The 2015 Ogasawara earthquake was a 7.8 magnitude earthquake which struck offshore 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). The shaking of the earthquake was observed almost all over Japan, as it was one of the largest deep-focus earthquakes recorded worldwide.

Damage and casualties

The Associated Press agency reported "twelve people suffered minor injuries", and TEPCO stated that 400 customers lost electricity in Saitama Prefecture. There were no deaths, but elevators stopped working in Tokyo and elsewhere.
