Seismic effect of the Bekaa valley fault on the city of Damascus and it is country side

Abstract

In this research, the characteristics of the wave phase's propagation of earthquakes caused by faults. in the Lebanese Bekaa region and the effect of the geological structures through which these seismic waves pass and are recorded in the stations of the National earthquake Center that located in Damascus and its countryside were studied.

The energy spectrum calculation was used to determine the mutual influence between subsurface structures and seismic signals and their reflection on the control of specific period or amplification factor or attenuation of the signal. We conclude from the results to a difference in the energy spectra of the wavelength phases in the seismic records of earthquakes, according to the difference in their location between those areas, according to the difference in the paths of the seismic waves and the locations of the seismic monitoring stations.

Knowing the seismic characteristics of the different sites and paths of seismic waves from the seismic source in the Lebanese Bekaa to the Damascus basin and its countryside where the monitoring stations are located will contribute the seismic hazard mitigation studies that come from the Lebanese Bekaa.
