TOKYO, Sept. 23 (UPI) — A 6.2-magnitude earthquake struck about 80 miles off the east coast of Japan at a depth of about 6 miles on Friday, the U.S. Geological Survey reported.
The Japanese city nearest to the quake is Katsuura with a population of about 22,300. The Pacific Tsunami Warning Center did not issue a tsunami warning related to the earthquake.
The USGS said there have been at least 10 aftershocks in the wake of the temblor, measuring from magnitudes of 4.5 up to 5.3.
Friday’s earthquake follows a 6.3-magnitude that occurred early Wednesday in the sparsely populated Izu Islands southeast of Japan’s main island of Honshu. On Tuesday, Typhoon Malakas, a Category 3 storm, struck southern Japan with destructive winds and flooding.
