Tongariro is a compound volcano in the Taupo Volcanic Zone of the North Island of New Zealand.
Eruptions
6 August 2012 23:52 NZST (6 August 2012 10:52 GMT)
After a couple of weeks of increased earthquake activity and changes in gas emission, Mount Tongariro had a phreatic (gas and steam driven) eruption on Monday 6 August 2012 at 11.52 pm NZST. The eruption lasted only a couple of minutes and occurred partly from existing vents at the Upper Te Maari Crater.[1]
21 November 2012 13:24:50 NZDT (21 November 2012 00:24:50 GMT)
At 1:24 pm NZDT on the 21 November 2012 an eruption of the Upper Te Maari crater ejected ash to a height of 3-4 km. the eruption lasted approx 5 min.[2] A nearby walking party took a video of the eruption showing the rapid ascent of the ash plume.[3] The eruption was measured by GNS who produced a Tongariro eruption time series.
The SO2 anomaly flag [4] for IASI overpass at 9am (UTC) on the 22 November shows four anomalous pixels surrounding the location of Mt Tongariro. The SO2 had passed below the dectable limit by the time of the next overpass at Y.Y.
