We determine rupture kinematics of the 2020 Mw 6.7 Elazig, Turkey earthquake from joint inversion of interferometric synthetic aperture radar (InSAR) measurements, regional 1 Hz Global Navigation Satellite System (GNSS), strong motion, and teleseismic waveforms, and we also use dynamic modeling to assess the faulting properties to explain the observed kinematics. Our work shows that this event predominantly ruptured unilaterally toward 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 Pazarcık seismic gap, it remains elusive to evaluate the disturbed seismic potential between Elazig and Bingol regions.

2020年1月24日土耳其瓦拉兹6.7级地震的运动学和动力学

我们确定2020 M w的破裂运动学6.7土耳其Elazig地震来自干涉合成孔径雷达(InSAR)测量,区域1 Hz全球导航卫星系统(GNSS),强运动和远震波形的联合反演,并且我们还使用动态建模来评估断层特性,以解释观察到的运动学。我们的工作表明,该事件主要沿东安纳托利亚断层带向西南方向单侧破裂,速度低至2.0 km / s,持续约20 s,并且形成了三个主要的凹凸不平,其深度范围为地表20 km,但表面破裂似乎可以忽略不计。此外,动力学模型还揭示了初始非均质应力分布,其变化高达30 MPa,这可能是在地震期间建立的。尽管该事件似乎并未促进Pazarcık地震缝隙的破坏,
