Friday, 24th May 2013

A magnitude 8.3 earthquake struck beneath the Sea of Okhotsk 360 km west-south-west of Esso, Russia (2375 km north-north-east of Tokyo , Japan) at 5:45 this evening, New Zealand time. The U.S. Geological Survey reports the quake was 600 km deep.

The Pacific Tsunami Warning Centre reported the quake as magnitude 8.2 at a depth of 620 km. The quake’s depth meant that a destructive tsunami was not generated.

Geoscience Australia reports the quake as magnitude 8.2 at a depth of 620 km. It estimates that the quake would have caused damage within 330 km of the epicentre, which includes part of the Kamchatka Peninsula, and would have been felt up to 4,000 km away.

Great quake triggers NZ seismograph network

The Japan Meteorological Agency which manages tsunami risk for Japan did not issue a bulletin for this event.
