Two more quakes; one meauring 7.0, as well as a 7 foot tsunami have followed the main temblor.

The quake struck in the Pacific Ocean, about 65 miles south-southwest of Kushiro and 495 miles north-northeast of Tokyo, said John Minsch, a USGS geophysicist. The quake was shallow.

The quake has knocked out power, rocked several buildings, and derailed a local train. Over 120 people have been reported injured.

Fires have been reported in the city of Tomakomai. Plumes of black smoke and flames are seen rising from an industrial area.
