The low-level eruptive activity at the volcano continues.
The AVO detected elevated surface temperatures and small-amplitude infrasound detections have been occurring. The seismic tremor keeps elevated levels but started to decline over the past eight hours. Ash emissions or deposits haven’t been observed outside the crater in satellite images.
The volcano entered another 12th eruptive period, commencing yesterday and is still continuing at the time of this update. Whether the activity sharply increases or not is not clear yet, but based on previous eruptive sequences, the activity may culminate in a strong fountaining period (so-called paroxysm) and ash-rich emissions.
The alert level for the volcano remains at Orange.
