Kinematics and dynamics of the January 24, 2020 Mw 6.7 Elazig, Turkey Earthquake

2020 
We determine rupture kinematics of the 2020 M_w 6.7 Elazig, Turkery earthquake from joint inversion of InSAR measurements, regional 1 Hz GNSS, strong motion and tele‐seismic waveforms, and we also use dynamic modelling to assess the faulting properties to explain the observed kinematics. Our work shows that this event predominantly ruptured unilaterally towards the SW along the East Anatolian Fault Zone at a speed as slow as 2.0 km/s for ~20 s, and three main asperities are formed with a depth ranging from 20 km to the surface, but the surface rupture seems negligible. Besides, the dynamic model reveals an initial heterogeneous stress distribution with variations up to 30 MPa, which has been probably built up during the interseismic period. While this event does not seem to promote the failure of Pazarcik seismic gap, it remains elusive to evaluate the disturbed seismic potential between Elazig and Bingol region.
