2011) in particular, whose writing makes for an illustrative test case for articulating the premediative dimension of disaster narratives in postwar Japanese science fiction.
