Thats funny minute after my post they updated it october SIXTH (oh will boys you nearly got it right). White Island latest VOLCANIC ALERT BULLETIN: WI – 2014/04 White Island Volcano Volcanic Alert Level 1 Aviation Colour Code: Green Monday 6 October 2014, 4 pm The lower levels of activity at White Island (Whakaari) have allowed for a more complete data set to be collected and confirm the volcano remains quiet. Now that volcanic unrest has decreased we have been able to continue aspects of our routine 3 monthly surveys. These include hot spring sampling, soil gas measurements and ground deformation surveys. Several hot springs are sampled to see if the geothermal system is changing. The recent results show no changes. The soil gas survey showed no marked changes since the last survey in 2012. While the ground deformation survey shows a few mm of uplift across the crater floor since June. No substantial changes in activity in the lake area or active vents were observed compared with previous visits. Volcanologist Brad Scott said: “It is great to be able to get a more complete set of data from the volcano and confirm the volcanic unrest remains at low levels. The last eruptions were in October 2013”. During their visits to the island in late September, GNS Science staff measured the lake temperature (53°C) and that o f fumarole F0 (149°C), on the southern part of ¬the crater floor. These are similar to other recent measurements. The lake level is still rising slowly rising. Since the lake re-established in late 2013 we have measured a rise of about 2.5 m. For the first time in almost 2 years we obtained a sample of the Crater Lake water and our anaylsis shows no significant changes, from the old lake. The fluids in the new lake are similar to those we observed in the old lake from 2003 to 2011. The Volcanic Alert Level remains at Level 1 (minor volcanic unrest). Typical volcanic unrest hazards remain and a range of activity can occur under these conditions with little or no useful warning. GNS Science is continuing to closely monitor the activity at White Island (and other New Zealand volcanoes) through the GeoNet project.
