Landslides on the Eastern Slope of Sakhalin Island as Possible Tsunami Sources

摘要

An underwater landslide located in the central part of the eastern slope of Sakhalin Island was found and mapped during investigations under the auspices of the Korean—Russian Project Sakhalin Slope Gas Hydrates (SSGH) [1, 2]. The study region was confined to a depression oriented in the northeasterly direction (Fig. la). The research in this region [1—4] demonstrated that closed depressions with round and slightly elongated forms in the northeasterly direction are characteristic peculiarities of the morphology of this depression (Fig. 1b).
