The eruptive phase at the volcano has continued throughout yesterday.
Given the previous paroxysm series characterized by tall and dense ash columns, emissions have been reaching only a low-level altitude of about 16,000 ft (5 km) moving northeast. The National Weather Service has issued a SIGMET for this ash cloud.
The 7th such episode from the volcano’s summit vent took place within the past month.
