The author proposed a model of plate breakup in the Japan Sea in 1983 (Sun, 1983), and predicted that shallow earthquake of M.7 or over will occur before 1993 off the west coast of Central Japan, from the model of plate breakup and migration of epicenters in the shallow earthquakes in the Japan Sea, at the international symposium in 1987 at Beijing, China (Sun, 1987). The occrrence of the Off Noto Peninsula Earthquake on 7th, Feb. 1993 demonstrated that the medium-term prediction made by the author in 1987 came true. The success of this prediction should provide an impetus to the researches on earthquake prediction elsewhere.
