Whakaari White Island Alert Level Raised

Following weak volcanic plume this morning, Whakaari/White Island's volcanic alert level has raised to three and aviation colour code changed to orange.

Earth Sciences New Zealand Geologist Michael Rosenberg said "This morning, photos from near Whakaari/White Island show some ash being expelled in the low-level plume."

This morning a pilot reported ash is being emitted in weak eruption from the main vent area, Rosenberg said. 

"The images shared with us show ashfall on the main crater floor but no obvious changes to the vent or any eruption of rocks."

Due to this, the alert level has been raised. 

Since last week, steam and gas plume has been visible from the coast. 

"Small amounts of volcanic sulphur dioxide gas are being detected by the TropOMI satellite sensor," indicating a slight increase in activity Rosenberg said. 

He warned at the current wind direction and strength, "minute traces of ash could reach the Bay of 
Plenty coast but is ashfall is unlikely to be noticeable at ground level." 

The intensity of volcanic activity could increase with little to no warning, but would mostly impact "the crater floor area and immediate 
vicinity of the island." 

Scientists will make a gas-measuring and observation flight as soon as weather conditions allow.

Lack of real time monitoring and satellite imagery means the alert level will remain at level three and aviation colour code orange until observations are made in the coming days.
