The effusive-explosive eruption at the volcano continues.

Strombolian explosions continue to take place from the cinder cone within the main caldera. The PVMBG surveillance cameras observed another eruption yesterday. A white-to-grey ash plume rose approx. 500 meters above the summit and drifted towards the southeast of the volcano.

The local volcano observatory reported a seismic signal with a maximum amplitude of 33.5 mm and a duration of 64 seconds.

The viscous lava flow continues to ooze out from the cone, advancing at a sluggish pace to the east, as seen in the attached image processed by the Sentinel-2. The outer eastern caldera flank seems to being stopped fed by lava for a long time.

The warning bulletin states that ballistic impacts of volcanic bombs and pyroclastic flows and lahars could affect an area of about 2 km distance from the main crater.
