White Island activity 'steady'
White Island volcano has remained at a persistent low level of activity, including volcanic tremor and
No small mud or ash eruptions have been observed since earliest April. The lower level of activity has prompted GeoNet to reduce the Aviation Colour Code to Green (indicating no active eruption activity) from Yellow (indicating heightened unrest and eruptive activity). The Volcano Alert Level remains at 1.
Seismic tremor has continued within a range of low to moderate amplitude levels, while gas measurements continue to show a consistent magma degassing signature.

Brad Scott, who visited the volcano last week, confirms “the rainfall over the past few weeks has caused a lake level increase and the two lakes have joined, creating one larger lake. Temperature of the lake is variable, with a maximum of about 62°C being measured. In contrast the nearby lava dome which was extruded in November has temperatures of about 200°C”.
As part of GeoNet's programme to improve monitoring at White Island the web camera on the crater rim has been upgraded. This provides clearer pictures and better low light (night) views. Camera images can be seen herehttp://www.geonet.org.nz/volcano/info/whiteisland.
