An earthquake of magnitude 7.3 struck early Saturday off Japan’s east coast, the U.S. Geological Survey said, and Japan’s emergency agencies issued a tsunami advisory for the region that includes the crippled Fukushima nuclear site.
Tsunamis of up to 15 inches were reported at four areas along the coast, but the advisory was lifted less than two hours after the quake.
There were no immediate reports of damage on land. Japanese television images of harbors showed calm waters. The quake hit at 2:10 a.m. Tokyo time about 170 miles off Fukushima, and it was felt in Tokyo, some 300 miles away.
Japan’s meteorological agency issued a 3-foot tsunami advisory for a long stretch of Japan’s northeastern coast, and it put the quake’s magnitude at 7.1. The U.S. Pacific Tsunami Warning Center did not post warnings for the rest of the Pacific.
Worried Japanese regulators met with Tokyo Electric officials this week to discuss how to prepare for a typhoon that could dump heavy rain on Fukushima on Saturday. And Nuclear Regulation Authority Chairman Shinichi Tanaka has scheduled a Monday meeting with Tokyo Electric’s president to seek solutions to what he says appear to be fundamental problems.
