The elevated activity may signal increased fluid movements of gas, water and possibly magma under the surface at about 2 km depth.
Surveillance cameras detected a sudden increase of carbon dioxide (SO2) emissions, but it has been decreasing throughout the day and is still declining at the time of this update.
The alert level for the volcano remains at Yellow.
