Earthquakes can have adverse impacts that extend beyond physical damage or casualties and can severely damage economies and negatively influence societies and social well-being. The addition of the Social Vulnerability component into GEM’s scientific framework provides the means to analyze and better understand the various socio-economic factors that may exacerbate the impact of an earthquake, or that may affect the ability of communities to fully recover from damaging earthquake events. The global modelling of socio-economic vulnerability consists of three maps that depict spatially varying characteristics that affect the impact and recovery potential of populations from damaging earthquakes.
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...
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...

Reconstruction and Recovery
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...
