Another earthquake swarm rattles Whakaari/White Island

A second swarm of earthquakes near Whakaari/White Island in as many months has re-triggered fears of a landslide.

GNS Science said there have been 95 quakes in the area since Thursday morning. The three largest measured 4.2, 4.0 and 3.7.

There are no changes in the level of volcanic activity, however.

"Our observations are consistent with minor volcanic unrest," GNS Science duty volcanologist Craig Miller said. "GNS Science continues to closely monitor Whakaari/White Island and our other active volcanoes."

The aviation colour code is also staying at green - meaning no eruption is believed imminent, and planes can fly freely in the area.

"The location of these earthquakes is the same as the May swarm," Miller said.

White Island is New Zealand's most active volcano, and according to GNS Science was "in a state of frequent eruption from 1976 to 2000". It's located 48km off the Bay of Plenty coast.
