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]

On the 21 November 2012 an eruption 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 rich plume.[3][F 1] The eruption was measured by GNS who produced a Tongariro eruption time series.
The SO2 anomaly flagCite error: Invalid <ref> tag; refs with no name must have content for [IASI] overpass at X.X on the X 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.
Footnotes [F]
- ↑ The Herald article gives the time of eruption as "just before 1.30pm" failing to observe that that GNS reports time in NZST.
