White Island volcano (New Zealand) activity update: elevated seismic unrest continues

GeoNet did a gas flight that confirms the steady decline in both CO2 and SO2 flux since the eruption, albeit at slightly elevated levels. The result from this flight is consistent with recent gas measurements and indicates the continued presence of shallow magma beneath the primary vent area.

Temperatures exceeding 660 °C mean that the system remains very hot with no sign of cooling over the past two weeks. Despite these high fumarole temperatures, a small pond of water is present in the primary vent area and small-scale jetting is now occurring. This is similar to the activity seen in September-December 2019.
Although very unlikely, the active vent area remains potentially unstable and an eruption could occur with limited precursory activity. The GeoNet team consider an eruption to be very unlikely (1 %) in any 24-hour period.
Satellite data retrieved over the last two weeks shows continued land movement, at a reduced rate along the west wall of the Main Crater and the 1914 landslide scarp. No obvious changes were noted along the landslide scarps on the latest observation flight (12 February).
Volcanic Alert Level remains at Level 2.

Tuesday, Feb 04, 2020
GeoNet did a visual observation and gas flights last week and confirm no further extrusions of lava has occurred. Gas fluxes are lower than two weeks ago but remain elevated. ... [more]

GeoNet recorded strong and hot emissions of gases and steam plumes that occured and continue since 9 December, causing a glow that is seen on infrared cameras. Occasional minor ash emissions can be emitted from the active vent due to erosion. ... [more]
Saturday, Dec 28, 2019
GeoNet reported that during 18-23 December the level of volcanic tremor at the volcano remained low and gas-and-steam plumes were strongly emitted from the new vent area. ... [more]

No new eruption occurred during the recent phase of intense tremor, which has again declined. However, this could change quickly again and the official Volcanic Alert Level remains at Level 2. [more]
Thursday, Dec 12, 2019
The activity at the volcano remains elevated, with high levels of volcanic tremor indicating internal fluid movements and instability. However, no further eruptions have occurred since the fatal one on Monday 9 Dec. ... [more]
