At Ruapehu we monitor the lake temperature, water level and overflow along with the chemistry. The lake temperature varies from about 10 to 50Â°C; unfortunately this is not always a measure of activity as eruptions have occurred from both hot and cold lakes. The Mg (magnesium) values increase if new/fresh rock is in contact with the crater lake waters, while the Cl (chloride) changes with steam input.
