TOKYO — A powerful magnitude 7.6 earthquake shook Japan’s northeast region late on Monday, prompting tsunami warnings and orders for residents to evacuate.
A tsunami as high as three meters (10 feet) could hit Japan’s northeastern coast after an earthquake with an estimated magnitude of 7.6 occurred offshore at 11:15 p.m. (10:15 p.m. Philippines time), the Japan Meteorological Agency (JMA) said.
Tsunami warnings were issued for the prefectures of Hokkaido, Aomori and Iwate, and a tsunami of 40cm had been observed at Aomori’s Mutsu Ogawara and Hokkaido’s Urakawa ports before midnight, JMA said.
The epicenter of the quake was 80 km (50 miles) off the coast of Aomori prefecture, at a depth of 50 km (30 miles), the agency added.
No tsunami threat to PH
In a statement, Phivolcs said there is no tsunami threat to the Philippines. The monitoring agency measured the quake at a 7.6 magnitude, and said that it struck at 10:15 p.m. Philippines time at a depth of 51 km.
The United States Geological Survey (USGS) also measured the quake at 7.6.
Japan is one of the world’s most earthquake-prone countries, with a tremor occurring at least every five minutes.
East Japan Railway suspended some train services in the area, which was also hit by the massive 9.0-magnitude quake in March 2011.
Located in the “Ring of Fire” arc of volcanoes and oceanic trenches partly encircling the Pacific Basin, the country accounts for about 20% of the world’s earthquakes of magnitude 6.0 or greater. — Reuters
