Ground Truth Events with Source Geometry in Eurasia and the Middle East

Abstract

In this project, Ground Truth (GT) 5 level seismic events in the Middle East and East Africa have been identified and a range of source properties for these events have been determined. The empirically based GT criteria developed by Boomer et al. (2010, 2013) has been used to identify 15 new GT5 events in Saudi Arabia, 5 in Ethiopia, and 10 in Tanzania with magnitudes of 3 or greater. Source parameters were obtained through moment tensor inversions for a number of the events where available waveforms were of sufficient quality. In addition, other source properties, such as seismic moment, stress drop, and corner frequency were also obtained for these events using the Andrews (1986) method. In total, given the quality of available data, we were able to obtain source parameters and other source properties for 8 events in Saudi Arabia, 3 in Tanzania, and 3 in Ethiopia.
