The effusive-explosive eruption at the volcano continues.
Strombolian and occasional larger vulcanian-type explosions continue to take place from the cinder cone within the main caldera. The PVMBG surveillance cameras observed three eruptions over the past two days. Grey and grey-to-black ash plumes rose approx. 500-700 meters above the summit and drifted towards the west and northwest of the volcano.
The local volcano observatory reported seismic signals with maximum amplitudes of 18.2, 34.2 and 20.2 mm and durations of 36, 216 and 192 seconds.
The lava flow at the volcano continues to be active mainly within the caldera, as seen in the attached image processed by the Sentinel-2. The outer eastern 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.
