Description: From Kienle and Swanson (1985): "A photograph taken during the [earthquake] swarm by Austin Post of the U.S. Geological survey on September 3 shows a strong plume fed by very active fumaroles on the 1964 lava dome. A small ash eruption and incandescence (red glow) on the flank of the volcano was seen during the late evening twilight of October 7 from a fishing boat 38 km north of the volcano. The eruption is corroborated by seismic tremor, which was recorded on both of the then existing seismic stations between 23 and 01 hours on October 7/8."

Waitt and Beget also describe this event: "In September-October 1971 billowing fumaroles and a report of incandescence followed an earthquake swarm within the volcanic cone in late August and early September (Kienle and Swanson, 1980, 1985, p. 25-28)."
