OVSICORI-UNA recorded ash emissions during the past week which become near-continuous with plume that rose to an altitude of 11,614-12,600 ft (3,540-3,840 m).
Incandescence continues to be observed in the crater.
Tremor has not shown significant variations.
Sulfur dioxide (SO2) emissions are at stable level.
No thermal anomaly was observed in satellite images.

OVSICORI-UNA report that no ash emissions was detected from the volcano. Seismicity is of a stable amount. Carbon dioxide/Sulfur dioxide (CO 2 / SO 2) and Hydrogen sulfide/Sulfur dioxide (H 2 S / SO 2) ratios remain within a normal range. Sulfur dioxide emissions was measured at an average of 100 tonnes/day. Crater depth was measured at 140 m, compared to 220 m in 2019. This shallowing of the crater is due to “frequent collapses of the internal walls.” ... read all
