Catastrophic geomorphic processes in the coastal regions west of the Sea of Okhotsk

Abstract

Geology, topography and climate of the area under consideration contribute to high concentration of extreme geomorphic processes. Most hazardous and most important for the relief formation are earthquakes which induce seismic rockfalls, debris falls and landslide activation. Other catastrophic events are related to monsoon floods and autumn storms, often accompanied by storm surges and resulting in accelerated marine erosion. The land use in the area must be under strict control.
