Description: From Shackleford (1982): "Pavlof experienced a strong Strombolian eruption in Nov. 1980. There was a very minor ash emission in early July, but the eruption proper began at 10:47 on 8 Nov. with a short burst from the vent high upon the NE flank. The main eruptive episode began in the pre-dawn hours of 11 Nov., activity waxing throughout the day. By early evening on the 11th, lava fountaining was rising 300 m over the volcano, while a lava flow advanced down the N flank (flow may be rootless and spatter-fed). During the night of 11-12 Nov. the vividly incandescent eruption was clearly visible from Cold Bay and Sand Point, and was likened to a big blowtorch in appearance. Strong activity lasted through 12 Nov., black ash plumes rising to 6 - 11 km above sea level. The eruption ended in the morning of 13 Nov. Strong harmonic tremor accompanied the Nov. eruptions."

McNutt (1999) calculates an eruptive volume of 6.1 x10^6 cubic meters (dense rock equivalent) for this eruption.
