Japan Lifts New Tsunami Warning

UPDATE: Officials have lifted a tsunami warning for the coast of Japan, 90 minutes after a major earthquake struck offshore. The quake off northeastern Japan had prompted a warning for a wave up to 6 feet in the same coastal area devastated by last month's tsunami. The aftershock shook buildings and knocked out power, but no major damage has been reported.

Officials evacuated two workers at the nuclear power plant damaged in last month's quake and tsunami, and seven at a sister plant to the south. But they say there's no sign of any new problems.

Today's aftershock was centered at about the same location and depth as last month's 9.0 quake. Japanese officials said today's quake was a 7.4, while the U.S. Geological Survey in Golden, Colo., measured it at 7.1.

UPDATE: U.S. officials say a 7.4-magnitude earthquake off the coast of Japan is not expected to create a tsunami threat in Hawaii or the West Coast. Federal agencies say that area includes Hawaii, California, Oregon, Washington, Alaska and British Columbia, Canada. No tsunami warning, watch or advisory is in effect for these areas.

The Japan meteorological agency issued a tsunami warning for a wave of up to about 3 feet. The warning was issued for a coastal area of Japan already torn apart by last month's tsunami.

Buildings as far away as Tokyo shook for about a minute. Hundreds of aftershocks have shaken the northeast region devastated by the March 11 earthquake, but few have been stronger than 7.0.

UPDATE: Officials at Japan's damaged nuclear power plant say there are no signs of new damage there from a strong aftershock today.

The magnitude 7.4 aftershock off of northeastern Japan prompted a tsunami warning for a wave up to 6 feet, in a coastal area already torn apart by last month's tsunami.

Announcers on Japan's public broadcaster NHK told coastal residents to run to higher ground.

Last month's quake and tsunami are believed to have killed some 25,000 people. The disaster sparked an ongoing crisis at a nuclear power plant.

But officials at the plant say they aren't seeing any additional problems. They say they evacuated two workers there and seven at a sister plant to the south.

Officials say today's aftershock hit 16 miles under the water. An earthquake monitor in Colorado says it happened at about the same location and depth as last month's quake, which was a 9.0-magnitude. Buildings as far away as Tokyo shook today for about a minute.
