Sunday 26th April 2009

A magnitude 6.1 earthquake struck 125 km north-north-east of L’Esperance Rock just after midday today. The 12:07 p.m. quake was 142 km deep according to the U.S. Geological Survey which reports that the epicentre was 135 km south-south-west of Raoul Island (960 km north-east of Auckland.)

Geoscience Australia also reports the quake at magnitude 6.1 but at the shallower depth of 113 km. A calculation suggests the quake would have been felt up to 500 km from the epicentre.

On Friday evening a shallow magnitude 5.2 event was reported 120 km east-south-east of L’Esperance Rock.

A sixth magnitude quake was reported 60 km north-east of Raoul Island on the afternoon of Saturday the 18th. Estimates of the earthquake’s strength range between magnitude 5.9 and 6.2.

Earthquakes of magnitude 4.8 and 5.2 were reported near Raoul Island and an event of magnitude 5.4 near L’Esperance Rock earlier in the month.
