An earthquake with a preliminary magnitude of 4.8 struck Tokyo, Kanagawa Prefecture and surrounding areas Sunday morning. The meteorological agency said that although the quake at 8:59 a.m. reached a maximum score of 4 on the Japanese seismic scale in central Tokyo, other parts of the capital and Yokohama, there was no tsunami threat. The epicenter of the quake was in Tokyo Bay at a depth of 80 kilometers.
According to NHK, the quake did not seem to affect train service on the Tokyo Metro, with JR East and private rail operators reporting that trains were operating unchanged. However, reports indicate that at least one shinkansen traveling between Shinagawa station in Tokyo and Shin-Yokohama station in Kanagawa Prefecture made an emergency stop around 9 a.m.
