Cape Egmont Swarm June 2010

Over the week of 4th – 11th June 2010 a series of 9 earthquakes occurred west of Mt. Taranaki in the area known as the Cape Egmont Fault Zone.
The initial quake appears to be a double quake with the same time reading, but 2.13km apart. The 3.572ML event was reported MM4 (largely observed) at Pungarehu [1], Rahotu [1] and Warea [1].

A moderate 5.318ML earthquake occurred on Saturday, June 12 2010 at 2:20 am NZST 100km to the south and was reported widely felt throughout the lower North Island and upper South Island. It is unclear if this larger event is related to the Cape Egmont swarm as the faults south of the Cape Egmont Fault Zone in the South Taranaki Bight have yet to be determined west of the Manaia Fault.
