Description: Jaggar (1929) writes that an island trapper reported that between 1906 and 1911, Pavlof smoked vigorously, and "sometime in 1911 'fire' poured down the mountain and alarming rumbles continued for several months. Bowlders were thrown into the air. The mountain was reported to have cracked open toward the north, * * * observers on the island of Unga report that an alarming roar was heard, waxing and waning, on the night of December 6-7 1911, between 8pm and 4am, and that the noises were heard for four days. A series of earthquakes was recorded on December 31, 1911 at 12:45, 6, and 7:15am, and at 8:45 pm at Unga." Unga is approximately 55 miles away from Pavlof.
McNutt (1985) writes that this is the most powerful historic eruption of Pavlof.
