Ruapehu volcano (New Zealand): alert level raised due to increased degassing and heat output

Fri, 13 May 2016, 17:38 17:38 PM | BY: T
The alert level of the volcano was raised by a notch from 1 to Level 2 (moderate to heightened unrest) last Wednesday, Geonet informed in a special note.
This was triggered by recent measurements that showed an increase in the degassing from Mt Ruapehu's Crater Lake, a rise in temperature from 25 to 45 deg C since mid April, and ongoing moderate levels of volcanic tremor (reflecting the degassing).
The Aviation Color Code was also raised from Green to Yellow.
Whether or not the volcano is going to produce a new eruption in the near or medium future is still far from certain. According to the Geonet, the volcano's current seismicity and increased heat flow are "not exceptional in terms of the last few years." The current unrest could (but not necessarily must) be a precursor of new volcanic activity at Ruapehu in the medium-term future (weeks to months), but it could as well remain a peak in temporary elevated internal activity only, such as the volcano's many regular heating cycles which typically do not escalate into eruptions.

Ruapehu volcano (North Island, New Zealand) - Smithsonian / USGS Weekly Volcanic Activity Report for 11 May-17 May 2016 (New Activity / Unrest)

On 17 May GeoNet reported that the lake temperature of Ruapehu's summit Crater Lake had decreased from a high of 46 degrees Celsius to 39 degrees, with some of the decrease attributed to rain and snowfall. Moderate levels of volcanic tremor continued, and analysis of water samples collected the previous week showed no changes in the lake chemistry. During recent visits, scientists measured a larger output of volcanic gases. ... Read all

Ruapehu volcano (North Island, New Zealand) - Smithsonian / USGS Weekly Volcanic Activity Report for 4 May-10 May 2016 (New Activity / Unrest)

GeoNet reported that a volcanic earthquake swarm beneath Ruapehu's summit Crater Lake was detected during 25-26 April. This type of swarm has been uncommon at the volcano in recent years, when volcanic tremor has dominated the seismicity. In addition, the crater lake water temperature had been rising since late 2015, from 25 degrees Celsius to 40 degrees in the last half of April. ... Read all
