A shallow lake partially fills the summit crater of Awu volcano in this 1995 view. Gunung Awu volcano, one of the deadliest in Indonesia, is cut by deep valleys that form passageways for lahars dissect the flanks of the 1320-m-high volcano. Powerful explosive eruptions in 1711, 1812, 1856, 1892, and 1966 produced devastating pyroclastic flows and lahars that caused more than 8000 fatalities.

The massive Gunung Awu stratovolcano occupies the northern end of Great Sangihe Island, the largest of the Sangihe arc. Deep valleys that form passageways for lahars dissect the flanks of the volcano, which was constructed within a 4.5-km-wide caldera. Powerful explosive eruptions in 1711, 1812, 1856, 1892, and 1966 produced devastating pyroclastic flows and lahars that caused more than 8000 cumulative fatalities. Awu contained a summit crater lake that was 1 km wide and 172 m deep in 1922, but was largely ejected during the 1966 eruption.

영어 요약

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.
