A swarm of earthquakes has rocked White Island, with 196 of various magnitudes recorded since Thursday.
White Island, or Whakaari, lies 50km offshore from Whakatāne and is an active marine volcano.
GeoNet duty volcanologist Natalia Deligne confirmed that a swarm of quakes started on Thursday and over the last24 hours the rate and magnitude had increased.
Deligne said the swarm does not appear to be linked to volcanic unrest but may result in increased landslide risk on the island.
"Since Thursday, 196 earthquakes have been located, 22 earthquakes of magnitude 3 or greater have occurred in the last 24 hours, and the largest three are M3.9, M3.8, and M3.8," she said.
"The swarm appears to be tectonic in nature, unrelated to volcanic processes."
Deligne said there may be a heightened risk of landslides as the earthquakes were shallow and local and the island's material was relatively weak.
"There are no changes in volcano monitoring parameters or the level of volcanic activity at Whakaari/White Island," she said.
