Tsunami Warning As Strong Quake Hits Northern Japan

Japan issued a tsunami warning on Wednesday after a 6.8 magnitude earthquake struck off its northeastern coast, warning of a wave as high as 50 centimetres (20 inches). The meteorological agency gave the tsunami warning after the tremor hit some 210 kilometres (130 miles) off the northern island of Hokkaido. But US monitors said there was no Pacific-wide tsunami threat.



TOKYO (AP) -- A strong earthquake has shaken northern Japan, and regional tsunami advisories have been issued.

The Japan Meteorological Agency said Wednesday evening's earthquake was 6.8 preliminary magnitude off the coast. A tsunami of about a half-meter was expected for Aomori and Iwate prefectures.

Iwate was in the region heavily damaged by last year's earthquake and tsunami.

The epicenter was about 146 miles (235 kilometers) south of Kushiro, Japan, on Hokkaido, Japan's northern island. It was a relatively shallow 16 miles (26 kilometers) from the ocean floor.

The Pacific Tsunami Warning Center in Hawaii said there was no threat there or across the Pacific.
