Overview

The andesitic Wurlali stratovolcano was constructed at the northern end of a 5-km-wide caldera on the eastern side of Damar Island in the Banda Sea. Fumarolic activity occurs in the two summit craters and on the SE flanks, producing exploitable sulfur deposits. An explosive eruption was observed in 1892 CE.

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

Wurlali volcano (also referred to as Damar), seen here from Cape Wilhelmus on the north, is part of Indonesia’s Banda Island chain. The stratovolcano was formed in the northern part of a 5-km-wide caldera. During historical time only a single explosive eruption occurred in 1892 from the summit crater.
