On the morning of 5 May 1996, Qantas Airlines reported "smoke" over Sumatra near Sorikmarapi to just above 10 km altitude. However, in a satellite pass about 2 hours earlier there was no evidence of an eruption.

Geological Summary. Sorikmarapi is a forested stratovolcano with a 600-m-wide summit crater containing a lake and substantial sulfur deposits. A smaller parasitic crater (Danau Merah) on the upper SE flank also contains a crater lake; these two craters and a series of smaller explosion pits occur along a NW-SE line. Several solfatara fields are located on the E flank. Phreatic eruptions have occurred from summit and flank vents during the 19th and 20th centuries.
