A brief period of strong volcanic tremor was recorded over the weekend at Ruapehu volcano, New Zealand. The Volcanic Alert Level remains at Level 2. An eruption at the volcano may occur at any level, and levels may not move in sequence as activity can change rapidly.
GNS Science Senior Volcanologist Geoff Kilgour provides a video update on the volcanic unrest at Ruapehu. He shares what future activity could look like at the volcano.
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.
A steam plume was seen above Ruapehu’s Crater Lake at around 09:45 LT on May 3, 2022 (21:45 UTC on May 2). No seismic or acoustic activity accompanied the plume appearance, indicating the steam plume was not generated by strong activity in the lake.
Recent airborne gas measurements over Ruapehu volcano, New Zealand confirm continued high levels of volcanic gas emissions, along with strong volcanic tremor.
Elevated volcanic unrest continues at New Zealand’s Ruapehu volcano, dominated by strong volcanic tremor. The Crater Lake (Te Wai ā-moe) temperature remains stable at 37 °C (98.6 °F) and the Volcanic Alert Level remains at Level 2.
The elevated volcanic unrest continues at New Zealand’s Ruapehu volcano, with strong volcanic tremor and the Crater Lake (Te Wai ā-moe) temperature now stabilized at 37 °C (98.6 °F) for the past week. The Volcanic Alert Level remains at Level 2 and the Aviation Color Code at Yellow.
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.
Tectonic earthquakes are being registered beneath the summit area of Ruapehu volcano in New Zealand since December 30, 2021. While these earthquakes are uncommon, none of the monitoring data suggests that the volcano is exhibiting increased levels of activity….
The temperature of the Crater Lake (Te Wai ā-moe) at Ruapehu volcano has decreased from 43 to 41 °C (109 – 106 °F) during the past week. The level of volcanic tremor continues to be moderate to strong and a small number of shallow volcanic earthquakes have…
