Read the latest pānui from GNS Science about current volcanic monitoring on Ruapehu

GNS Science are reporting that the Crater Lake is currently in a heating phase which started in late 2014 when the lake was 15°C, reaching a peak of over 40°C in late January - early February 2015.

The temperature declined to about 31°C in mid March and is now at 37-39°C. They have not observed any other changes at the Crater Lake.

Over the last 2-3 weeks they have been recording intermittent moderate to strong levels of volcanic tremor at Mt Ruapehu, which has been some of the strongest they have seen in the last 8 years.

The signals are similar to those in 2006 and 2007 but weaker than those recorded in 1994/1995.
