Description
When evaluating the seismic hazard within a region or site of interest (e.g., a densely populated city or a nuclear power plant), it is essential to realistically model the characteristics (size, geometry and surface orientation) of large earthquake ruptures that may occur. The GEESE algorithm retrieves sufficiently representative ruptures for queried earthquakes from seismic hazard models developed within the OpenQuake Engine seismic hazard software.
We used the GEESE algorithm to retrieve finite ruptures for the strongest events included in the global-coverage ISC-GEM earthquake catalogue (covering a time window of 1904 to 2019), which we present here as the GEESE database. For each event to which a rupture could be retrieved, the database also included the inputs for an OpenQuake Hazard Scenario calculation and the ground-motion fields (GMFs) computed using some (reconfigurable) default parameters.
