Pyroclastic flows (gravity-driven mass flows) continue to occur from the actively growing lava dome.
Gravitational collapse of parts of the dome triggered block-and-ash flows that lifted ash plumes as it descended the SW and SE slopes.
The seismic station recorded about 120 volcano-tectonic earthquakes.
The current hazards are hot avalanches mobilized into hot glowing currents towards the south-southwest sector including Kali Kuning, Boyong, Bedog, Krasak, Bebeng, & Putih with a maximum distance of 5 km.
In addition, the eruption of volcanic material in the event of an explosive eruption could reach a radius of 3 km from the summit.

Activity continues as the lava dome slowly grows and sheds numerous glowing avalanches that descend into Kali Krasak ravine on the western flank. During yesterday, the volcano observatory counted 126 avalanches alone. Read all
