Ruapehu (North Island): (3 Aug) Since 22 July, volcanic tremor has gradually increased from weak to moderate levels, representing a minor change after nearly two years of consistently weak activity.

Interestingly, this seismic activity appears to have ceased since early July.
Crater Lake temperatures have remained stable over the past four months, fluctuating between 18 and 23°C due to daily weather variations and recent snowfall. Persistent upwelling, sulphur slicks on the lake surface, and a small but continuous overflow through the outlet channel continue to indicate ongoing hydrothermal activity.
