From Wikipedia

Mount Awu is the largest stratovolcano in the Sangihe Islands chain, located on Sangir Island in North Sulawesi, Indonesia. Powerful eruptions have occurred in 1711, 1812, 1856, 1822, 1892, and 1966 with devastating pyroclastic flows and lahars that resulted in 11,048 fatalities. A total of 18 eruptions are recorded from 1640, with two of VEI 4 and 3 with VEI 3, one eruption every ~ 20 years. The hazardous nature of the volcano is determined from the continuous lava source driven by the geodynamic setting and the presence of a crater lake, sustained by the consistent rainfall on the island, on top of a lava dome. This setting creates the conditions for water injection in the lava dome, which can cause a water-magma explosion.
