Description:

The GSHAP was implemented in the 1992-1999 period, with the support of international projects and organizations, of national scientific agencies and research institutions. More than 500 scientists devoted their time, knowledge and strength to this international endeavour. In order to mitigate the risk associated to the recurrence of earthquakes, the GSHAP promoted a regionally coordinated, homogeneous approach to seismic hazard evaluation. To achieve a global dimension, the GSHAP established initially a mosaic of regions and multinational test areas, then expanded to cover whole continents and finally the globe. The GSHAP Global Seismic Hazard Map was compiled by joining the regional maps produced for different GSHAP regions and test areas. It depicts the global seismic hazard as Peak Ground Acceleration (PGA) with a 10% chance of exceedance in 50 years, corresponding to a return period of 475 years.
