A major earthquake struck offshore of Japan Friday, killing hundreds and triggering a tsunami that reached Hawaii, Alaska and the U.S. West Coast.

The magnitude 8.9 earthquake hit just before 3 p.m. local time about 80 miles off the eastern coast of Japan, approximately 230 miles northeast of Tokyo. The quake immediately generated a tsunami.

Tsunami waves reached Hawaii, Alaska and the U.S. West Coast throughout Friday morning. Senior Meteorologist Kristina Pydynowski has details on tsunami wave heights that have been observed and the impacts they've had.

There have been reports that several people were swept out to sea in California and Oregon.

Tsunami warnings and advisories remain in effect for Hawaii, Alaska, California, Oregon and Washington. Please be sure to heed all advice from local emergency management officials!

NOAA also has a list of expected arrival times for tsunami waves.

Earlier Friday, a 23-foot tsunami washed ashore across northern Japan along the Miyagi prefecture, causing devastating damage and washing homes and vehicles well inland.

Farther inland, there are early reports of structural damage and fires, while buildings in Tokyo even swayed from the powerful tremors, sending people fleeing into the streets.

Earlier, Japan's meteorological agency issued tsunami warnings for the Miyagi prefecture, warning that a tsunami as high as 20 feet could strike.

Tsunami warnings are also in effect for many areas across the Pacific rim.
