White Island volcano (New Zealand) activity update
Friday Jul 26, 2013 12:05 PM | DOOR: T
GNS Science says that minor activity has become re-established at White Island over the last 24 hours. The Volcano Alert Level remains at Level 1 and Aviation Colour Code has been raised to Yellow.
Following an increase in volcanic tremor levels overnight and images of activity on the volcano cameras, a response visit was made this afternoon. Volcanologist Brad Scott reported they saw two styles of activity in the active vent. Audible jets of gas were being shot through the small lake and broader expanding ‘bubbles’ of dark lake sediments and debris were being ejected 20-30 m vertically. The activity is very similar to earlier this year.
The potential for larger, more explosive eruptions that might impact on visitors to the island is always present. Any larger eruptions may occur with no warning to any visitors to the island.
The ultimate outcome of the current activity at White Island remains unclear and GNS Science continues to closely monitor White Island through the GeoNet project. There is no reason to believe this change is related to the Cook Strait earthquakes.
Unrest at White Island began in July 2012, leading to explosive eruptions and ash emissions in August. A small lava extrusion occurred in November, followed by phreatic, steam driven activity in December which continued through January and February 2013. Very minor ash emissions have been interspersed throughout this eruption sequence as conditions within the craters have changed.
The Volcanic Alert Level ranges from 0 to 5 and defines the current status at a volcano. Level 1 indicates signs of volcanic unrest.

The "drumbeat" earthquake activity, which could be caused by pulsating steam and gas emissions from a narrow conduit continues. Over the past days, the intensity of seismic activity has risen, but dropped again a bit at the moment. [meer...]

Geonet has lowered the alert level of the volcano back to green (normal), following a gradual decline in seismic activity over the past weeks. Degassing remains intense, and after heavy rainfall during the recent past, a lake has been re-established at the main crater. [meer...]
