| | Abstract | | Microtremor array explorations were conducted in Damascus, Syrian Arab Republic, to know S-wave velocity profiles of shallow soils for providing fundamental materials in seismic hazard estimations. In this paper, we briefly introduced historical records on earthquakes with damage in Syria. The measurements of microtremors conducted at 32 sites in the city by deploying temporary array with 7 vertical sensors having a station spacing less than 40 meters. Rayleigh-wave phase velocities at periods less than 0.5 second were extracted with processing array data. The phase velocity at each site was inverted to a 1D S-wave velocity profile of soils down to several ten meters. The top S-wave velocity in an area covered with Quaternary layers is about 200m/s with a thickness of less than 20 meters. The depths to the engineering bedrock having an S-wave velocity of about 700m/s are 10 to 80 meters in the city. |
