Japan earthquake today measuring 8.5 magnitude strikes near Ogasawara islands


An earthquake with a magnitude of 8.5 struck near the Ogasawara islands at 8:24 p.m. Saturday, Japan Meteorology Agency (JMA) reported.

The earthquake shook buildings in Tokyo and temporary closed both runways at Narita Airport. According to NHK, train service between Tokyo and Osaka was halted due to a power outage.

The U.S. Geological Survey downgraded the magnitude to 7.8 with epicenter located 189 km WNW of Chichi-shima.

According to the U.S. Geological Survey, Japan earthquake today occurred as the result of oblique-normal faulting at a depth of over 660 km beneath the Pacific Ocean. This earthquake occurred in response to stresses generated by the slow distortion of the Pacific plate at depth, rather than occurring on the interface between the Pacific plate and the overriding Philippine Sea plate.

The earthquake had maximum intensity of 5 in the Ogasawaras. A tsunami warning has not been issued. The earthquake was so deep, the aftermath may be limited, The Huffington Post mentioned.

There were no immediate reports of significant damage or injuries, though the Tokyo Fire Department had received calls of people suffering injuries through falls, The Japan Today reported quoting the NHK national television.

Magnitude 9.0 earthquake off the Pacific coast of Tohoku in 2011 had triggered powerful tsunami waves killing more than 15,000 people.
