Mike Ross mentioned that hydrothermal activity on White Island is above normal scales.

The volcano had shown some unrest last year, by chance (?) on the same day as Tongariro. Check …Eruptions at Tongariro & Whaakari (White Island) and 1 million viewers! Author Carl August 7th. Bruce Stout agreed that this year it might be a volcano to keep an close eye on. So i thought I’d write a short summary stating some facts and preparing a link collection, so that if something should happen, we have this already in store.
The RSAM &SSAm plot of the last month also shows increased activity.
This might be due to weather, but if you watch the hydrothermal action on the video Mike pointed out, volcanic unrest could be the cause as well. At the moment White Island is shown as color code yellow.
Portrait and history:
White Island, or as the Maori called it, Whakaari is a volcano located on an island not quite 50 km of the west coast of the North Island of New Zealand in the Bay of Plenty. It is very closely monitored by GeoNet the New Zealand observatory of earthquakes and volcanoes: http://www.geonet.org.nz/volcano/info/whiteisland
White island is an andesit stratovolcano. Although it is said to have been active for the last 150000 years it is only 321 meters above sea level and only around 2km wide, but one needs to bear in mind that it rises 1600 meters above the sea floor and this makes it the largest active volcanic structure in New Zealand. It is part of the Taupo Volcanic Zone on which Bruce Stout wrote a great series.

It has produced lava flows as well as an ash eruptions in the past. The Maori name “Te Puia o Whakaari” means “The Dramatic Volcano”. The name we use here now, originates from Captain Cook who saw it on October 1, 1769 covered in a white cloud when he sailed by. Attempts were made to use the island for mining sulfur but this came to an aprupt halt when a crater rim collapsed producing a lahar which killed all the workers ( but not the camp cat) in 1914.
Tourists can book a tour for example on http://www.whiteisland.co.nz/ or http://www.wi.co.nz/ or http://www.whakatane.com/attractions-activities/white-island. I wouldn’t recommend it at the very moment though.
Someone glued a Flintstones Dino figurine to some piece of wood in front of the White Island crater cam in May 2004. It was not expected to last long so it was left to stay and was still there last time I checked ( today).
Erik Klemetti wrote about a strange kind of spine evolving from the crater on the 12.11.12. http://www.wired.com/wiredscience/2012/12/the-strange-spine-of-new-zealands-white-island-volcano/

Apparently White Island is cyclical between strombolian eruptions and large-scale lava extrusions. http://petrology.oxfordjournals.org/content/41/6/867.full
