There are numerous festivals and rituals associated with the volcano and its surrounds.

Inflation was noted in August along with an earthquake swarm 10 km SE 3 – 6 August that may or may not have been connected with magmatic activity. The fountains and continuing explosions fed incandescent rockfalls around the summit.
