Tsunami warning issued but later lifted.

TOKYO -- A 6.7-magnitude quake struck 30 miles off the coast of Iwate Prefecture in Japan’s northeast, just before 7 a.m. Thursday local time, shaking buildings in Tokyo, 300 miles away.

Emergency earthquake alerts went out on pubcaster NHK and other channels.

A tsunami warning was also issued but lifted at 7.45 a.m.

No damage was reported at the stricken Fukushima Dai-ichi Nuclear Plant, or the other nuclear facilities that lie closer to the epicenter, which was 12 miles below the seabed.

The temblor brought bullet-trains to a halt in the northeast but no damage was reported in the areas devastated by the March 11 mega-quake and tsunami.
