The 24 January 2020 Mw 6.7 earthquake in eastern Turkey was due to the reactivation of the strike‐slip faulting between the Arabian and Anatolian plates. To gain insight into the source regime and its relationship with historical earthquakes, we determined the coseismic slip distribution of this event by joint analyses of Interferometric Synthetic Aperture Radar and teleseismic observations. Inversion results indicate that the main rupture asperity occurred in the southwest of the epicenter with a maximum slip of ∼1.9 m⁠, showing a bilateral source process with an average rupture velocity of ∼1.6 km/s⁠, and small slip extended to the surface near the epicenter. The estimated seismic moment is 1.4×1019 N·m⁠, associated with a ∼50 km long and ∼15 km wide fault plane. The aftershocks distribution is obviously complementary with the coseismic rupture zone. That is, the majority of aftershocks clustered in the transitional regions from the large to small slip areas. The 2020 earthquake only ruptured part of the locked zone and could increase the seismic activity in the East Anatolian fault zone during the interseismic phase. Two verified seismic gaps remain unbroken and hazardous.

2020年1月24日土耳其安纳托利亚东断裂带6.7级兆瓦地震的震源过程

土耳其东部2020年1月24日发生的6.7级地震是由于阿拉伯板块与安那托利亚板块之间的走滑断层恢复活动所致。为了深入了解震源制度及其与历史地震的关系，我们通过干涉合成孔径雷达和远震观测的联合分析确定了该事件的同震滑动分布。反演结果表明，主要破裂隆起发生在震中西南部，最大滑移量约为1.9m⁠，显示出双边破裂过程，平均破裂速度为〜1.6 km /s⁠，小滑移扩展到了地面在震中附近。估计的地震矩为1.4×1019 N·m⁠，与约50 km长和约15 km宽的断层面有关。余震分布与同震破裂带明显互补。也就是说，大多数余震集中在从大滑移区到小滑移区的过渡区域。2020年地震仅使锁定区的一部分破裂，并可能在地震之间增加东安纳托利亚断层带的地震活动。两个经过验证的地震缝隙仍然完整且危险。
