Japan earthquake creates powerful aftershocks

TOKYO (AP) - Aftershocks of at least 7.9-magnitude have been hitting Japan after an 8.9-magnitude earthquake struck off Japan's northeastern coast, shaking buildings in Tokyo for several minutes and sending people out into the streets.

Japan's meteorological agency warns that a tsunami as high as 20 feet could strike the coast near Miyagi prefecture, closest to the epicenter. Early Friday morning, local television showed dramatic pictures of large waves hitting the coastline.

The agency says the quake struck at 2:46 p.m. Friday at a depth of 6 miles, about 80 miles off the eastern coast.

Several quakes had hit the same region in recent days, including a 7.3 magnitude one on Wednesday.
