The effusive-explosive eruption of the volcano continues at low levels.
The latest clear high-resolution satellite imagery from 7 March shows that the activity of the volcano continues from two vents – cone within the summit caldera (same location as the 2018 eruption vent) and flank vent on the east slope in the inner glacier-filled caldera known as flank-to-lateral eruption.
The explosive activity from the cone in the summit caldera continues at lesser, but near-constant intensity and generates ash emissions that reached 11,000 ft (3,400 m) altitude spreading about 22 km to the SE and about 14 km to the NE of the volcano.
The lateral effusive eruption, indicating magma-filled dyke intersected the surface, continues to be active from the eastern flank vent at about 1 km distance from the summit cone. An emitting lava flow causes phreatic-phreatomagmatic explosions at interaction with snow, ice and water. A gas-steam plumes rose to an estimated 3,5 km altitude.
Both vents are producing ash and gas-steam emissions at the same time as can be seen in image below.
