The US Geological Survey has determined that the tremor that struck about 200 miles east of the island of Honshu this morning had a magnitude of 7.1, although some reports are pegging its strength at 7.3.

Preliminary readings for the quake placed it at 7.5.

Tsunami of a little more than a foot tall were reported reaching Japan’s coast from the tremor which struck at a depth of 6.2 miles at 7:10 a.m., Hawaii time, and 3:10 a.m. Saturday, Oct. 26, local time.

It occurred about 70 miles east-northeast of the 9.0-magnitude March 2011 Tohoku tremor off Japan. That earthquake generated a massive tsunami that caused hundreds of billions of dollars in damage in Japan.
