Submarine Landslides in the Sea of Okhotsk

The distribution map of submarine landslides in the Sea of Okhotsk based on compilation of available data is presented in this work for the first time. This map is indicative of environments and trigger mechanisms of landsliding. All gravitational processes studied in this work occurred in the environments of an open continental slope and submarine canyons. The most obvious trigger mechanisms of landslides on the Eastern Sakhalin slope are seismic activity and gas seeping. The main trigger mechanism of landslides on the northern slope of the Kuril Basin and in the back-arc basin of the Kuril island arc is seismic activity.
