The explosive eruption from the volcano 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 few weeks.

Such above-average eruptions appeared at 14:05 and 14:35 local time yesterday and generated grey ash plumes rising about 1000 m above the crater. Ash emissions extended south-southwest.

The seismic network reported signals with a maximum amplitude of 28 mm and a duration of 85 and 203 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.
