Abstract

In the border zone of Kamchatka krai and the Chukotka Autonomous Okrug, an earthquake occurred on January 9, 2020, with M_S = 6.6 (M_W = 6.4) and an intensity at the epicenter of 9–9.5. The seismotectonic position of the source and nature of its seismogenic movement have been preliminarily determined. The seismic history of the region is considered, and the features of the aftershock process are characterized. Seismotectonic and seismological data on this event were acquired. A conclusion is drawn about the propagation of seismic activity to the northeast along the Khatyr–Vyvenskaya active fault zone in the period of 1991–2020. The earthquake was well predicted in the medium term.

Koryak地震：成功预测地震事件的一个例子

摘要

在堪察加边疆区和楚科奇自治区的边界地区，2020年1月9日发生地震，M _S = 6.6（M _W = 6.4），震中烈度为9-9.5。震源位置及其震源运动的性质已经初步确定。考虑该地区的地震历史，并描述了余震过程的特征。获取了有关该事件的地震构造和地震数据。得出的结论是，1991年至2020年期间，地震活动沿Khatyr-Vyvenskaya活动断层带向东北传播。从中期来看，地震是很好的预测。
