TOKYO - Two strong earthquakes with preliminary magnitudes of 4.6 and 6.9 rocked Japan in quick succession Sunday. There were no immediate reports of damage or injuries.
The larger of the two was centered 255 miles below the seabed off the coast of Hokkaido, Japan's northernmost island, the Meteorological Agency reported.
The temblor was felt throughout the eastern part of Hokkaido as well as in neighboring Aomori prefecture (state).
Seven minutes earlier, a fairly strong quake shook in Ishikawa and Toyama prefectures in central Japan. Described as "quite shallow" by the agency, it was felt in a number of small towns in the Kaga region of Ishikawa.
