Ruapehu volcano (New Zealand): crater lake temperature increased

GNS reported that "the temperature of Crater Lake has started to rise and has now reached 30°C. It has been accompanied by some minor volcanic tremor. The chemistry data from our last sampling trip confirms the decline of temperature in the deep geothermal system.
Volcanologist Brad Scott said these data indicate the Crater Lake is returning to a more typical state, where heat and gas flow from depth is entering the lake. The anomaly of higher heat at depth and cooler temperatures in the lake appears to have passed. However the volcano remains in unrest and eruptions could still occur with no warning."
