Landslides and steam emissions triggered by earthquakes

Landslides and steam emissions on Wurlali volcano were triggered by MM IV-V earthquakes near the [island]. About 4,000 people fled the area, and one of the evacuees died of shock. Staff from VSI observed small landslides and cracks in house walls. There was no volcanic activity observed following the landslides, but the usual white plumes continued to rise 30-50 m above the crater. Tectonic earthquakes were continuing at rates of 14-32/day on 8 February.

Wurlali volcano, also known as Damar, is the SW-most historically active volcano in the Banda arc. The 868-m-high andesitic 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. An explosive eruption in 1892 is the only known historical activity.

Wurlali volcano (also referred to as Damar), seen here from Cape Wilhelmus on the north, is part of Indoneisia's Banda Island chain. The 868-m-high stratovolcano was formed in the northern part of a 5-km-wide caldera, and has twin summit craters. During historical time only a single explosive eruption occurred, in 1892 from the summit crater.

Steam issues from the sulfur-encrusted Wurlali fumarole field, which is a source of sulfur extraction. Fumarolic areas at Wurlali occur in the summit crater and on the SE flank.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.
