Deep 7.0 magnitude quake strikes off Japan; no tsunami
A magnitude 7.0 earthquake struck on Sunday near Japan's remote Ogasawara Islands, approximately 1,000km south of Tokyo. The Japan Meteorological Agency recorded the event at 11:10 am local time but confirmed there was no tsunami threat, attributing the lack of a wave to the quake's immense depth of 470km.
On the two inhabited islands of the group, Chichijima and Hahajima, the tremor registered a 3 on Japan's 7-point seismic intensity scale. Despite the epicentre's distance from the mainland, shaking was felt across a wide area of eastern and north-eastern Japan as seismic waves travelled efficiently through the Pacific tectonic plate.
The region is highly active, situated where the Pacific plate moves beneath the Philippine Sea plate. Japan sits at the confluence of four tectonic plates, accounting for roughly 10% of the world's earthquakes of magnitude 6 or greater.
