Heightened volcanic unrest continues at Ruapehu with high volcanic gas output, strong tremor and steam plumes

High levels of volcanic gas emissions and strong volcanic tremor continue at New Zealand’s Ruapehu volcano. The Crater Lake (Te Wai ā-moe) temperature has risen to 41 °C (105.8 °F) and steam plumes can be observed in cold, still atmospheric conditions. The volcano is still at a heightened level of unrest. The Volcanic Alert Level remains at 2, with greater chances of eruption over the next four weeks than at Volcanic Alert Level 1.

Elevated volcanic unrest at Mt. Ruapehu, CO2 output now 2nd highest ever recorded, New Zealand

Elevated volcanic unrest at Mt. Ruapehu, CO2 output now 2nd highest ever recorded, New Zealand

ls of volcanic unrest continue at New Zealand’s Ruapehu volcano. This is primarily manifested as strong volcanic tremor, slowly rising Crater Lake (Te Wai ā-moe) temperatures and high gas outputs. These changes indicate magma may now be driving the unrest, increasing the chances of further activity. The Volcanic Alert Level remains at Level 2.
