Regular gas flights and lake sampling are also undertaken as weather permits.
Since the last measurements lake temperatures have cycled around 22°C-28°C. For the last 10 years temperatures of the summit crater lake have cycled around 25°C.
Mt Ruapehu is still a very active volcano with the potential of little or no warning.
Both the Volcanic Alert Level (level 1) and Aviation Code (Green) remain unchanged.
