Mt Ruapehu’s Crater Lake in New Zealand is experiencing a new heating phase, with the temperature rising to 29ยบC since mid-October. The lake’s color has shifted from blue-green to grey, indicating increased gas flow and sediment disturbance. Moderate sulphur dioxide emissions suggest partially open vents. Small earthquakes have been detected, but volcanic tremor levels are low. GNS Science states this activity aligns with typical hydrothermal system behavior during a heating episode, keeping the volcanic alert at Level 1.
