What future activity could look like at Ruapehu volcano, New Zealand
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.
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.
Steam plume visible at Ruapehu volcano, New Zealand
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.
High levels of volcanic gas emissions, strong volcanic tremor at Ruapehu, New Zealand
Recent airborne gas measurements over Ruapehu volcano, New Zealand confirm continued high levels of volcanic gas emissions, along with strong volcanic tremor.
Tremor at Ruapehu volcano now longest and strongest in 20 years, New Zealand
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.
Strong volcanic tremor continues at Ruapehu, New Zealand
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.
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.
Sequence of tectonic earthquakes under the summit of Ruapehu volcano, New Zealand
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….
Heightened volcanic unrest at Mount Ruapehu, New Zealand
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…
Increased volcanic unrest at Mount Ruapehu, Alert Level and Aviation Color Code raised, New Zealand
The Volcanic Alert Level for Mount Ruapehu has been raised to 2 and the Aviation Color Code to Yellow on December 21, 2020, following an increase in Crater Lake temperature and the largest measured gas output in the past two decades. The Volcanic Alert Level…
