Ruapehu volcano (New Zealand): crater lake at lowest temperature since 2010

Recent measurements by NZ scientists indicate that the volcano's crater lake is currently in a cooling trend. At 15 deg C, it has the lowest temperature recorded since April 2010.
According to GeoNet, the current cycle is part of the normal behavior of the lake.
It does not exclude the possibility of a sudden eruption, although makes it less likely. Heat flow and chemistry indicate the vents are not sealed from the lake.

"Most eruptions from Crater Lake occur when it is hot, however some have also occurred from a cool lake. To put this in context, since 1965 there have been 35 eruptions through Crater Lake that have affected the wider summit area of Mt Ruapehu, only three of those came from cooler lakes (December 1979, December 1988 and September 2007). Hence it is very unlikely (9%) that an eruption of Mt Ruapehu affecting the wider summit area will occur while the lake temperature is less than 22°C."
