The eruptive activity at the volcano continues.
The latest satellite image from 16 June confirms a continuing thermal anomaly, indicating that viscous, gas-poor lava is still oozing onto the western slope of the 2020 cinder cone, extending beyond the caldera rim. The attached animation indicates that the lava flow has not advanced significantly over the past few weeks.
The southern lava flow arm, which traveled on the southern flank from mid-February until mid-April, is no longer active, i.e., no thermal signal has been detected in satellite images. The sluggish-paced viscous lava has been filling the main caldera mostly within one year. The new cinder cone started to grow in 2020 within the caldera, which has been constructed by the constant layering of lava flows and tephra. The cone is currently high about 400 meters.
Occasional strombolian-type explosions continue to take place from the crater within the main caldera. The last reported ash emissions have been reported on 27 May when grey ash plumes rose to 6,000 ft (1,8 km) elevation and drifted west.
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.
