A minor eruption has occurred at Whakaari/White Island.
The Volcanic Alert Level has now been raised to Level 3 and the Aviation Colour Code raised to orange.
On Geonet's website, duty volcanologist Geoff Kilgour said the volcano had produced "a more vigorous plume" on Friday afternoon, moving volanic ash to the east of the island.
"There is a low probability of this ash affecting the mainland. This weak eruptive activity was identified through a combination of webcam imagery and satellite data provided by our colleagues from the Volcanic Ash Advisory Centre at NZ MetService.
"The activity appears to have been most active from around 1 to 3 pm and has since diminished. Satellite data shows that the plume appears to have contained a minor amount of volcanic ash."
Kilgour said the volcano was currently experiencing a period "of elevated unrest".
Steam and ash emissions "could continue for some time".
Kilgour said it was very unlikely that volanic ash will affect the mainland.
He said GNS Science will be monitoring the island over the weekend.
