It was the same area of the Pacific where a massive magnitude-9 quake hit on March 11, triggering a deadly tsunami. The Japan Meteorological Agency issued a tsunami warning for Iwate Prefecture but canceled it about an hour later. There were no immediate reports of damage or injuries in the quake that hit at 6:50am local time. It hit offshore from Honshu island, about 325 miles northeast of Tokyo.
