Interdisciplinary Dating of Utrish Seismic Dislocations: Localization of the Source of a Strong Historical Earthquake in the Western Caucasus

A strong historical earthquake, likely with a magnitude of MW ≈ 6.9, struck the Western Caucasus region between the 12th and 13th centuries, according to an interdisciplinary study combining paleoseismological, archaeological, and dendrochronological evidence. The seismic source was localized in the Utrish Fault zone along the Abrau Peninsula coast, marking a significant contribution to seismic hazard assessments for the area. This finding underscores the seismogenic role of the fault, providing critical insights into the region's tectonic activity and historical earthquake risks.
