KarangetangAbout Karangetang
Karangetang (also known locally as Api Siau) is an active stratovolcano on Siau Island in North Sulawesi, Indonesia. It is among the archipelago’s most persistently active volcanoes and is monitored closely by Indonesian authorities.
The volcano rises from the northern end of Siau Island and has produced frequent eruptions in the 20th and 21st centuries, including lava flows and explosive events that have affected settlements on the island. Access to lower slopes is possible from local coastal communities, but activity can make the mountain hazardous for visitors.
Situated in the Sitaro Islands group, Karangetang dominates the small island’s landscape and is visible from nearby sea routes and neighbouring islands.
- Activity: One of Indonesia’s most active volcanoes; eruptions often produce lava flows, pyroclastic activity and ash that can force local evacuations on Siau Island.
