Strong earthquake jolts Japan, no tsunami warning

Magnitude 7.0 earthquake hit eastern and northeastern Japan.

SINGAPORE: A strong earthquake with a magnitude of 7.0 jolted eastern and northeastern Japan on Sunday, but there were no immediate reports of injuries or damages and no tsunami warning was issued. 

The earthquake measured 4 in central Tokyo, Fukushima and their surrounding areas on the Japanese intensity scale, which measures ground motion, according to Japan Meteorological Agency, which uses a different measuring system than the US Geological Survey.

A spokesman for Tokyo Electric Power said there were no reports of any abnormalities at the tsunami-crippled Fukushima Daiichi nuclear plan following the quake.

Some high-speed train services in northern Japan were suspended after the earthquake, but soon resumed operations, Kyodo news reported.

The 7.0 magnitude earthquake, at a depth of nearly 217 miles, was recorded off Japan's southeastern Izu islands on Sunday at 0527 GMT, the US Geological Survey reported.

The Hawaii-based US Pacific Tsunami Warning Center has not issued a tsunami warning following the earthquake located south-southwest of Hachijo-jima in the Izu islands.

Earthquakes are common in Japan, one of the world's most seismically active areas. The country accounts for about 20 percent of the world's earthquakes of magnitude 6 or greater.

On March 11, 2011, the northeast coast was struck by a magnitude 9 earthquake, the strongest quake in Japan on record, and a massive tsunami, which triggered the world's worst nuclear crisis in 25 years since Chernobyl.

The disaster left up to 23,000 dead or missing.
