A 6.7-magnitude earthquake off of Japan's pacific coast struck at about 21:50 UTC or early Thursday in Japan. A tsunami warning was quickly issued due to the quake but later canceled about an hour later.Japanese and U.S. meteorologist agencies detected the earthquake and located the epicenter to be about 330 miles (530 km) north-east of Tokyo.
According to CNN.com, 8,000 people from the cities of Kamaishi and Ofunato, coastal cities, were ordered to evacuate and so far there have been no reported deaths or injuries.
This tremor may have been generated as an aftershock of the quake that hit Japan in March which killed 23,000, although this statement is yet to be confirmed.
