A pair of light earthquakes struck near the city of Auckland this afternoon.
Sunday, 17th March 2013
Two light earthquakes struck near Motutapu Island in the Hauraki Gulf this afternoon. Both quakes were shallow.
The first event struck just offshore on the eastern (Waiheke) side of Motutapu Island at 4:01 p.m. This magnitude 3.1 earthquake was 4 km deep.
At 4:06 p.m. a magnitude 3.9 quake struck beneath Motutapu Island at a depth of 6 km.
Aucklanders experience fewer earthquakes than inhabitants of some other parts of New Zealand, and most of those they feel are centred outside the region. The first of today’s local quakes was widely felt in Auckland city and suburbs. The larger second event was felt throughout the Auckland region and on the Coromandel Peninsula.
A swarm of half-a-dozen small earthquakes which occurred near Waiheke Island in November and December of 2005 attracted a lot of interest. A magnitude 2.5 earthquake was recorded near Waiheke Island on December 30th 2009.
GeoNet has issued a brief report on today’s earthquakes.
