The Koryak Earthquake: an Example of a Successfully Predicted Seismic Event

In the border zone of Kamchatka krai and the Chukotka Autonomous Okrug, an earthquake occurred on January 9, 2020, with MS = 6.6 (MW = 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.
