The Global Economic Vulnerability Map is a composite index that was designed primarily to measure the potential for economic losses from earthquakes due to a country’s macroeconomic exposure. This index is also an appraisal of the ability of countries to respond to shocks to their economic systems. Relevant indicators include the density of exposed economic assets such as commercial and industrial infrastructure. Metrics used to measure the ability of a country to withstand shocks to...

The Recovery/Reconstruction Potential Map is closely aligned with the concept of disaster resilience. Enhancing a country’s resilience to earthquakes is to improve its capacity to anticipate threats, to reduce its overall vulnerability, and to allow its communities to recover from adverse impacts from earthquakes when they occur. The measurement of recovery and reconstruction potential includes capturing inherent conditions that allow communities within a country to absorb impacts and cope with a damaging earthquake event, such...
The Global Social Vulnerability Map is a composite index that was developed to measure characteristics or qualities of social systems that create the potential for loss or harm. Here, social vulnerability helps to explain why some countries will experience adverse impacts from earthquakes differentially where the linking of social capacities with demographic attributes suggests that communities with higher percentages of age dependent populations, homeless, disabled, under-educated, and foreign migrants are likely to exhibit higher social...
The Global Earthquake Model (GEM) Seismic Hazard Map depicts the geographic distribution of the Peak Ground Acceleration (PGA) with a 10% probability of being exceeded in 50 years, equivalent to a return period of about 475 years, the internationally agreed reference for building safety regulation. The map was created by collating maps computed using national and regional probabilistic seismic hazard models developed by various institutions and projects, and by scientists working at the GEM Foundation....

The OpenQuake Engine is an open source application that allows users to compute seismic hazard and seismic risk of earthquakes on a global scale. It runs on Linux, macOS and Windows, on laptops, workstations, standalone servers and multi-node clusters.
