Source mechanism and rupture propagation in the Mudurnu Valley, Turkey, earthquake of July 22, 1967
- 52 Downloads
First motions ofP waves and amplitude spectra ofG2 andG3 waves have been used to determine the source mechanism and rupture propagation. The amplitudes ofG3 waves have been corrected for the attenuation using aQ-model obtained from the amplitude spectra ofG2 andG3 waves. Observed directivities for the strike-direction agreed with a model of a bilateral fault propagated primarily from east to west.
