New findings on the sources of strong earthquakes in Kerch Peninsula based on paleoseismological data

This paper presents the results of the recent paleoseismological studies covering the entire Kerch Peninsula. The Yuzhnoberezhnaya fold-and-thrust belt extending along the southern coast of Crimea in the Black Sea was earlier considered the principal seismogenic structure. Our findings suggest that the seismic hazard on the Kerch Peninsula is largely related to potential strong onshore earthquake sources. The observed discrepancy between instrumental and paleoseismological data suggests that seismic quiescence exists in this region at present.     

Archeoseismological study in Salachik,the ancient capital of Crimean Khans

Archeological, archeoseismological, and seismotectonic studies were carried out in Salachik, the ancient capital of the Crimean Khans, on the outskirts of the modern city of Bakhchysarai, Crimea. The following damage and deformations of medieval buildings were observed: tilted building walls, shifted elements of building structures, rotation of fragments of walls and building blocks around the vertical axis, considerable deformations of arch structures, and fissures running through several rows of building blocks. These deformations are of a seismogenic nature. Traces of at least two strong ancient earthquakes were revealed in the medieval monuments of Salachik. Based on analysis of kinematic indicators, it is found that the maximum seismic intensity (VIII ≤ I ₀ ≤ IX points) was due to an earthquake occurred in the west. Based on historical seismologic data, one of the two earthquakes is dated by April 30, 1698. Also, structural damage to buildings in Salachik was caused by Crimean earthquakes in 1927. The findings can be used for a comprehensive assessment of seismic hazards on the Crimean Peninsula.

Tectonic position and preliminary data on geological manifestations of the 2011–2012 Tyva earthquakes

The preliminary data on the tectonic position and seismological manifestations of the strong Tyva earthquakes that occurred on December 27, 2011 and February 26, 2012 are reported. The seismic ruptures are studied. The earthquake source structure in the earth’s depths is considered.
