抄録	A large earthquake occurred to the south of Cape Erimo, Hokkaido, at about 9 h 49 m (JST) on May 16, 1968, and severely shook the Tohoku and Hokkaido areas. According to the Japan Meteorological Agency, the epicenter of this shock is 40°7N, 143:7E and 20km depth, and the magnitude 7.8 on the Richter scale. After about ten hours of this main shock, the largest aftershock (M=7.4) occurred at the location 41°4N, 143°3 E and 20km depth. Recently, the southern part of Hokkaido was rocked by two huge earthquakes, one was the Off-Tokachi earthquake of March 4, 1952 (M=8.1), and the other the Off-Hiroo earthquake of April 23, 1962 (M=7.0) (cf. Figure 1).
