Earthquakes on the south-west of Koryak highlands are connected with a block-key tectonics of lithosphere of marine transital of north-eastern margin of Eurasia and the block-key structure of its strata. The cloud of shocks of three strong earthquakes: Koryak`s (13.10.1988), Khailin`s (8.03.1991) and Olutor`s (20.04.2006) is located over the downfold of lithosphere bottom with drop of depths equal to 15-20 km. Preparation for the seismic events evolution to the north-eastward is possible.
