Examining the performance of responding to the Khoy earthquake 2022, challenges, strengths, and lessons learned: thematic analysis.

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.

Predictive factors for acute kidney injury and amputation in crush injuries from the Kahramanmaras earthquakes.

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.

The effect of provincial policies on seismic disaster mitigation in China: An empirical study.

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.

Development of a scale examining post-disaster coping motivations in Turkey after the 6 February earthquake.

OBJECTIVES: The aim of this study was to develop the Motivations for Coping After Disaster Scale. To test the construct validity of the scale, a total of 676 data were collected from three different sampling groups (N1: 388; N2: 194; N3: 94). METHODS: Exploratory Factor Analysis, Confirmatory Factor Analysis (CFA) and Criterion validity analysis were conducted to test the construct validity of the scale. RESULTS: As a result of CFA, it was seen that the post-disaster scale had a five-dimensional structure (spiritual values, hope, friend support, solidarity, family support). The loadings of the items of the scale are at a good level. As a result of CFA, the scale was found to have acceptable and good fit indices (χ2/sd = 2.690; RMSEA (Root Mean Square Error of Approximation) = 0.066; SRMR (Standardized Root Mean Square Residual) = 0.047; CFI (Comparative Fit Index) = 0.948; GFI (Goodness of Fit Index) = 0.917). The results of the criterion validity analysis show that the scale has criterion validity. Cronbach Alpha internal consistency coefficient shows that the scale is highly reliable (Total = 0.923). CONCLUSIONS: The results of this study show that the Post-Disaster Coping Motivations Scale is a valid and reliable instrument. It is thought that the scale can make an important contribution to understanding psychological recovery processes after disaster and providing appropriate support to individuals.

Analysis of wound infections among pediatric patients following the 2023 Türkiye-Syria earthquakes.

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.

Experiences of adolescents affected by earthquakes: A qualitative study.

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.

Sleep Disturbance Caused by Step Changes in Railway Noise Exposure and Earthquakes.

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.

Meals in Shelters during Noto Peninsula Earthquakes Are Deficient in Energy and Protein for Older Adults Vulnerable to the Disaster: Challenges and Responses.

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.

A global map of species at risk of extinction due to natural hazards.

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.

Seismic resolution improving by a sequential convolutional neural network.

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.

The difficulty of nuclear emergency prevention measures during natural disasters: ongoing challenges in Japan.

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.

PTSD risk factors in earthquake survivors and their families: a systematic review.

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.

Islamic faith-based organisations and their role in building social capital for post-disaster recovery in Indonesia.

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.

The significance of local government in disaster management for international migrants: the case of Minoh City, Osaka Prefecture.

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.

Long term impact of Wenchuan earthquake on population mental and behavioral disorders in heavily-stricken areas: An ecological study based on big data.

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.

Longitudinal associations between post-traumatic stress and post-traumatic growth among older adults 11 years after a disaster.

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.

Gratitude practice helps undergraduates who experienced an earthquake in China find meaning in life.

This study was conducted following a magnitude 6.8 earthquake that occurred in early September 2022, coinciding with the commencement of a positive psychology course for the affected students. A sample of 479 Chinese undergraduates was recruited for an intervention focused on weekly gratitude practice. Data were collected through an online questionnaire package at 3 time points: the first week of the course (Time 1), the fifth week (Time 2), and the ninth week (Time 3), assessing gratitude, learning engagement, and the meaning of life. Findings revealed that gratitude significantly predicted meaning in life through learning engagement over time. This highlights the significant mediating role of learning engagement in the context of earthquakes and provides insights for positive interventions aimed at facilitating personal growth among emerging adults in higher educational settings, particularly those who have experienced traumatic events such as earthquakes.

The relationship between earthquake-induced post-traumatic stress disorder and breastfeeding attitude and behavior.

BACKGROUND: This study aimed to investigate the prevalence and severity of post-traumatic stress disorder (PTSD) and analyze the relationship between PTSD and breastfeeding attitudes and behaviors among breastfeeding mothers and women with children aged 0-24 months, all of whom had experienced the earthquake. METHODS: In this cross-sectional survey, a face-to-face questionnaire was administered to 173 earthquake survivors in Adiyaman, Turkey, during June and July 2023. The PTSD Checklist-Civilian scale was used to assess the presence of PTSD, while the Breastfeeding Attitudes of the Evaluation Scale (BAES) was employed to evaluate breastfeeding behaviors in mothers. RESULTS: Significantly higher PTSD scores (47.6 ± 17.4) were found among women staying in tents, while lower scores (37.0 ± 16.4) were observed in those who continued breastfeeding. 78.6% of women reported decreased breast milk because of the earthquake. Mothers with reduced milk supply had higher PTSD scores (46.1 ± 17.3). Breastfeeding training was associated with higher BAES scores (106.8 ± 56.8) and lower PTSD scores (32.5 ± 11.0). A significant negative correlation was observed between the PTSD score and BAES (r = -0.742; p < 0.001). CONCLUSIONS: The study demonstrated that breastfeeding may protect mothers against PTSD in the aftermath of earthquakes, emphasizing the importance of breastfeeding education. The higher frequency and severity of PTSD observed among earthquake survivor mothers residing in tents underscores the importance of promptly transitioning to permanent housing after the earthquake.
