ABSTRACT

OBJECTIVE: Disasters in developing countries result in higher human and financial losses compared to global standards, with the death rate being 12 times higher than that of developed countries. Many experts attribute the failures in disaster management to the lack of a system for documenting and analyzing disaster management functions and not leveraging the experiences and lessons learned. This study employed a qualitative data collection approach, utilizing semi-structured interviews with managers, deputies, members of operational teams, and individuals affected by the disaster in the area. This research aims to explore the challenges, strengths, and lessons learned from the response to the Khoy earthquake in Iran. RESULTS: After conducting 40 interviews and achieving data saturation, we extracted experiences and lessons learned to investigate the performance of responsible organizations in the 2022 Khoy earthquake. The obtained data were categorized into 8 categories and 39 sub-categories. These categories encompassed warning and calling forces, disaster assessment, disaster commanding, emergency housing, supply and distribution of items, organization, and guidance of public participation and charities, psychological support, logistics operations, monitoring, evaluation, documentation, information dissemination, and media management. Planners and operational managers can use the findings to review and revise their action and prevention plans.

ABSTRACT

PURPOSE: The aim of the study is to explore the experiences of adolescents affected by the earthquake. DESIGN AND METHODS: This study was carried out in a descriptive phenomenological design, which is a qualitative research method. This research was conducted as a qualitative investigation utilizing a phenomenological approach to explore the experiences of 12 adolescents through the purposeful snowball sampling method. The interviews were conducted with adolescents who affected by the Kahramanmaras earthquakes in a city located in the west of the country, between March 18, 2023 and June 30, 2023. Semistructured interviews were employed, and the data underwent inductive content analysis. COREQ reporting guidelines were used. RESULTS: The participants in this study vividly recounted experiencing intense fear and panic during the earthquake. Subsequent challenges emerged from the lack of coordination in aid efforts, struggles to secure shelter and necessities, and the profound loss of relatives. These adversities posed considerable physical and psychological challenges. Notably, the adolescents' ability to reflect on their past lives and reshape their perspectives proved instrumental in facilitating their adaptation to a new life. However, witnessing the demise of loved ones, grappling with the fear of death and loss, and incessantly discussing the earthquake hindered their adjustment. PRACTICE IMPLICATIONS: We found that adolescents experienced the quakes in three phases: in the moment, postquake, and adaptation to new life. The first theme underscores the limitations of current effectiveness of quake training. This finding has important implications for policy to better prepare the adolescent population for quake disasters. The second theme reveals that the communication and coordination problems experienced after the earthquake enable the weaknesses of the system to be noticed and political steps should be taken in this direction. The third theme focuses on the factors that increase or decrease the psychosocial adaptation of adolescents who have experienced this traumatic experience to the new life. This provides important clues to improve and support adolescent health.

ABSTRACT

BACKGROUND: Crush syndrome (CS) is characterized by high morbidity and mortality due to severe electrolyte disorders, circulatory dysfunction, and multiple organ failure, secondary to severe rhabdomyolysis and reperfusion injuries. Acute kidney injury (AKI) related to crush syndrome is one of the life-threatening complications and is the most frequent cause of death following earthquakes, other than trauma. We conducted a retrospective study to identify predictive parameters from clinical and laboratory data that aid in recognizing CS, assessing its severity, and evaluating acute kidney injury and amputation indications in patients. METHODS: We retrospectively evaluated the clinical data and laboratory follow-up of 33 patients treated for crush syndrome within the first two weeks following the February 6, 2023 earthquake. Patients who underwent surgery for crush syndrome but could not be followed post-surgery were excluded. Laboratory parameters were analyzed upon admission and then daily over an average seven-day follow-up. A p-value of <0.05 was considered statistically significant. Data analysis was performed using IBM SPSS Statistics 26.0 and R Studio software. RESULTS: Of the 33 patients, 17 were male and 16 were female. The incidence of AKI was 35.7%, 66.7%, and 100% in patients with injuries to one, two, and three extremities, respectively. A significant correlation was observed between total entrapment time and the duration of required dialysis days; AKI risk significantly increased with more than six hours of total entrapment time. Regarding the initial blood values upon hospital admission, a myoglobin level exceeding 2330 mg/dL demonstrated the highest sensitivity for predicting AKI. An initial uric acid level (>6.36 mg/dL) on admission had the highest specificity for predicting AKI. The initial myoglobin level (>3450 mg/dL) showed the highest sensitivity in predicting the need for amputation. Meanwhile, the mean creatine kinase (CK) level (>34800 U/L) exhibited the highest specificity but the lowest sensitivity for amputation prediction. CONCLUSION: The study analyzed the effectiveness and predictability of clinical and laboratory findings concerning amputation and acute kidney injury in crush syndrome resulting from earthquakes. Effective amputation management is a crucial factor influencing prognosis and survival in patients with earthquake-induced crush syndrome.

ABSTRACT

With the development of earthquake disaster reduction efforts in China, the content of earthquake disaster reduction policies has become increasingly enriched and improved. Particularly, multiple provincial governments have proposed earthquake disaster reduction planning policies. It is important to explore whether these policies can affect disaster mitigation. Therefore, this paper summarizes the earthquake disaster reduction plans and factors influencing seismic resilience. Panel data from 24 provinces between 2012 and 2021 were collected, and a difference-in-differences approach was used to construct an econometric model to evaluate the policy effects and analyze the enhancement of seismic resilience. The results show that the implementation of earthquake disaster reduction policies has a positive impact on earthquake monitoring, evacuation, and emergency relief capabilities, and the estimated policy effects are statistically significant. Moreover, a series of tests were conducted. The conclusions are as follows: (1) Earthquake disaster reduction policies have a positive impact on the improvement of seismic resilience in provinces. (2) Provinces with a higher number of earthquakes experience more significant effects from earthquake disaster reduction policies. (3) Provinces with higher seismic peak ground acceleration values exhibit more pronounced improvements in seismic resilience.

ABSTRACT

PURPOSE: On February 6, 2023, two earthquakes of magnitude 7.7 and 7.6 occurred consecutively in Turkey and Syria. This study aimed to investigate the predisposing factors for wound infection (WI) and the microbiological characteristics of wounds after earthquake-related injuries. METHODS: This descriptive study evaluated pediatric patients' frequency of WI, and the clinical and laboratory parameters associated with the development of WI were investigated. RESULTS: The study included 180 patients (91 female). The mean age of the patients was 123.9 ± 64.9 months and 81.7% (n = 147) of them had been trapped under rubble. Antibiotic treatment to prevent WI had been administered to 58.8% (n = 106) of all patients. WI was observed in 12.2% (n = 22) of the cases. In patients who developed WI, the incidence of exposure to a collapse, crush syndrome, compartment syndrome, multiple extremity injury, fasciotomy, amputation, peripheral nerve injury, thoracic compression, blood product use, intubation, and the use of central venous catheters, urinary catheters, and thoracic tubes were more frequent (p < 0.05). The need for blood product transfusion was associated with the development of WI (OR = 9.878 [95% CI: 2.504-38.960], p = 0.001). The negative predictive values of not developing WI at values of white blood cell count of < 11,630/mm3, creatine kinase < 810 U/L, potassium < 4.1 mEq/L, ALT < 29 U/L, AST < 32 U/L, and CRP < 45.8 mg/L were 93.7%, 96.8%, 90.8%, 93.3%, 100%, and 93.5%, respectively. Gram-negative pathogens (81%) were detected most frequently in cases of WI. Seventy-five percent of patients were multidrug- and extensively drug-resistant. CONCLUSION: This study leans empirical approach of our disaster circumstances. In cases with risk factors predisposing to the development of WI, it may be rational to start broad-spectrum antibiotics while considering the causative microorganisms and resistance profile to prevent morbidity.

ABSTRACT

Kyushu Shinkansen and conventional railway lines run parallel in the areas 5 km north of Kumamoto Station (northern area) and 12 km south of the station (southern area). Following the operation of the Kyushu Shinkansen Line in 2011, the adjacent conventional railway line in the north was elevated, a new station was operated in the south, and large earthquakes struck the Kumamoto area from March to April 2016. Sleep disturbances were compared before and after the interventions and earthquakes based on noise source (Shinkansen and conventional railways), area (northern and southern), and house type (detached and apartment) through socio-acoustic surveys from 2011 to 2017. The Shinkansen railway caused significantly less sleep disturbances in detached houses in the north after compared to before the earthquakes, presumably due to more frequent closures of bedroom windows in northern detached houses following the earthquakes. The Shinkansen railway caused significantly more sleep disturbances in apartments in the south after compared to before the earthquakes, presumably because the Shinkansen slowed down immediately after the earthquakes and returned to normal speed during the survey, suddenly increasing the noise exposure. There was no significant difference in the other six cases investigated. Overall, the interventions may not have caused significant differences in sleep disturbances. This article expands on the congress paper by Morihara et al. presented in the "Community Response to Noise" session at the 52nd International Congress and Exhibition on Noise Control Engineering in Makuhari, Japan, organized by the International Institute of Noise Control Engineering.

ABSTRACT

This paper investigates the role of Islamic faith-based organisations (FBOs) in Indonesia and examines the way in which their disaster recovery aid can be successful or less successful depending on social capital formation in communities affected by a disaster. The paper argues that Islamic FBOs play a prominent role in disaster-affected communities by building new social capital or strengthening existing social capital. Failure to do so may affect a community's recovery and its long-term resilience. Applying a framework that considers three types of social capital-bonding, bridging, and linking-from a comparative perspective, the paper discusses two cases of disaster recovery: one following the earthquake that struck Aceh in 2013; and the other after the Mount Kelud volcanic eruptions in East Java in 2014. In both instances, the findings highlight the importance of the village facilitator, cultural sensitivity, and understanding of local indigenous and religious practices for successful disaster recovery.

ABSTRACT

Disaster research predominantly focuses on citizens, not on migrants. This tilted spotlight needs to be readjusted, since many advanced countries around the world have become immigration countries, and safeguarding the lives of migrants at times of disaster has become an important and immediate policy issue. Hence, this research concentrates on disaster management to protect the lives of migrants in a disaster-prone and de facto immigration country. The particular country and event in question are Japan and the northern Osaka earthquake of June 2018. More than 100 migrants who lived near the earthquake's epicentre rushed to an evacuation shelter managed by the local municipal government of Minoh City, Osaka Prefecture. While non-governmental organisations attract more attention, this paper centres on a local government and demonstrates the key role that it can play in both bridging and building networks across different communities, and thus in safeguarding the lives of migrants at times of disaster.

ABSTRACT

BACKGROUND: Japan is a country often subject to natural disasters, influenced by a rapidly increasing aging demographic. The current research aims to analyze the food distribution for elderly evacuees who were relocated to a care facility in Wajima City, administered by the non-profit organization Tokushukai Medical Assistant Team (TMAT), post the Noto Peninsula Earthquake on 1 January 2024. A significant portion of the shelter's inhabitants were elderly individuals. METHODS: TMAT's operations began immediately after the calamity, concentrating on evaluating the nutritional content of meals provided during the initial and subsequent phases, along with a thorough nutritional assessment. During this process, researchers examined the meal conditions for evacuees, including the elderly and those with disabilities, observed the actual meal distribution at welfare centers, and discussed the challenges and potential solutions. RESULT: Throughout the TMAT mission, a total of 700 evacuees received assistance, with 65% being 65 years old or above. An analysis of the nutritional content of the 10 meal varieties served at the shelter revealed inadequate energy and protein levels for elderly individuals, particularly men, indicating the need for future enhancements. CONCLUSIONS: Following a detailed evaluation of TMAT's response to the Noto Peninsula earthquake, it was determined that the food provided in the shelters in the affected areas did not meet the nutritional needs of elderly individuals, especially men, based on nutritional analysis. To stress the importance of establishing an effective framework, it is recommended to promptly revise the emergency food provisions for the elderly population, considering they constitute the majority of the affected individuals.

ABSTRACT

Background: Exposure to earthquakes can cause adverse effects on the mental health of survivors, including an increased risk of PTSD.Objective: This systematic review aims to analyse the previous secondary studies to identify the risk factors for PTSD from children to elderly earthquake survivors. In addition, it aims to consider the complexity of the joint effects of the individual, relational, and contextual risk factors, to also detect the most at-risk families.Method: After reviewing and screening studies from the literature search through PubMed, Web of Science, Scopus, and EBSCO under the guidance of PRISMA guidelines, ten eligible secondary studies were identified that examine the risk factors for PTSD in individuals (from children to elderly) affected by worldwide earthquakes.Results: The analysis of the included studies allowed the identification of a series of socio-demographic, pre-traumatic, peri-traumatic, and post-traumatic PTSD risk factors in children, adolescents, youth, adults, and elderly survivors. The results represent the complexity of the joint effects of these risk factors at individual, relational, and contextual levels.Conclusions: The consideration of the PTSD risk factors highlights the importance of individual characteristics and the type of experiences and exposure in the period before, during, and after the earthquake. This knowledge could allow the early identification of at-risk individuals of different ages and families and the implementation of intervention programmes.


This is the first systematic review to identify PTSD risk factors from children to elderly earthquake survivors using secondary studies.Considering the complexity of the joint effects at individual, relational, and contextual levels, several socio-demographic, pre-traumatic, peri-traumatic, and post-traumatic risk factors for PTSD were identified in the age groups considered. Moreover, the consideration of these factors could help the identification of at-risk families.The identification of risk factors for PTSD across the lifespan could provide helpful knowledge for prevention and intervention programmes.

ABSTRACT

An often-overlooked question of the biodiversity crisis is how natural hazards contribute to species extinction risk. To address this issue, we explored how four natural hazards, earthquakes, hurricanes, tsunamis, and volcanoes, overlapped with the distribution ranges of amphibians, birds, mammals, and reptiles that have either narrow distributions or populations with few mature individuals. To assess which species are at risk from these natural hazards, we combined the frequency and magnitude of each natural hazard to estimate their impact. We considered species at risk if they overlapped with regions where any of the four natural hazards historically occurred (n = 3,722). Those species with at least a quarter of their range subjected to a high relative impact were considered at high risk (n = 2,001) of extinction due to natural hazards. In total, 834 reptiles, 617 amphibians, 302 birds, and 248 mammals were at high risk and they were mainly distributed on islands and in the tropics. Hurricanes (n = 983) and earthquakes (n = 868) affected most species, while tsunamis (n = 272), and volcanoes (n = 171) affected considerably fewer. The region with the highest number of species at high risk was the Pacific Ring of Fire, especially due to volcanoes, earthquakes, and tsunamis, while hurricane-related high-risk species were concentrated in the Caribbean Sea, Gulf of Mexico, and northwestern Pacific Ocean. Our study provides important information regarding the species at risk due to natural hazards and can help guide conservation attention and efforts to safeguard their survival.

ABSTRACT

BACKGROUND: This study aimed to explore and evaluate the development trends and differential changes in the prevalence of mental and behavioral disorders among the earthquake survivors in exposure groups (highly hard-hit areas) and control groups (general disaster areas) from 2015 to 2019, as well as to investigate the potential influencing factors. METHODS: Data was obtained from the Sichuan Health Information System and the Sichuan Health Yearbook, the prevalence of the exposure group and the control group were calculated, the difference between the two groups was evaluated using the prevalence rate ratio, and a fixed effect model was developed to investigate the potential influencing factors of the prevalence. RESULTS: The prevalence by gender and age in the exposure group was always greater than those in the control group (RR>1), although the disparity between the two proceeded to diminish with time. The urbanization rate (ß = 0.0448, P < 0.05) and disaster area levels (ß = 0.0104, P < 0.05) were risk factors for the prevalence of mental and behavioral disorders. LIMITATIONS: The study only collected data at the group level following the Wenchuan earthquake. Consequently, the findings are only applicable at the group level. Furthermore, diagnostic criteria for various types of mental and behavioral disorders diseases were not provided. CONCLUSIONS: The earthquake has a significant long-term impact on mental health. It is necessary to continuously monitor the mental health of Wenchuan earthquake survivors and take appropriate post-disaster intervention measures.

ABSTRACT

AIMS: Previous studies have reported inconsistent findings regarding the association between post-traumatic stress (PTS) and post-traumatic growth (PTG). Three major issues could account for this inconsistency: (1) the lack of information about mental health problems before the disaster, (2) the concept of PTG is still under scrutiny for potentially being an illusionary perception of personal growth and (3) the overlooking of PTS comorbidities as time-dependent confounding factors. To address these issues, we explored the associations of PTS and PTG with trauma-related diseases and examined the association between PTS and PTG using marginal structural models to address time-dependent confounding, considering pre-disaster covariates, among older survivors of the 2011 Japan Earthquake and Tsunami. METHODS: Seven months before the disaster, the baseline survey was implemented to ask older adults about their health in a city located 80 km west of the epicentre. After the disaster, we implemented follow-up surveys approximately every 3 years to collect information about PTS and comorbidities (depressive symptoms, smoking and drinking). We asked respondents about their PTG in the 2022 survey (n = 1,489 in the five-wave panel data). RESULTS: PTG was protectively associated with functional disability (coefficient -0.47, 95% confidence interval (CI) -0.82, -0.12, P < 0.01) and cognitive decline assessed by trained investigators (coefficient -0.07, 95% CI -0.11, -0.03, P < 0.01) and physicians (coefficient -0.06, 95% CI -0.11, -0.02, P < 0.01), while PTS was not significantly associated with them. Severely affected PTS (binary variable) was associated with higher PTG scores, even after adjusting for depressive symptoms, smoking and drinking as time-dependent confounders (coefficient 0.35, 95% CI 0.24, 0.46, P < 0.01). We also found that an ordinal variable of the PTS score had an inverse U-shaped association with PTG. CONCLUSION: PTG and PTS were differentially associated with functional and cognitive disabilities. Thus, PTG might not simply be a cognitive bias among survivors with severe PTS. The results also indicated that the number of symptoms in PTS had an inverse U-shaped association with PTG. Our findings provided robust support for the theory of PTG, suggesting that moderate levels of psychological struggles (i.e., PTS) are essential for achieving PTG, whereas intense PTS may hinder the attainment of PTG. From a clinical perspective, interventions that encourage social support could be beneficial in achieving PTG by facilitating deliberate rumination.

ABSTRACT

It is crucial to anticipate nuclear emergency scenarios and implement effective measures. Japan's climate and topography make it vulnerable to natural disasters; thus, it is necessary to address compounding and cascading disaster scenarios involving the simultaneous occurrence of natural and nuclear disasters. On 1 January 2024, an earthquake hit the Noto region of Ishikawa Prefecture, resulting in damage to the area around the Shika Nuclear Power Plant, located 90 km from the epicenter. This earthquake revealed that, in the event of a complex disaster, it is possible that residents living within 30 km of the Shika Nuclear Power Plant will be completely unprepared for a nuclear disaster. In the event of a complex disaster, it is crucial to implement appropriate countermeasures while balancing responses to both nuclear and natural disasters and optimizing radiation disaster prevention measures.

ABSTRACT

Thin-bed soft rock is one of the main factors causing large deformations of tunnels. In addition to relying on some innovative construction techniques, detecting thin beds early during surface geological exploration and advanced geological prediction can provide a basis for planning and implementing effective coping measures. The commonly used seismic methods cannot meet the requirement for thin beds detection accuracy. A high-resolution (HR) seismic signal processing method is proposed by introducing a sequential convolutional neural network (SCNN). The deep learning dataset including low-resolution (LR) and HR seismic is firstly prepared through forward modeling. Then, a one-dimension (1D) SCNN architecture is proposed to establish the mapping relationship between LR and HR sequences. Training on the prepared dataset, the HR seismic processing model with high accuracy is achieved and applied to some practical seismic data. The applications on both poststack and prestack seismic data demonstrate that the trained HR processing model can effectively improve the seismic resolution and restore the high-frequency seismic energy so that to recognize the thin-bed rocks.

ABSTRACT

OBJECTIVES: Disaster evacuation increases the risk of becoming overweight or obese owing to lifestyle changes and psychosocial factors. This study evaluated the effect of evacuation on becoming overweight during a 7-year follow-up among residents of Fukushima Prefecture during the Great East Japan Earthquake. STUDY DESIGN: This was a prospective cohort study. METHODS: We analysed data collected from 18,977 non-overweight Japanese participants who completed the 'Comprehensive Health Checkup Program' and 'Mental Health and Lifestyle Survey', as part of the Fukushima Health Management Survey, between July 2011 and November 2012. An evacuation was defined as the moving out of residents of municipalities designated as an evacuation zone by the government or having a self-reported experience of moving into shelters or temporary housing. Follow-up examinations were conducted in March 2018 to identify patients who became overweight. Hazard ratios (HRs) and 95% confidence intervals (95% CIs) were calculated using a Cox proportional hazards regression model. RESULTS: Among 15,875 participants (6091 men and 9784 women; mean age 63.0 ± 11.1 years) who received follow-up examination (mean follow-up, 4.29 years), 2042 (856 men and 1186 women) became overweight. Age-, baseline body mass index-, lifestyle-, and psychosocial status-adjusted HRs (95% CIs) for becoming overweight after evacuation were 1.44 (1.24-1.66) for men and 1.66 (1.47-1.89) for women. CONCLUSION: Evacuation was associated with the risk of becoming overweight 7 years after the disaster. Thus, maintaining physical activity, healthy diet, and sleep quality and removing barriers to healthy behaviour caused by disasters, including anxiety concerning radiation, may prevent this health risk among evacuees.

ABSTRACT

INTRODUCTION: On February 6, 2023, two separate destructive earthquakes with magnitudes of 7.7 and 7.5 occurred in Kahramanmaras, Türkiye. More than 50,000 people lost their lives, and over 100,000 were reported injured. In this study, patients referred to hospitals with burn diagnosis and management of burn wounds following the disaster were evaluated. MATERIAL AND METHODS: Information on burn injury admissions related to the earthquake was collected from all burn facilities in the country within 15 days after the earthquake. The patients' demographics, being under rubble, rescue times, burn causes, grafting procedures, and deaths were recorded. RESULTS: Following the earthquake, burn victims were transferred to the 13 Burn Treatment Centers located in 10 provinces. A total of 191 patients were burned. Among the burn patients, 101 (52.9%) were rescued from the rubble 2-60 h after the earthquake. Eight patients who were hospitalized at the burn centers died. Scalding and flame burns were the most common etiologies. Burned total body surface area, concomitant crush injury, hospitalization, and mortality was higher among the patients trapped under rubble (p < 0.001, p < 0.001, p < 0.001, and p < 0.001, respectively). Victims who stayed longer time under the rubble required significantly more grafting procedures (p < 0.001). CONCLUSION: In a literature review, it was observed that there are a limited number of publications reporting earthquake-related burns. In the February, 6 Türkiye earthquake, flame burns were seen due to small fires that occurred in collapsed buildings during the earthquake. And also contact burns and hot liquid burns were seen in earthquake victims trapped under rubble. Bursting hot water pipes, overturned stoves, contact with hot central heating radiators, and heated construction irons caused scalding and contact burns. It is believed that prolonged entrapment may cause delays in burn treatment or lead to deeper burns due to prolonged contact with the burning agent, increasing hospitalization rates. This earthquake once again drew attention to burn injuries that could occur during and after earthquakes, including those that may occur under rubble.

ABSTRACT

Effective relief reduces damages and protects people during natural disasters, such as earthquakes. This research proposes a data-driven model based on sustainability, taking into account the pre and post-crisis simultaneously. Real data was used to validate the model in various earthquake scenarios. The study addresses questions regarding the amount and allocation of relief goods during earthquakes. This research is carried out in two phases: simulation and modeling. The purpose of the simulation phase is to estimate the number of relief goods in different scenarios. Additionally, in the modeling phase, a data-based multi-objective model is presented, considering sustainability, to minimize the lack of relief goods, the number of untreated wounded, and supply chain costs. Using the dynamic simulation system, and after designing the structure of the earthquake effects on urban infrastructure, the actions and effects of the earthquake on vital arteries are investigated in different scenarios, and scenarios with a higher degree of risk are identified. The results showed that the highest and lowest demands for relief goods were related to the "Mosha-day fault" and "North Tehran-night fault" scenarios, respectively.
