2015 Ogasawara earthquake is an earthquake caused on May 30, 2015. A magnitude 7.8 earthquake struck offshore of Japan 189 km (117 mi) west northwest of Chichi-jima in the Ogasawara Islands on May 30 at a depth of 664.0 km (412.6 mi).[2] The Associated Press agency reported "twelve people suffered minor injuries", and TEPCO claimed that 400 customers lost electricity in Saitama Prefecture.[3] There were no deaths, but elevators stopped one after another, in Tokyo and elsewhere.[4][5][6] The shaking of the earthquake was observed almost all over Japan.[7] It is believed that this was due to a deep-focus earthquake. This earthquake was one of the largest deep-focus earthquakes in the world.[8][9][10]
