White Island volcano (New Zealand): new eruption, ash emissions from Crater lake

A new eruption has started from White Island volcano early today. An ash plume is rising to 4-6000 ft (1.3-1.8 km) altitude. The eruption consists of ash venting from a new cone that is beeing built in the Crater Lake, and followed a sharp DECREASE in tremor.

GeoNet rissued the following report:
"

Around 11:30 pm on August 7 volcanic tremor at White Island sharply decreased to levels seen prior to the current episode of unrest in late July. A few hours after this drop in tremor, the colour of the plume changed from white to light brown, indicating more ash is now in the plume.
Visual observations in recent days show that a small cone is being built in the lake, around the main area of degassing.

This is the first time ash has been produced from White Island since 2000 and may represent the start of a new phase of activity at White Island.

Visitors to White Island are now at the highest level of risk since the end of the 2000 eruptions. Additional hazards to visitors to the island now include the health effects of ash and acid gas exposure, including respiratory issues, skin and eye sensitivity to acid gases. These hazards increase significantly towards the Crater Lake rim. Eruptions can occur at any time with little or no warning. We advise a high level of caution should be taken, if visiting the island.

The ashfall prediction plot for 6:00 pm today indicates where volcanic ash may be deposited if ash continues to be produced from the volcano.

GNS volcanologists plan to visit the island this week to assess the situation and undertake further sampling and measurements.

White Island volcano has erupted like its web cam captured. Visitors are warned that further and stronger eruptions are possible. The (hydrothermal?) eruptions occour without warning and also the alert level has changed to 2 because of the experiencing signs of elevated unrest above known background levels. There was no ash eruption yet. The alert level has also changed from one to two due to "minor eruptive activity". It follows a code change last week when scientists discovered water levels in Crater Lake rose by about 3m to 5m overnight and the number of tremors had increased. There was a particularly stronger seismic episode recorded Sunday morning, ending in a volcanic earthquake at 4.54am that day. "It's told that it is now at similar levels to before the weekend." ...
