Earthquake on January 12, 2025 at 14:49 in the Black Sea (in the Kerch Peninsula area), Mw=4.2, I0=3-4 points

Instrumental and macroseismic data are presented on two earthquakes that occurred on January 11, 2025, with epicenters in Krasnodar Krai (11 km from Sochi) at 01:47 and 17:43 with h=11 km Mw=3.0 and Mw=3.2, respectively. The earthquake parameters were determined based on instrumental data at the Central Branch of the GS RAS (Obninsk). The studied earthquakes occurred in the southwestern part of the Greater Caucasus structures in the Sochi-Krasnopolyanskaya zone within the Monastyrskaya zone of the ESZ with Mmax=6.0–6.5. Source spectra were calculated based on records from regional seismic stations of the GS RAS and spectral parameters were determined. Macroseismic data collection was carried out; the maximum intensity in the village of Verkhniy Yurt, the closest to the instrumental epicenter, was 4 points on the MSK-64 scale.
