Strong Motion Database for Crustal Earthquakes in Greece and Surrounding Area

An updated Hellenic database of strong ground motion recordings together with the earthquake source properties and the site characterization of the recording stations are described here. The strong motion database consists of 2751 corrected recordings from 497earthquakes of focal depths h4.5and a number of finite fault plane solutions corresponding to earthquakes with M>6.0. The data is compiled from existing catalogs published by Hellenic and international seismological centers. The properties for each recording station include surface geology, a measured or estimated time-averaged shear wave velocity in the upper 30m (VS30), and information on instrument housing. Out of the 338sites, 75 have in-situ shear wave velocity measurements while for the rest VS30 values are derived from proxy-based relationships based on terrain or geology combined with surface gradient.
