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.
