White Island has remained quiet overnight following yesterday's eruption, GeoNet says.

Duty volcanologist Nico Fournier said the activity remained at a low level, similar to that following yesterday's eruption.

There was still potential for further eruptions that may occur without warning, he said.

The small eruption at 10.23am yesterday lasted for about 10 minutes, and produced a 4km-high plume of steam visible from Bay of Plenty.

The island's volcanic alert level remains at 2, which indicates minor eruptive activity, and the aviation colour code is orange, down from red yesterday.
