6.2-magnitude earthquake strikes Japan, no tsunami

May 26 (UPI) -- A 6.2-magnitude earthquake on Friday shook eastern Japan, including Tokyo but officials said there were no threats of a tsunami. The Japanese Meteorological Agency said the earthquake happened Friday evening, forcing bullet trains in the Hokuriku, Joetsu and Tohoku Shinkansen lines to stop for about 10 minutes because of a temporary blackout, East Japan Railway Co. said. The epicenter for the earthquake was pinpointed off the coast of Chiba at a depth of about 31 miles. It was the second sizable quake for the region this month. A 5.2 magnitude earthquake also struck the Chiba Prefecture on May 11.
