Sangeang Api

Sangeang Api is an active volcano on Sangeang Island in the Lesser Sunda Islands of Indonesia. The cone is one of several active volcanic centres in the Indonesian archipelago.

The volcano has produced explosive eruptions in recent decades, generating ash plumes and local disruption. Its activity is monitored due to potential impacts on local communities and aviation.

Because of its location in a populated volcanic region, significant eruptive episodes have prompted aviation notices and temporary restrictions on access to the island and surrounding waters.

Sangeang Island lies north-east of Sumbawa in the province of West Nusa Tenggara, Indonesia, positioned among the string of islands that form the Lesser Sunda chain.

• Hazards: Known for intermittent explosive activity; eruptions can produce ash plumes that affect air travel in the region.

• Treat Sangeang Api as an active volcano: always check the Indonesian Center for Volcanology (PVMBG) activity level and aviation/ash advisories before planning any approach.
• If you want a close view, join an experienced local boat or aerial operator based in Sumbawa - access is by sea or charter only and operators will refuse approach when alerts or ash fall are active.
• Do not attempt landings during periods of unrest; even when quiet, expect sudden changes in ash or gas emissions so plan flexible travel and monitor local updates.
