Awu Volcano, located on the northern end of Sangihe Island, Indonesia, is a highly active stratovolcano within the Sangihe volcanic arc. This complex geological setting, influenced by the subduction of the Molucca Sea plate beneath the Eurasian plate, drives Awu’s frequent and often explosive eruptive behavior. Historical records document significant eruptions characterized by devastating pyroclastic flows, lahars, and extensive ashfall (e.g., 1711, 1812, 1856, 1892, 1966), resulting in substantial loss of life

2024: Level III (Alert)


Awu’s Eruptive History

Year Eruptive Activity
1640 Phreatic eruption, likely driven by steam explosions due to groundwater-magma interaction.
1711 Major eruption (VEI 4) characterized by pyroclastic flows, lahars, and likely the formation of a summit caldera.
1812 Major eruption (VEI 4) with extensive pyroclastic flows, significant casualties, and possible tsunami generation.
1856 Large phreatomagmatic eruption (VEI 3) caused by the violent interaction of magma with water, generating significant casualties.
1892 Large phreatomagmatic eruption (VEI 3), likely triggered by the presence of a crater lake, causing casualties.
1966 Major eruption (VEI 4) producing pyroclastic flows, lahars, and impacting the island’s population.
2004 Eruption with lava dome formation, potential for phreatic or phreatomagmatic explosions, and ash emissions.
2024 The Alert Level is increased to Level III (Alert). Mt. Awu’s seismicity has been dominated by both shallow and deep volcanic earthquakes. SO2 is higher than normal and there has been steam rising off the lava dome.
