Soputan is an active stratovolcano on the island of Sulawesi in northern Indonesia, characterised by a steep conical profile and frequent eruptive activity in the 20th and 21st centuries. It is one of the more active volcanic centres in North Sulawesi and is monitored for eruptions and ash emissions.

The volcano rises prominently above surrounding terrain and is a focus for scientific monitoring and civil-protection measures due to its periodic explosive eruptions. Volcanic activity commonly produces ash plumes and short-lived lava or pyroclastic activity that can prompt local evacuations.

Soputan has been the site of repeated modern eruptions recorded by Indonesian observatories, and warnings are issued when activity increases. Access to the upper slopes is often restricted during periods of unrest.

Soputan sits in North Sulawesi on the Minahasa Peninsula in northern Sulawesi, Indonesia, and is visible from nearby towns and roads that serve as bases for researchers and local authorities.

  • Volcanic activity and hazards: The volcano is frequently monitored and issues ash and eruption warnings; ash fall can affect nearby communities and air traffic in the region.
