Minor earthquakes were detected in the past day, but no significant activity was observed in satellite or webcam images due to cloud cover. The volcano remains under a 'WATCH' alert level and an 'ORANGE' aviation color code, indicating ongoing volcanic activity with potential for further eruptions.
