Monday, 25th February 2013

Two undersea earthquakes have struck off East Cape since midnight.

The first event was a magnitude 4.2 earthquake which struck 195 north-east of Te Araroa at 3:41. This quake was 7 km deep. No felt reports have been lodged with GeoNet.

At 9:55 a magnitude 5.3 earthquake struck 785 km north-east of Gisborne at a depth of 1 km. GeoNet’s earthquake analysis application initially reported this as a magnitude 4.7 quake centred 265 km north-east of Te Araroa with a depth of 0 km. This quake was not felt on-shore in New Zealand and the magnitude and location were revised by a seismologist.

The U.S. Geological Survey reports this second event as magnitude 5.4 centred of 114 km south-east of L’Esperance Rock in the Kermadecs, 802 km north-north-east of Gisborne, at a depth of 10 km.

A magnitude 6.1 quake struck near L’Esperance Rock on February 19th and a magnitude 6.3 quake struck north-east of Te Araroa on the 16th.
