Overview

Teon, an elongated andesitic island volcano in the southwestern Banda arc, is also known as Serawerna, the name of its active crater. Another smaller crater is located to the NNE of Serawerna. Explosive eruptions have been recorded since the 17th century; the largest produced pyroclastic flows and surges in 1660 CE that caused damage and fatalities.

Volcanic Hazards & Risk Assessment

Primary Hazards

  • Pyroclastic flows

Regional Volcanic Activity
The Sunda-Banda Volcanic Regions contains multiple active volcanic systems. Cross-regional magma interactions and tectonic stresses can influence eruption patterns across the entire arc. Monitor regional seismic activity and volcanic alerts.

About the Photo

Teon Island, seen here from the south, is a roughly 15-km-wide island in the western Banda Sea. The 655-m-high forested summit rises 3700 m above the sea floor. Explosive eruptions, the most severe of which was in 1660, have been recorded since the 17th century from Teon (also known as Serawerna).
