Earthquakes, an Epidemiological Perspective on Patterns and Trends

The unpredictable nature of earthquakes and the vast impact they can have makes them one of the most lethal kinds of natural disaster. Earthquakes have claimed an average of 27,000 lives a year since 1990, according to the data on reported deaths compiled by the EM-DAT International Disaster Database, which is maintained by the Centre for Research on the Epidemiology of Disasters (CRED) at the Catholic University in Louvain, Belgium. The consequences of earthquake disasters vary around the globe, depending on the region and its economic development. Data shows that the number of earthquakes causing significant human and economic loss has increased since the 1970s, endorsing research into individual risk patterns which can provide important information for community-based preparedness programmes. Epidemiological analysis of earthquake impact data can be useful for evaluating impact patterns over space and time. However, the lack of standard definitions of exposure to risk of death or injury from earthquakes is an ongoing methodological obstacle and contributes to inaccuracies in calculations of rates and ratios for comparison purposes. Standardised definitions of deaths and injuries from disasters would improve understanding of earthquake-related risks.

Measuring psychological resilience to disasters: are evidence-based indicators an achievable goal?

Despite rising interest on the concept of societal resilience and its measurement, little has been done to provide operational indicators. Importantly, an evidence-based approach to assess the suitability of indicators remains unexplored. Furthermore few approaches that exist do not investigate indicators of psychological resilience, which is emerging as an important component of societal resilience to disasters. Disasters are events which overwhelm local capacities, often producing human losses, injury and damage to the affected communities. As climate hazards and disasters are likely to increase in the coming decades, strengthening the capacity of societies to withstand these shocks and recover quickly is vital. In this review, we search the Web of Knowledge to summarize the evidence on indicators of psychological resilience to disasters and provided a qualitative assessment of six selected studies. We find that an evidence-based approach using features from systematic reviews is useful to compile, select and assess the evidence and elucidate robust indicators. We conclude that strong social support received after a disaster is associated with an increased psychological resilience whereas a female gender is connected with a decrease in the likelihood of a resilient outcome. These results are consistent across disaster settings and cultures and are representative of approximately 13 million disaster-exposed civilians of adult age. An approach such as this that collects and evaluates evidence will allow indicators of resilience to be much more revealing and useful in the future. They will provide a robust basis to prioritize indicators to act upon through intersectoral policies and post-disaster public health interventions.

Quantifying global and environmental change impactsMethods, criteria and definitions for compiling data on hydro-meteorological disaster

The world is confronted with the impact of natural disasters on human lives and livelihoods on a tremendous scale. These disasters affected 184 million people globally each year, on average, between 1980 and 2008, with a range of 28 million to 661 million. The annual loss of nearly 74,000 human lives occurred on average during this same period, with a range of 10,000 to 460,000. During 2008, 1 out of 31 persons worldwide was affected by natural disasters. Climaterelated disasters caused 45,000 deaths each year and affected 178 million people, on average, between 1980 and 2008.

As climate hazards and disasters are likely to increase in the coming decades, strengthening the capacity of societies to withstand these shocks and recover quickly is vital. Objectives To review the evidence on indicators of psychological resilience to disasters. Methods A literature review using the Web of Knowledge was conducted. We examined 58 references identified through our search, which included predefined key terms and a search strategy along with clear inclusion and exclusion criteria. Six studies were included in this work. Result We provided a qualitative assessment of six selected studies. We find that an evidence-based approach using features from systematic reviews is useful to compile, select and assess the evidence and elucidate robust indicators.
