Ruapehu volcano today (image: GeoNet)
GeoNet observatory reported that since April 2020, lake temperature has decreased from a high of 42°C to around 22-23 °C. This lower lake temperature is normal for Crater Lake. To keep the lake at this temperature, low-level heat must continue to flow into the lake. This indicates that the underlying vent area is open to volcanic gases and hydrothermal fluids. Other signs that point to this open vent are visible upwellings and sulphur slicks on the lake surface. ...more read all

GeoNet reported that the activity at Crater Lake (Te Wai ā-moe) is often dominated by a heating-cooling cycle. These cycles last weeks-to-months. After peaking in April at 42°C, the lake cooled to 35°C by early May. Recent monitoring indicates continuous gas flux which has kept the temperature around 35°C through May. ...more read all

Crater Lake at Ruapehu volcano (image: @geonet/twitter)
GeoNet reported that during February-April, Crater Lake (Te Wai ā-moe) heated slowly to a peak temperature of 42ºC. Due to a heating-cooling cycle, there is a period of slow change before a cooling trend is clearly shown in the data. That trend is now confirmed with current temperatures close to 35ºC, with further slow cooling expected. Colour temperature is grey with a few surface slicks and no obvious upwelling. At that time the water level had dropped to about 30 cm below overflow but following this weekend’s rain the lake is again overflowing into the upper Whangaehu River. ...more read all

GNS Science Volcanologists have collected water samples from Crater Lake (Te Wai ā-moe) and the temperature of the lake is now 40°C. GeoNet believe the heating of the lake is the response to an input of hot gases and hydrothermal fluids in the wake of volcanic earthquakes beneath Mt Ruapehu in February. Prior to the earthquakes, the lake measured 24ºC. ...more read all

GeoNet volcanologists have collected water samples from Crater Lake and measured volcanic gases in the plume last week. Seismic data have been analysed in detail. ...more read all

Ruapehu volcano today (image: Geonet)
GeoNet reported that seismographs detected a sequence of seismic events beneath Mt Ruapehu during 22-23 February. GNS Science volcanologists have categorised them as volcanic earthquakes. The larger events at the start of the episode are approximately magnitude 1.5 and later, smaller events are too small to be located by GeoNet’s earthquake detection-location system. ...more read all

Ruapehu volcano today (image: Geonet)
GeoNet reported that the activity of volcanic tremor continues at low levels. Measurements of the volcano’s Crater Lake (Te Wai ā-moe) temperature, and chemistry remained consistent in combination with seismic unrest. ...more read all
