Few studies have compared the sensitivity of trauma questionnaires to disaster inventories for assessing the prevalence of exposure to natural disaster or associated risk for post-disaster psychopathology. The objective of this analysis was to compare reporting of disaster exposure on a trauma questionnaire (Brief Trauma Questionnaire [BTQ]) to an inventory of disaster experience. Between 2011 ...

Road damage detection and assessment from high-resolution remote sensing image is critical for natural disaster investigation and disaster relief. In a disaster context, the pairing of pre-disaster and post-disaster road data for change detection and assessment is difficult to achieve due to the mismatch of different data sources, especially for rural areas where the pre-disaster data (i.e., re...

Four propositions drawn from 60 years of natural hazard and reconstruction research provide a comparative and historical perspective on the reconstruction of New Orleans after Hurricane Katrina. Decisions taken over its 288-year history that have made New Orleans so vulnerable to Katrina reflect a long-term pattern of societal response to hazard events--reducing consequences to relatively frequ...

BACKGROUND Self-efficacy may be an important factor in individuals' recovery from posttraumatic stress reactions after a natural disaster. However, few longitudinal studies have investigated whether self-efficacy predicts the course of posttraumatic recovery beyond lower initial levels of distress. The purpose of the present study was to investigate whether general self-efficacy is related to r...

BACKGROUND Disaster research suggests that immigrant groups who are affected by a disaster receive less emotional support than their native counterparts. However, it is unclear to what extent these differences can be attributed to post-disaster mental health problems or whether they were present before the event. AIMS To examine the association between lack of social support, immigration ...

Definition Disaster recovery. Disaster recovery has three distinct but interrelated meanings. First, it is a goal that involves the restoration of normal community activities that were disrupted by disaster impacts – in most people’s minds, exactly as they were before the disaster struck. Second, it is a phase in the emergency management cycle that begins with stabilization of the disaster cond...

Computational models of natural disasters are invaluable means of disaster reconstruction, crisis management, and disaster prevention. The Medigrid project addressed these issues by developing a framework of simulation models developed in previous projects. The paper describes the models incorporated into the project, together with the visualization service developed for presentation of models’...

This paper proposes a method to reconstruct and visualize landslide events based on pre- post-disaster remote sensing data. The proposed establishes the dynamic equations of evolution process calibrates model parameters Based calibrated equations, we simulate historical evolution. experimental results show that our could dynamically realistically process. Moreover, simulation can also detect ma...

With digital information technology based on limited data, disaster simulation review is an important guideline for analyzing mechanisms, planning post-disaster reconstruction, and improving defense capability. Taking the “7.20” flash flood in Wangzongdian river basin as a research area, hydrological-hydrodynamic model was established using measured data. The results showed that extreme rainsto...
