In a magnitude four eruption on the volcanic explosion index (VEI) in 1778, 15 people were killed by volcanic bombs . The upper third of the volcano is said to have been destroyed in the eruption. The outbreak of 1924 was also magnitude four. On the morning of June 22, 2019, there was a Plinian eruption with a 17 kilometer high ash cloud .
