GeoNet volcanologists did a flight observations and aerial-based measurements of the volcano. Results from the most recent gas flight on 27 May indicate an increased gas flux since the previous flight on 20 May. While previous observations indicated a trend back to levels that are typical for this volcano, the recent increase in SO2 and CO2 gas flux, could be attributed to a new batch of the magma beneath the volcano at shallow depth. Thermal infrared images, taken during the observation flight on 20 May, show that the lava extrusions, first detected in early January, are still very hot, at around 500 °C. Hot gases that are being emitted around these lava lobes generate a glow that can be seen on webcam images. ... [подробнее]

The volcano continues to emit SO2 gas, which is derived from magma at shallow depth beneath the surface and is one of the main indicators of volcanic unrest. Since the last update, there have been no significant changes in SO2 output. Emission rates for other gases were not measured due the lockdown from COVID-19. Seismic activity remains at lower levels and continues to fluctuate over periods of hours or days. ... [подробнее]
