Abstract: For engineering design and seismic risk assessments, earthquake ground motions are characterized using intensity measures such as peak acceleration or spectral accelerations. Ground motion models (GMMs) estimate statistical distribution of intensity measures given information about the source, source-site path (distance), and site condition. This research extends data resources originally developed for Central America and Mexico for the NGA-Subduction (NGA-Sub) project database and uses the data to provide regional customization of global GMMs for application in Mexico.
