The boundary between Okhotsk Plate and Amurian Plate might be responsible for many strong earthquakes that occurred in the Sea of Japan as well as in Sakhalin Island , such as the MW7 .1 ( MS7 .5 according to other sources ) earthquake of May 27 , 1995 in northern Sakhalin . The earthquake devastated the town of Neftegorsk , which was not rebuilt afterwards . Other notable intraplate earthquakes , such as the 1983 Sea of Japan earthquake and the 1993 Hokkaidō earthquake , have triggered tsunamis in the Sea of Japan
