Seismic Hazard Assessment of the Tehran Region

Abstract

The region around Tehran is considered a high seismicity area. It should arouse more concern to the seismic safety of this city given that the last damaging earthquake occurred nearly 200 years ago, and the geotechnical condition in the study area possibly could cause site amplification. Therefore, this study presents a new hazard map for the region around Tehran with deterministic seismic hazard analysis. In addition, a procedure to select earthquake time histories is demonstrated. From seismic hazard estimates, to site effect, to engineering risk mitigation, some discussions about earthquake designs and land uses for Tehran also are given in this paper.
