Powerful earthquakes that rocked Taranaki this morning do not mean a bigger one is on the way a GNS scientist says.
Partying or not all Taranaki residents started 2013 with a bang when a 5.0 magnitude earthquake struck 30km off the coast of Opunake at 3.11am.
The big shake was followed two smaller aftershocks and then a powerful 4.3 magnitude quake at 3.42am.
GNS Science duty vulcanologist said Steve Sherburn said it was not unusual to have seismic activity in the Cape Egmont fault zone where they quakes have been located.
He said between 100 and 200 earthquakes were recorded in the area each year and today’s shakes did not imply more were too come.
”There was a magnitude 6.1 in 1974 offshore of Opunake so these things are not unusual. We don’t see any evidence of a build-up phenomenon. I would be very surprised if it didn’t just fade away,” he said.
