Ruapehu volcano (North Island, New Zealand) activity update: new seismic unrest recorded
Wednesday Jan 15, 2020 09:30 AM | BY: MARTIN
Ruapehu volcano today (image: Geonet)GeoNet reported that the activity of volcanic tremor continues at low levels. Measurements of the volcano’s Crater Lake (Te Wai ā-moe) temperature, and chemistry remained consistent in combination with seismic unrest.
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.
