An earthquake measuring 6.3 magnitude on the Richter scale struck off the western coast of the Ogasawara Islands in the Pacific Ocean, south of the Japanese capital, Tokyo, on Monday. Japan Meteorological Agency said that the epicenter of the quake was at a depth of 530 km, measuring 3 on the Japanese seismic intensity scale of 7 in Ogasawara Village. With no tsunami threat from the earthquake, there were no immediate reports of injuries or damage. Japan is located at the meeting point of four tectonic plates, making it particularly vulnerable to seismic activity. It is also home to 100 active volcanoes. In 2011, a 9.0-magnitude earthquake rocked Japan and triggered a tsunami, killed more than 15,000 people, and caused a disaster at Fukushima nuclear plant. Source: Qatar News Agency
