Site-specific analysis of strong motion data from the September 7, 1999 Athens, Greece earthquake

摘要

The strong ground motion from Athens, Greece 07/09/1999 earthquake has been recorded by eighteen (18) stations, fourteen (14) within the central Athens area and four (4) at the centers of nearby towns. The ground conditions for most of the recordingsites were identified, based on previous geotechnical investigations carried out in the wider area of the sites, and consequently correlated to the seismic motion characteristics. Hence, it has been possible to evaluate the accuracy of different seismological methods for site characterization and also estimate soil effects on peak ground acceleration and elastic response spectra. In addition, preliminary estimates are drawn for the seismic motion characteristics at the epicentral area, where no strong motion recordings are available. The detailed soil profiles at the recording sites are placed in the Appendix.
