Activity has decreased significantly during the past days. Since 2 am local time on 27 May, RSN has detected a substantial and abrupt decrease in the level of seismic activity, which also marks the end of the most recent period of frequent, moderate ash emissions.

During the past days, seismic activity has been dominated mainly by small low-frequency volcanic earthquakes and harmonic tremors of very low energy and short duration, reflecting internal fluid movements.
When not obscured in clouds, only a steam plume can be seen emerging from the active crater. No recent ash falls or sulfur smells in the Central Valley have been reported.
