Type: article
Abstract: The article presents instrumental and macroseismic data on the earthquake of February 13, 2025, with the epicenter in the Krasnodar territory (16 km from Sochi) at 12:12, with h=11 km, Mw=4.1. The earthquake occurred near the epicentral zone of two felt earthquakes that occurred on January 11, 2025 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. Source spectra were calculated based on the records of regional seismic stations of the GS RAS and the spectral parameters of the studied source were determined. The focal mechanism was constructed, according to which the type of movement is a strike-slip with reverse fault components. Macroseismic data collection was carried out, the maximum observed intensity in the village of Solokhaul, the closest settlement to the instrumental epicenter, scored 4–5 on the MSK-64 scale.
