More earthquakes measuring over 7.0 on the Richter scale could occur in and around Japan within a month, the country's National Meteorological Administration was quoted by Kyodo news as saying on Friday.
The death toll from a massive earthquake that hit the north-east of Japan on Friday has reached 23, local TV reported.
The 8.9-magnitude quake that struck about 373 kilometers from the capital Tokyo sparked a tsunami that hit Miyagi and Iwate prefectures, sweeping away houses and cars.
A 10-meter tsunami subsequently hit the Miyagi prefecture on Honshu. Honsu's Iwate prefecture was reported to have been hit by a 4.2-meter tsunami. Dozens of cars fell into the sea when a highway in Iwate was partly destroyed by the quake.
