AVO Image

High-resolution midday Planet imagery from March 7, 2021 showed ash emissions coming from the intracaldera cone at the same location as the 2018 vent. Tephra deposits extend at least 22 km SE and about 14 km NE. There is a flank vent 1 km to the east of the active cone where ice is melting/collapsing around an incandescent source, producing both steam and a meltwater lake (blue region). There is therefore ash erupting from the top of the cone and an incipient subglacial effusive eruption from a vent 1 km down the flank.
