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…
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…
Mount Ruapehu's Crater Lake (Te Wai a-Moe) heated from 24 °C (75.2 °F) to 40 °C (104 °F) in response to earthquakes beneath the volcano, according to the GeoNet bulletin issued on Wednesday, March 18, 2020. The Volcanic Alert Level remains at…
Crater Lake (Te Wai ā-moe) has responded to a short-lived episode of volcanic earthquakes beneath Mount Ruapehu, detected on February 22 and 23, 2020. Seismicity declined after initial uptick but is now back at similar levels. To further understand the current…
A short-lived episode of volcanic earthquakes occurred beneath Mt. Ruapehu on February 22 and 23, 2020. The sequence now appears to be over. The Volcanic Alert Level, therefore, remains at Level 1. The last known eruption of this volcano took place in 2007 (VEI…
GNS Science volcanologists are reporting another phase of high lake temperatures at Te Wai ā-moe (Crater Lake), Mount Ruapehu along with moderate levels of volcanic tremor. The Volcanic Alert Level remains at 1. GeoNet is continuously recording the temperature of…
The temperature at Te Wai ā-moe (Crater Lake) at New Zealand's Mount Ruapehu is rising along with an increase in volcanic tremor, GNS Science reported June 6, 2018. While this is consistent with minor volcanic unrest behavior, it is a useful reminder that…
An episode of volcanic earthquakes is occurring beneath Mount Ruapehu since March 15, 2018. This is a common observation during a heating phase of the crater lake (Te Wai ā-moe), GeoNet scientist Brad Scott reports. Crater lake's current temperature of 39…
