A magnitude 6.1 earthquake struck 103 km north-east of L’Esperance Rock in the Kermadec Islands at 9:17 this morning. The undersea quake was centred 169 km south of Raoul Island (942 km north-east of Auckland) at a depth of 20 km according to the U.S. Geological Survey.
Geoscience Australia reports the quake as magnitude 6.0 at a depth of 21 km. It estimates that the quake would have caused damage within 40 km of the epicentre and would have been felt up to 450 km away.
The Pacific Tsunami Warning Centre did not issue a bulletin for this event.
