The powerful eruptive activity at the volcano goes on.
Stronger-than-usual explosions continue to be observed from the cinder cone within the summit caldera. At midnight last night, a tall, dense grey ash column could be seen rising to estimated 3,300 meters (10,800 ft) height towards the southeast. In addition, several minutes before the eruption, a vivid night-time glow accompanied an explosion, which might suggest a new magma influx to the volcano’s feeder pipe.
The seismic network reported signal with maximum amplitudes of 28 mm and a duration of 186 and 130 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.
