Geological summary

Karangetang (Api Siau) volcano lies at the northern end of the island of Siau, about 125 km NNE of the NE-most point of Sulawesi. The stratovolcano contains five summit craters along a N-S line. It is one of Indonesia's most active volcanoes, with more than 40 eruptions recorded since 1675 and many additional small eruptions that were not documented (Neumann van Padang, 1951). Twentieth-century eruptions have included frequent explosive activity sometimes accompanied by pyroclastic flows and lahars. Lava dome growth has occurred in the summit craters; collapse of lava flow fronts have produced pyroclastic flows.

From Wikipedia

Karangetang, also known as Api Siau is a volcano on the north side of Siau Island off the coast of Sulawesi, Indonesia. The island covers 160 km2, and had 46,459 inhabitants in mid 2023. It is one of the most active volcanoes in Indonesia, having erupted 41 times since 1675. A pyroclastic flow in 1997 killed three people. Karangetang is the tallest mountain in offshore North Sulawesi, at 1827 meters above sea level.
