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...
June 06, 2018
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...
March 21, 2018
An increase in volcanic gas emissions and sustained high lake temperature (Te Wai Ā-Moe) suggest a slightly higher level of activity at New Zealand's Mount Ruapehu, GeoNet reports. The Volcanic Alert Level remains at 1 and the Aviation Color Code at Green. The...
November 25, 2017
New Zealand's Mount Ruapehu remains in a state of heightened volcanic unrest. The temperature of the summit Crater Lake has declined from 46 °C (114.8 °F), but the cooling has stopped and the temperature is rising again. Recent visits to the volcano have...
June 08, 2016
GNS scientists have observed an increase in the output of volcanic gas from Mount Ruapehu's Crater Lake on May 10, 2016. As a result, the Volcanic Alert Level was raised to Level 2. The Aviation Colour Code was also changed, from Green to Yellow. New...
May 11, 2016
A volcanic earthquake swarm is being recorded beneath the Crater Lake of Mount Ruapehu since April 26, 2016, GeoNet reports. Swarms of volcanic earthquakes like these are uncommon on Ruapehu in recent years. The most recent eruption of this volcano occurred on...
