Coral geochemical response to uplift in the aftermath of the 2005 Nias-Simeulue earthquake.

On 28 March 2005, the Indonesian islands of Nias and Simeulue experienced a powerful Mw 8.6 earthquake and coseismic uplift and subsidence. In areas of coastal uplift (up to ~ 2.8 m), fringing reef coral communities were killed by exposure, while deeper corals that survived were subjected to habitats with altered runoff, sediment and nutrient regimes. Here we present time-series (2000-2009) of Mn/Ca, Y/Ca and Ba/Ca variability in massive Porites corals from Nias to assess the environmental impact of a wide range of vertical displacement (+ 2.5 m to - 0.4 m). High-resolution LA-ICP-MS measurements show that skeletal Mn/Ca increased at uplifted sites, regardless of reef type, indicating a post-earthquake increase in suspended sediment delivery. Transient and/or long-term increases in skeletal Y/Ca at all uplift sites support the idea of increased sediment delivery. Coral Mn/Ca and Ba/Ca in lagoonal environments highlight the additional influences of reef bathymetry, wind-driven sediment resuspension, and phytoplankton blooms on coral geochemistry. Together, the results show that the Nias reefs adapted to fundamentally altered hydrographic conditions. We show how centuries of repeated subsidence and uplift during great-earthquake cycles along the Sunda megathrust may have shaped the modern-day predominance of massive scleractinian corals on the West Sumatran reefs.

Long-term mental health and resilience of the first responders in Japanese ground self-defense forces engaging body recovery after the great east Japan earthquake.

Handling human remains is extremely difficult and stressful task, and it can contribute to the development of stress-related mental health problems. To prevent disaster from the development of mental disorders in first responders, it will be important to elucidate factors sustaining psychological well-being following the events requiring handling of human remains. Japanese Ground Self-Defense Forces (JGSDF) first responders (n = 146), involved in human remains recovery after the Great East Japan Earthquake (GEJE) participated. We examined the psychological resilience (S-H Resilience Test), depressive symptoms (SDS), and psychological distress (GHQ-28) 6 years after GEJE, in three groups; Group A: no contact no view of human remains, B: view only of human remains, and C: direct handling of human remains. S-H Resilience test evaluated the 3 subclasses of resilience; Social Support, Self Efficacy, Sociality. One-way ANOVA revealed the significant difference in resilience scores between Group B and C without any differences in depressive symptoms or psychological distress among the 3 groups. Multiple regression analyses revealed that depressive symptoms and resilience were associated with psychological distress in all participants. Path analyses showed that whereas one subtype of resilience indirectly reduced psychological distress through lower depressive symptoms in Group A (Social Support) and Group B (Sociality), both subtypes of resilience indirectly reduced psychological distress by lowering depressive symptoms in Group C. These findings suggest that exposure to higher stressful situation may decrease the psychological resilience based on the S-H Resilience test, and two subtypes of resilience may be necessary to sustain the psychological well-being.

From Tragedy to Resilience in a University Hospital: Characteristics of Patients in the Aftermath of the 2023 Turkey Earthquake.

OBJECTIVE: This study focuses on adults affected by the February 2023 Turkey earthquakes, aiming to uncover demographic and clinical traits. METHODS: A retrospective analysis of data from adult patients who sought emergency care between February 6 and February 21, 2023, following the earthquakes, was conducted. RESULTS: Among 3072 patients, 1544 (50.3%) of whom were women, trauma (31.1%) was the most prevalent cause of emergency department presentations. The median age of all patients was 44 y (interquartile range [IQR] 31-61 y). Hatay province accounted for 65.2% of trauma patients as origin. Most of the patients (66.8%) presented to the emergency department by their own means, while this was opposite for trauma patients, of whom 54.5% was transferred by means of Ambulance Service. Half of the total trauma patients were rescued from the debris, and 75.9% sustained limb injuries. Crush syndrome affected 24.7%, and emergency hemodialysis was performed on 9.1%, whereas emergency surgery was performed on 22.8% of all trauma cases. Overall, 10.2% of trauma patients lacked any identification. The rate of emergency department admittions due to respiratory and cardiovascular diseases was higher at the time of the earthquake compared with the previous year (P < 0.001). CONCLUSIONS: The insights gained from this study hold valuable implications for disaster response strategies, emphasizing the importance of preparedness, timely intervention, and comprehensive patient care.

Evaluation of the demographic characteristics and general health status of earthquake survivors affected by the 2023 Kahramanmaras earthquake; a section from Gaziantep Nurdagi district.

BACKGROUND: An earthquake with a magnitude of 7.7 occurred in Pazarcik District of Turkey at 04.17 on February 6, 2023 and another earthquake of 7.6 occurred at 13.24 on the same day. This is the second largest earthquake to have occurred in Turkey. The aim of this study is to investigate the earthquake-related level of knowledge, attitudes and behaviours, general health and psychological status of survivors who were affected by the 2023 Kahramanmaras Earthquake and who were living in Nurdagi District of Gaziantep after the earthquake. METHODS: Data of 2317 individuals older than 18 years of age who were living in earthquake neighbourhoods, tents and containers in Nurdagi District of Gaziantep were examined. Variables were evaluated to find out the demographic characteristics and general health status of earthquake victims. General Health Questionnaire (GHQ-12) was used to find out psychological states of earthquake victims. RESULTS: The rate of injuries was 14.2% and leg and foot injuries were the most common with 44.2%. The relationship between injury status; and age, marital status, and being trapped under debris was revealed (p < 0.05). Mean GHQ-12 score of the survivors was 3.81 ± 2.81 and 51.9% experienced psychological distress. In the evaluation with logistic regression, it was found that female gender, being injured in the earthquake, loss of first degree and second degree relatives (with a higher rate in loss of first degree relative), having a severely damaged -to be demolished house and having a completely destroyed house were correlated with higher level of psychological distress (p < 0.05). CONCLUSION: General characteristics, injury prevalence and affecting factors of earthquake survivors were evaluated in the present study. Psychological distress was found in victims. For this reason, providing protective and assistive services to fight the destructive effects of earthquake is vital. Accordingly, increasing the awareness of people residing in earthquake zones regarding earthquakes is exceptionally important.

Exploring Volunteer Pharmacists' Experiences in Responding to 2023 Türkiye Earthquakes: A Qualitative Phenomenological Study.

OBJECTIVE: Pharmacists are vital in disaster response efforts, dispensing essential medications, managing pharmacy services, consulting, and educating survivors regarding their medications. Their contributions, however, are often underrepresented in scientific literature. This study aimed to explore the experiences of pharmacists who provided pharmacy services to meet the pharmaceutical needs of the survivors after 2 major earthquakes in Türkiye in 2023. METHODS: This study adopted a phenomenological approach. Data were collected using semi-structured interviews. Purposive sampling was used to invite pharmacists who provided pharmacy services to survivors. Interview transcripts were analyzed following an inductive, reflexive thematic analysis. RESULTS: In total, 15 pharmacists were interviewed. Four main overarching themes "response to the earthquake," "preparedness for the earthquake," "experiences during service delivery," and "mental and physical experiences" were developed. CONCLUSIONS: From participants' experiences, it is essential to expand the clinical responsibilities of pharmacists and train them in providing wound care, administering immunization, and prescribing. Pharmacists should be integrated as essential members of disaster health teams. International health organizations, nongovernmental organizations, and governments are encouraged to work collaboratively and develop disaster management plans including pharmacists in early responders. This might help mitigate the deficiencies and overcome challenges in health-care systems to provide effective patient-centered care by health professionals and respond effectively to disasters.

Digital Response to Physical Crises: The Role of an E-Health Platform in the 2023 Southern Turkey Earthquakes.

The catastrophic earthquakes that struck Southern Turkey in 2023 highlighted the pressing need for effective disaster management strategies. The unprecedented scale of the crisis tested the robustness of traditional healthcare responses and highlighted the potential of e-health solutions. Despite the deployment of Emergency Medical Teams, initial responders - primarily survivors of the earthquakes - faced an enormous challenge due to their lack of training in mass-casualty situations. An e-health platform was introduced to support these first responders, offering tools for drug calculations, case management guidelines, and a deep learning model for pediatric X-ray analysis. This commentary presents an analysis of the platform's use and contributes to the growing discourse on integrating digital health technologies in disaster response and management.

Neuropathic pain and mood disorders in earthquake survivors with peripheral nerve injuries.

Background and purpose:

        Natural disasters, such as earthquakes, frequently result in mood disorders among affected individuals. It is established that neuropathic pain arising from traumatic neuropathies is also linked to mood disorders. This study investigates the influence of neuropathic pain on the development of mood disorders in earthquake survivors with peripheral nerve injuries, following the earthquake centered in Kahramanmaras on February 6, 2023. Additionally, we aim to assess the electro­physiological aspects of neuropathic injuries in these survivors.

The study comprised 46 earth-quake survivors with electrophysiologically confirmed peripheral nerve injuries, with 39 trauma-free survivors serving as the control group. Neuropathic pain, anxiety and depression were assessed using the Douleur Neuropathique 4 (DN4) questionnaire and the Hospital Anxiety and Depression Scale (HADS).

Our findings revealed that the ulnar and peroneal nerves were the most commonly injured structures. Among the survivors with peripheral nerve injury, 31 out of 46 (67%) were found to experience neuropathic pain. Furthermore, plexopathy and multiple extremity injuries were associated with more severe neuropathic pain. However, there was no significant difference in anxiety and depression scores between the two groups and neuropathic pain was found to have no independent effect.

The study indicates that the intensity of neuropathic pain varies based on the localization and distribution of peripheral nerve injuries. However, the presence of peripheral nerve damage or neuropathic pain was not directly associated with HADS scores, suggesting that mood disorders following disasters may have multifactorial causes beyond physical trauma.

A scoping review of post-earthquake healthcare for vulnerable groups of the 2023 Turkey-Syria earthquakes.

BACKGROUND: Identifying healthcare services and also strengthening the healthcare systems to effectively deliver them in the aftermath of large-scale disasters like the 2023 Turkey-Syria earthquakes, especially for vulnerable groups cannot be emphasized enough. This study aimed at identifying the interventions undertaken or proposed for addressing the health needs or challenges of vulnerable groups immediately after the occurrence of the 2023 Turkey-Syria earthquakes, as well as for prioritizing their healthcare service delivery in the post-Turkey-Syria earthquake. METHODS: In this scoping review compiled with the five steps of the Arksey and O'Malley framework, five databases, including PubMed, Science Direct, Web of Science, OVID, and Google Scholar, were searched for studies published between March and April 2023 in line with the eligibility criteria. Interventions for enhancing post-earthquake healthcare services (PEHS) were grouped into seven (7) categories, adopted from previous guidelines and studies. Each one was assigned a default score of a value equal to one (1), which, in the end, was summed up. RESULTS: Of the 115 total records initially screened, 29 articles were eligible for review. Different interventions they reported either undertaken or proposed to address the healthcare needs and challenges, especially faced by the most vulnerable groups in the aftermath of the Turkey-Syria earthquakes, were categorized into 7 PEHS. They were ranked with their scores as follows: humanitarian health relief (25); medical care (17); mental health and psychosocial support (10); health promotion, education, and awareness (9); disease surveillance and prevention (7); disability rehabilitation (7); and sexual and reproductive health (5). CONCLUSION: Since there are no proper guidelines or recommendations about the specific or most significant PEHS to prioritize for vulnerable groups after the occurrence of large-scale earthquakes, this scoping review provides some insights that can help inform healthcare service delivery and prioritization for vulnerable groups in the post-2023 Turkey-Syria earthquakes and other similar disasters.

Turning pain into strength: prosocial behaviours in coping with trauma.

Background: Various coping strategies have been shown to alleviate the negative effects of trauma, yet the significance of prosocial behaviour in this realm has been notably underexplored. The present study explored the hypothesis that engaging in prosocial behaviour mitigates the impacts of trauma by promoting a sense of competence and relatedness, post-traumatic growth (PTG), and reconstruction of meaning.Methods: Three consecutive studies were conducted with college students to compare differences in consequence of prosocial behaviours between a trauma group and a control group. Study 1 (N = 96) used self-reported experiences of traumatic vs non-traumatic events; Study 2 (N = 43) used exposure vs. no exposure to video of an earthquake; Study 3 (N = 20) used a randomized controlled trial (RCT) of a prosocial-themed intervention vs. no intervention. Outcomes in all studies were assessed by self-report questionnaires.Results: Trauma damaged participants' sense of competence and meaningfulness. Prosocial behaviour relieved the impact of trauma on meaning, specifically manifested in the individuals' sense of meaningfulness and their search for meaning. Group interventions with a prosocial theme (based on effect size results) reduced post-traumatic stress disorder (PTSD) and enhanced PTG in victims. The promoting effect on PTG persisted a month later, and its enhancing effect on meaning manifested with a delay.Conclusion: Prosocial behaviour can potentially serve as a beneficial strategy for individuals coping with trauma because it helps enhance meaning and promotes PTG in victims. This conclusion is supported by laboratory experiments and a tentative small-scale intervention study, which provide an innovative perspective for future trauma interventions.

The impact of creatine kinase and base excess on the clinical outcome of crush injuries sustained during the Kahramanmaras/Turkey earthquakes on February 6, 2023.

The aim of the study is to determine the usefulness of base excess (BE) and creatine kinase (CK) in predicting the extent of damage to the extremities, the need for hemodialysis, and the likelihood of mortality in crush injuries. Our study included patients who were affected by the earthquakes that occurred in Kahramanmaras/Turkey on February 6, 2023 and were diagnosed with crush injuries. The study was a retrospective observational study. We used chi-square test, independent sample t test, analysis of variance (ANOVA) to examine whether CK and BE values can be used to predict damage to the extremities, hemodialysis requirement, and mortality. A total of 299 patients were included in the study. A statistically significant relationship was found between BE and extremity damage, hemodialysis requirement, and mortality (P < .005). A statistically significant difference was also seen in terms of extremity damage and hemodialysis requirement with CK (P < .001), while there was no statistically significant difference seen in mortality (P = .204). BE may serve as a predictive biomarker for the development of extremities damage, hemodialysis requirement, and mortality. CK is not predictive of mortality.

Understanding paleo-earthquakes in the Kuril Trench based on Late-Holocene tsunami deposits in the distal region from wave sources, northern Hidaka, Hokkaido, Japan.

Geological evidence, such as tsunami deposits, is crucial for studying the largest rupture zone of the Kuril Trench in Hokkaido, Japan, due to its poor historical record. Although 17th-century tsunami deposits are widely distributed across Hokkaido, the presence of multiple wave sources during that period, including the collapse of Mt. Komagatake, complicates the correlation with their wave sources. Understanding the regional distribution of these tsunami deposits can provide valuable data to estimate the magnitude of megathrust earthquakes in the Kuril Trench. The northern part of Hidaka, Hokkaido, where tsunamis from multiple wave sources are expected to overlap, is distant from the Kuril Trench. To clarify the depositional history of tsunami deposits in such distal areas, evaluating the influence of the depositional environments on the event layer preservation becomes even more critical. We conducted field surveys in Kabari, located in the northern Hidaka region, identifying three sand layers from the 10th to the 17th century and two layers dating beyond 2.3 thousand years ago. The depositional ages of most sand layers potentially correlate with tsunami deposits resulting from the Kuril Trench earthquakes. Utilizing reconstructed paleo-sea level data, we estimated that most sand layers reached approximately 2 m in height. However, it is noteworthy that the latest sand layer from the 17th century exhibited an unusual distribution, more than 3 m in height. This suggests a different wave source as the Mt. Komagatake collapse. The discovery of multiple sand layers and their distributions is crucial to constraining the maximum magnitude of giant earthquakes in the Kuril Trench and understanding the volcanic tsunami events related to Mt. Komagatake.

Recovering a lost seismic disaster. The destruction of El Castillejo and the discovery of the earliest historic earthquake affecting the Granada region (Spain).

This paper discusses recent archaeological fieldwork conducted at El Castillejo, a medieval Islamic settlement in Los Guájares, Granada, southern Spain. Results from combined archaeological excavation and archaeoseismological assessment of standing structures suggest that the site was affected by a destructive earthquake during its occupation. Radiocarbon samples and OSL analysis point to a seismic event in the period CE 1224-1266. The earthquake occurred within an area marked by a 'seismological gap' in terms of historic seismicity and the causative fault has been tentatively identified in the Nigüelas-Padul Fault System which lies north of the settlement. This event is not recorded by national or European seismic catalogues and represents the oldest historic earthquake in the Granada area. Our work stresses the significant impact that targeted archaeological investigations can generate in our understanding of the local historic seismicity, thus providing clear implications for seismic disaster prevention and reduction.

After an Earthquake: The Comparison of Psychological Status of Resident and Earthquake Survivor Cancer Patients.

OBJECTIVE: Natural disasters such as earthquakes can have a significant impact on cancer treatment and care. The objective of the study was to evaluate the psychological effect of the earthquake on survivor cancer patients compared to regular cancer patients. METHODS: Cancer patients who were evacuated from earthquake sites and referred for the continuation of their treatment, as well as regular resident patients were included in the study. The resident cancer patients were compared with the study population as a control group. DASS-21 forms were filled based on patients' declarations. RESULTS: Forty-six patients were earthquake survivors and 55 were resident cancer patients. Stress scores were significantly higher in earthquake survivors (P = 0.021). In contrast, there was no difference in stratified groups due to DASS-21 categorization in stress scores while depression and anxiety subgroups had significant differences (P = 0.012; P < 0.001). Also, women significantly had a worse outcome in the depression and anxiety categories (P = 0.028; P = 0.021) while no difference was observed in men. CONCLUSION: Recent earthquakes in Turkey had psychological negative effects on oncology patients. The increased stress, depression, and anxiety levels were observed in earthquake survivors who were evacuated from the disaster zone and compared to the control group.

Evaluation of Incoming Messages to WhatsApp Communication Network Created by Volunteers in Major Disasters: The Case of Turkey Earthquake.

OBJECTIVE: This research was conducted in order to assess the 1-week aid needs determined by the health professional who voluntarily served in the WhatsApp communication network during the earthquakes in Kahramanmaras, Turkey. METHODS: This descriptive retrospective epidemiological study focuses on the 1-week messaging activities of the WhatsApp group created by volunteers after the earthquake in Turkey. During the 7-day period included in the research, a total of 5813 messages were sent. 3472 of these messages were not included in the research for various reasons, and a total of 2341 messages were used for the research. RESULTS: In all 7 days, it was seen that most of the messages were sent via text message and that voice messages were very few. When the distribution of the needs demanded by the earthquake victims for 7 days was examined, it was seen that there was a significant increase in the needs on the fourth day after the earthquake, and that the highest increase was the need for tents. CONCLUSION: While the demands for rescue services increased in the first 2 days, it was determined that the demands for water especially, dry food, and tents increased from the third day onwards. It is suggested that a professional online infrastructure system should be created to enable the transfer of instant scene and need information that can be activated in such disasters.

Psychological Hardiness and Compassion Satisfaction Among the Turkish Red Crescent: The Case of 2023 Kahramanmaras Earthquake.

OBJECTIVES: This study assessed psychological hardiness and compassion satisfaction among the Türk Kizilay (Turkish Red Crescent) personnel and volunteers involved in the 2023 Kahramanmaras earthquake. Additionally, the relationship between compassion satisfaction and psychological hardiness was also investigated. METHODS: This cross-sectional study was conducted between March and July 2023. Participants completed an online survey, which included the Sociodemographic Information Form, Psychological Hardiness Scale, and Compassion Satisfaction Scale. The data was analyzed with SPSS version 25 (IBM Corp., Armonk, New York, USA), using a significance level of 95% and p < 0.05. RESULTS: The study involved 400 participants, comprising 84 (21%) personnel and 316 (79%) volunteers. Participants exhibited an average psychological hardiness level of 24.56 ± 7.25 and a compassion satisfaction level of 47.40 ± 17.28. A significant positive correlation was observed between compassion satisfaction and psychological hardiness (r = 0.571; p < 0.001). The results of logistics regression have revealed that the level of psychological hardiness is higher in males compared to females (OR = 1.930, CI = 1.115 - 3.340; P < 0.05) and is also higher in those with high compassion satisfaction compared to those with low compassion satisfaction (OR = 1.386, CI = 1.256 - 1.529; p < 0.001). CONCLUSIONS: The findings of this study indicate that individuals involved in disaster response should consider compassion satisfaction as an important tool for enhancing psychological hardiness.

Clinical properties and rehabilitation needs of earthquake survivors in a subacute rehabilitation setting.

BACKGROUND: This descriptive analysis examines the victims of the February 6, 2023, earthquakes in Kahramanmaras and Elbistan, Türkiye. It aims to detail the injury profiles related to neuro-musculoskeletal trauma, assess the rehabilitation needs of patients, and propose a comprehensive rehabilitation approach. METHODS: The study included patients injured in the Kahramanmaras-centered earthquake on February 6, 2023, who were transported to our hospital based on their rehabilitation needs. Data from patients treated at our hospital were recorded retrospectively. This included demographic information, accompanying pathologies, laboratory findings, rehabilitation programs, and treatments received during their hospital stay. Statistical analyses were conducted to examine the data. RESULTS: A total of 141 patients with musculoskeletal injuries were admitted due to injuries sustained from the earthquake. The mean age of the participants was 39.76 years, with a slight female predominance (56.7%). The majority of patients sustained injuries while trapped under debris (90.1%), with an average duration of 10 hours under rubble. Fractures were the most common form of injury (53.2%), predominantly affecting the lower extremities. Peripheral nerve injuries were present in 41.1% of patients, and amputations were observed in 30.5%. Complications included compartment syndrome (46.1%), crush syndrome (36.2%), and various infections. Pain was prevalent among patients, with somatic pain being the most reported type. Individualized rehabilitation programs were implemented, incorporating physical therapy, wound care, pain management, and psychosocial support. CONCLUSION: This study highlights the critical rehabilitation needs of earthquake survivors and emphasizes the importance of early and comprehensive rehabilitation interventions. Multidisciplinary rehabilitation programs were crucial in addressing medical issues, functional limitations, and psychological challenges faced by the survivors. The findings contribute to a deeper understanding of earthquake-related injuries and underscore the significance of well-coordinated rehabilitation strategies in disaster responses.

Evaluation of pediatric trauma score and pediatric age-adjusted shock index in pediatric patients admitted to the hospital after an earthquake.

BACKGROUND: In our earthquake-prone country, it is crucial to gather data from regional hospitals following earthquakes. This information is essential for preparing for future disasters and enhancing healthcare services for those affected by earthquakes. This study aimed to evaluate the Pediatric Trauma Score (PTS) and the Shock Index, Pediatric Age-Adjusted (SIPA), in children affected by earthquakes, to provide clinicians with insights into the severity of trauma and hemodynamic stability. METHODS: The study included patients admitted to our hospital's pediatric emergency service within the three weeks following the earthquake. We evaluated their age, sex, admission vital signs, mechanical ventilation requirements, development of crush syndrome, length of hospital stay, PTS, and SIPA. RESULTS: Our study included 176 children (89 females and 87 males) with trauma. Fifty-eight (32.95%) children had crush syndrome, and 87 (49.43%) were hospitalized. The median PTS was 10 (ranging from -3 to 12), and the median SIPA was 1.00 (ranging from 0.57 to 2.10). We observed a negative correlation between the time spent under debris and PTS (r=-0.228, p=0.002) and a positive correlation with the SIPA score (r=0.268, p<0.001). The time spent under debris (p<0.001) and SIPA score (p<0.001) were significantly higher in hospitalized children. PTS was significantly lower in hospitalized children than in others. A PTS cutoff point of 7.5, and a SIPA cutoff point of 1.05, predicted hospitalization in all children. Time spent under debris and SIPA were significantly higher in children with crush syndrome than in others (p<0.001). PTS at a cutoff point of 8.5 and SIPA at a cutoff point of 1.05 predicted crush syndrome in all children. CONCLUSION: PTS and SIPA are important practical scoring systems that can be used to predict the severity of trauma, hospitalization, crush syndrome, and the clinical course in pediatric patients admitted to the hospital due to earthquake trauma.
