SHIPUNSKOVE EARTHQUAKE 17.08.2024, M = 7.0, OF THE EAST COAST OF KAMCHATKA

The article presents instrumental parameters and macroseismic data on the Shipunsky earthquake of August 17, 2024, M = 7.0, M = 7.0, discusses its tectonic position and features of the aftershock process, estimated based on the results of the first month of observations after the main event. The mechanisms and parameters of the Shipunsky earthquake sources and its strongest aftershocks are presented, obtained using the original method for calculating seismic moment tensors developed at the KB FRC EGS RAS. The direction of movement and the orientation of the rupture planes in the sources of these events allow us to attribute their occurrence to the subduction of the Pacific plate under the Okhotsk plate, on which Kamchatka is located. The Shipunsky earthquake did not cause casualties or damage. Its maximum macroseismic manifestation was observed at Cape Shipunsky, 6 points on the SSI–17 scale (GOST R 57546–2017); in Petropavlovsk-Kamchatsky, the intensity of the tremors was 5–6 points. No tsunami alarm was declared, and no tsunami waves were recorded.
