SEISMIC RISK ASSESSMENT IN THE ATTICA BASIN

Bulletin of the Geological Society of Greece, 2017
This paper aims to determine the exposure-based earthquake risk posed in the Attica Basin, Greece using a GIS based methodology. The hazard level is based on grouped geological formations according to the New Ground Anti-Earthquake Regulation of Greece and the structural setting of the area. Vulnerability is calculated using two different methodologies.
