Crimean Mountains; Slope deformation; Dendrogeomorphology; Crimean pine; Earthquake; Mass movement

The Crimean Mountains in ukraine constitute a seismically active region that is abundant in various types of mass movement. The limestone escarpments that rise above the Black Sea coast in the vicinity of the town of Yalta are particularly subject to considerable rockfall, landslide and debris flow processes that often endanger infrastructure and human life. The aims of this study were (i) to employ tree-ring analysis to reconstruct a record of slope instabilities (mainly block-type movement, rockfall, landslide and debris flows) within the Taraktash slope deformation over a period of more than two centruries and (ii) to establish the degree of correlation between periods of enhanced slope activity and both historical earthquake.
