Ground motions

This tool will estimate the Intensity, Peak Ground Acceleration or Peak Ground Velocity from an earthquake source. In order to use this tool it is necessary to have previously loaded one grid with topography (can have or not bathymetry in it). A second step before use is to draw a trace fault in that map. That is accomplished with “Elastic deformation -> Draw Fault” option as explained also bellow. This tool uses the algorithm from: David J. Wald and Trevor I. Allen. Topographic Slope as a Proxy for Seismic Site Conditions and Amplification. Bulletin of the Seismological Society of America; October 2007; v. 97; no. 5; p. 1379-1395; DOI: 10.1785/0120060267
