An E-flank fissure located 5 km from the summit produced an incandescent lava flow during 10-14 May 1978 that traveled 6 km to the Pandi River. Explosive activity took place from the summit crater of Ulawun over 7-13 May, accompanied by pyroclastic flows from a fissure high on the SE flank on 9 May. At least a dozen vents were active during this eruption.
