Description: From Smithsonian Institution (1984): "Eruptive activity resumed on 29 November [1984]. At about 0400, Perryville residents were awakened by rumbling noises from the volcano. By 0800, a black ash cloud was rising to about 3.5-4 km altitude. At 1000, a second plume rose to about 4 km, followed by smaller bursts that were occurring at approximately 5-minute intervals as of about 1020. Pilots reported an ash plume to about 4.5 km altitude at 1045, very little activity at 1100, and another ash plume to about 5.4 km at 1115. No incandescent material was observed from Perryville or by the pilots.

"A pilot who flew over the volcano on the morning of 5 December reported a white vapor plume, containing only a small amount of ash, rising from two small pits on the E side of the previously active cone. One of the pits was steaming more vigorously than the other, and a brownish haze drifted downwind from the volcano. He observed no incandescent material or recent lava extrusions. On 6 December, Perryville residents observed large vapor plumes of varying intensity that contained very minor amounts of ash. They saw no incandescent material, and had heard no rumbling noises during the previous several days. On 7-8 December the volcano was obscured by weather clouds; however, small intermittent vapor plumes with no ash were observed from Perryville on the 9th. No incandescent material was seen. On the 10th and 11th, the volcano was not visible from Perryville."
