Whakaari/White Island has had its alert level increased to three after a minor volcanic eruption this morning.
GNS Science volcanologist Yannik Behr said a “vigorous” steam plume was observed above the island at around 8.20am on Friday.
“As we have no sensors on the island we are relying on webcams and satellite imagery to assess the situation.”
Limited information meant there was no clear indication if there was ash in the plume, he said.
“If there was, it would be unlikely to reach the mainland under current wind conditions.”
The Aviation Colour Code was raised to Orange, meaning a volcanic eruption was underway with no or minor ash emission.
Behr said the steam plume above the island has reverted to more normal levels.
“GNS Science volcanologists are monitoring the volcano and further information will be released as soon as it is available.
“As that information becomes available, we may change the Volcanic Alert Level to more accurately reflect the current situation.”
An eruption of the volcano in 2019 killed 22 people and injured 25 others.
