6.3 magnitude earthquake shakes southern Japan

TOKYO, Sept. 20 (UPI) -- A magnitude 6.3 earthquake struck early Wednesday in the sparsely populated Izu Islands southeast of Japan's main island of Honshu, the Japan Meteorological Agency reported.

The U.S. Geological Survey said the quake was 6.1 and hit around 1:21 a.m. in Japan with its epicenter about 382 miles south-southeast of Tokyo at a depth of 6.2 miles.

The Japan Meteorological Agency said although there might be slight sea-level changes in coastal regions, the earthquake has caused no damage to Japan. No tsunami warnings were issued by the Pacific Tsunami Warning Center.

In April, earthquakes of 6.2 and 7.0 hit Japan on back-to-back days on the southern island of Kyushu.

On Tuesday, Typhoon Malakas, a Category 3 storm, struck southern Japan with destructive winds and flooding.
