Weak Ash Plume Observed at Whakaari as Alert Level Remains Unchanged

Whakaari/White Island has emitted intermittent weak ash plumes, but the volcanic alert level remains at level 2 and the aviation colour code at yellow.

Earth Sciences New Zealand (ESNZ) said webcams first detected a weak ash plume at 10.06am on Friday, October 16, with the activity continuing intermittently throughout the day.

The latest activity follows a week of vigorous steam and gas emissions from the volcano.

ESNZ said the ash was visible on webcam images but not detected by satellite imagery, suggesting only a small amount was being emitted.

Scientists believe the ash is likely being carried into the steam plume as vigorous steam and gas emissions erode the volcanic vent walls, rather than being produced by an explosive eruption.

A similar process was observed in March 2026, and scientists say the activity could occur intermittently over the coming days.

A small amount of ash has been falling from the plume around Whakaari, with any ashfall expected to be confined to within a few kilometres of the island.

Ashfall affecting the mainland is considered unlikely, according to ESNZ.

With no evidence of explosive activity, scientists have maintained the Volcanic Alert Level at 2 and the Aviation Colour Code at Yellow.

However, the agency warns volcanic activity could escalate with little or no warning, with sudden, more explosive events potentially affecting the crater floor and the immediate vicinity of the island.

Earth Sciences New Zealand and the National Geohazards Monitoring Centre will continue to closely monitor Whakaari/White Island for changes in volcanic activity.

Further updates will be provided if new information becomes available or the volcano’s status changes.
