GEOLOGIC HISTORY

Wurlali volcano, also known as Damar, is the SW-most historically active volcano in the Banda arc. The 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 twin summit craters and on the SE flanks, producing exploitable sulfur deposits.

Historic Activity: An explosive 2 day eruption in 1892 is the only known historical activity.

Recent Activity: Landslides and steam emissions on Wurlali volcano were triggered by MM IV-V earthquakes on Damar Island. There was no volcanic activity observed following the landslides, but white plumes, normal activity at the volcano, rose 30-50 m above the crater. Tectonic earthquakes were continuing at rates of 14-32/day on Feb. 8, 1993.
