Description: From Stanley-Brown (1899): "One unusually favorable day in August, 1892, Mr. Charles H. Townsend, of the United States Fish Commission, and I climbed one of the peaks of Unalaska bay, which brought Akutan in full view. To our great surprise, we saw gigantic rings of smoke, such as sometimes come in miniature from the smokestacks of locomotives, issuing from the crater at regular intervals of about twenty minutes. As each succeeding ring appeared, its predecessor was slowly breaking up and fading away in the air. Four such rings were seen, but how long the display lasted it was not possible to determine, as the peak became obscured in drifting banners of fog."
Jacob and Hauksson (1983) additionally list that this eruption had explosions that were heard 30 miles away, plumes to 1000' feet high on September 23, and earthquakes.
