The effusive-explosive eruption at the volcano continues.

Near-frequent strombolian and intermittent larger vulanian-type explosions continue to take place from the summit vent. The PVMBG surveillance cameras observed two eruptions over the past 24 hours. Grey-to-black ash plumes rose approx. 600-700 meters above the summit and drifted towards the northwest.

From the latest satellite image acquired on 18 May, the lava continues to keep the flow active on the eastern flank.

The local volcano observatory reported seismic signals with a maximum amplitude of 37.1 mm and a duration of 60 seconds.

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.
