Description: Stone and Kienle (1975) report: "An eruption of the Pavlof Volcano was observed at 10:00 p.m. local time 12 November (0800 GMT 13 November) from a location some 33 km from the summit. The observers reported seeing 'shooting flames,' coupled with a possible lava flow down the northwest flank.

"A seismometer located 7 km southeast of the summit recorded increased micro-earthquake activity coincident with the time of the reported lava eruption.

"Seismic records showed onset of harmonic tremor on 13 November, 07:00 AST, coincident with the reported eruption of lava."

McNutt (1985) estimates the total dense rock equivalent volume of eruptive material for this eruption as 4.8 - 7.9 x 10^6 cubic meters. McNutt (1999) estimates the total dense rock equivalent volume of eruptive material for this eruption as 6.4 x10^6 cubic meters.
