Gas-measuring and observation flights on 16 November reported small amounts of ash in the plume. Overall, observations indicate a lower level of ash emission over the past few days.
The amounts of CO2 (carbon dioxide) and SO2 (sulfur dioxide) volcanic gases carried in the plume continue to be elevated above background levels but are now slightly lower than last week’s measurements. Sulfur dioxide (SO2) and carbon dioxide (CO2) emissions reached to a 710 tonnes/day and 1937 tonnes/day, respectively.
Laboratory analyses of the ash shows it comprises hydrothermal minerals and old volcanic material and that no new magma is present. The ash particles are material eroded from the 2019 vent area by the flow of steam and gas.
During the past week, a sequence of small earthquakes and a larger than normal volcanic earthquake were located close to the volcano. Low-level volcanic tremor continues.
The Volcanic Alert Level remains at Level 2.

GeoNet reported that an observations during the gas flight confirmed the presence of fine ash material in the plume. The fine particles originate from the main steam vent at the back of the crater lake. Initial analyses of the ash particles suggest that it is loose material from around the vent or underlying conduit being carried by the steam and gas emission. ... read all
