Small, muddy and geyser-like explosions are happening in the active crater at White Island this morning.
GNS Science posted an update saying the burst came as a result of the rising crater lake drowning active vents at Whakaari/White Island.
The geysering posed no risk to visitors and the Volcanic AlertLevel remained at Level 1.

Over the last three weeks, small-scale geyser-like explosions of mud and steam were observed in the active vent area, reaching a maximum height of about 10m.

These are not a sign of increasing volcanic activity.
The crater lake level had been rising since early-August which had impacted the surface activity around the active vents on the west side of the crater floor.
Geysering-type activity has become established in the main active vent due to hot steam and gas passing through the now drowned active vent area.
GNS Science and the National Geohazards Monitoring Centre continued to closely monitor Whakaari/White Island for further signs of activity.
