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

06:00 AM | BY: VN

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.
The Volcanic Alert Level remained at 2 (moderate to heightened unrest) and the Aviation Colour Code remained at Yellow.

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
