Mount Awu (Indonesian: Gunung 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.

[2] The hazardous nature of the volcano is determined from the continuous lava source driven by the geodynamic setting (a double subduction line that creates an arc–arc collision) and the presence of a crater lake, sustained by the consistent rainfall on the island, on top of a lava dome.

[2] This setting creates the conditions for water injection in the lava dome, which can cause a water-magma explosion.

[2] A 4.5 km wide crater is found at the summit and a deep valley forms a passageway for lahars, splitting the flanks from the crater.
