Mt Ruapehu crater lake heats up to 43C, Alert level raised to 2 – TangataWhenua com

3 months ago Crater Lake (Te Wai ā-moe) continues heating and is now 43 °C. The heating has been accompanied by bursts of volcanic tremor and a marked increase in the amount of gas passing through the crater lake. The volcanic alert level has been raised to Level 2 and the Aviation Colour code changed to Yellow (Source: GeoNat). The Crater Lake (Te Wai ā-moe) temperature has been rising and is now 43ºC. During a gas flight last week, the lake was observed to be a uniform grey colour which shows it is well-mixed. There is some flow over the outlet. The gas output through the crater lake has also increased markedly in response to this heating cycle. The amounts of carbon dioxide (CO2) and sulphur gases (SO2 and H2S) in the plume are the largest measured in the past two decades. The continued flow of gases and hydrothermal fluids though the lake shows that the underlying vent area is open.

Wellington scoop co nz » Volcanic alert level on Mt Ruapehu has been raised – crater lake is heating

Photo from RNZ News from GeoNet The temperature of the crater lake (Te Wai ā-moe) at Mt Ruapehu has decreased from 43 to 41 °C during the past week. The level of volcanic tremor continues to be moderate to strong and a small number of shallow volcanic earthquakes have been recorded. While the crater lake may have stopped heating, volcanic activity at Mt Ruapehu remains elevated. The Volcanic Alert Level remains at Level 2 and the Aviation Colour Code remains at Yellow. Since our last update, Ruapehu’s Crater Lake (Te Wai ā-moe) temperature has decreased slightly. The temperature reached a maximum of 43 ºC on Monday 21st December that subsequently declined to ~41 ºC. A lake temperature peak of ~ 40-46 ºC is common during these heating-cooling cycles; on at least 7 occasions since 2007, the lake temperature exceeded 40 ºC. Using this lake temperature decrease, we estimate that the energy input into the lake has decreased from ~400 to ~200 MW (megawatt).

Mt Ruapehu: What volcanic unrest and the increased alert level means

An eruption may include explosions, flying rocks, fast-moving hot ash clouds, lava flows and domes, landslides, volcanic gases, lightning and or earthquakes. “The Volcanic Alert Level reflects the current level of volcanic unrest or activity and is not a forecast of future activity,” a statement from Michael Rosenberg, duty volcanologist at GeoNet, read. GNS Science/Supplied A GNS Science technician takes measurements at Mt Ruapehu s Crater Lake as part of regular monitoring of the volcano (FILE). How often does the lake heat up? The Crater Lake has heated up like this many times before without resulting in an eruption, and it often fluctuates between 15C and 45C throughout the year.
