"Smoke":
Central eruption:

Description: From Miller and others (1998): "Records of volcanism on Semisopochnoi Island are scant; historical eruptions could have involved the small Lakeshore Cone and Sugarloaf cone in addition to Mount Cerberus [Mount Young]. However, since at least one of the early reports specified that the activity noted was in the center of the island, and Mount Cerberus is the least eroded of the recent cones, it is believed to have been the source of most recorded events (Coats, 1950; 1959)."

From Grewingk (1850, translated 2003 by Fritz Jaensch): "1772, Semisopochnoi smoking."
