Description: Miller and others (1998) "Coast and Geodetic Survey personnel recorded renewed activity on Kiska Island in early September, 1969; an ash column was observed rising to 400 m and steam to 4000 m. "Flames" and what appeared to be lava were reportedly visible from Amchitka, 80 km distant. On September 16, strong sulfur odors, air temperatures elevated by 10 to 15 degrees C, and possible evidence of a small lava flow were noted during a military flight over north Kiska Island (Smithsonian Institution, 1969; eyewitness accounts on file at Geophysical Institute, University of Alaska, Fairbanks.)"

Smithsonian Institution, 1969, CSLP Card 0751: (12 September 1969) Ash to about 1,200 feet and steam plumes to about 12,000 feet and lava seen; source uncertain

Smithsonian Institution, CSLP Card 0752: (17 September 1969) Overflights identify Kiska as source of activity
