The eruptive activity continues.
The volcano’s behavior is characterized by a combination of near-constant moderate and sporadic strong vulcanian-type explosions from the caldera’s cinder cone over the past several weeks.
A stronger-than-usual explosion took place from the volcano’s cinder cone at 09:13 local time this morning. A spectacular grey ash-laden plume reached up to 10,900 ft (3,300 m) altitude and extended towards the west and southwest.
The volcano observatory reported a seismic signal with a maximum amplitude of 48 mm and a duration of 178 seconds.
The continuing lava dome is actively growing as viscous magma continues to rise into it and form a faint glow on the top of the dome. Thus, it extrudes lava dome blocks into slowly advancing lava flow (so-called coulée) on the northern flank.
In order to mitigate risk, people are advised to avoid the area within a radius of 2 km and 3.5 km from the crater.
