Syneruptive collapse of a kilometer-deep caldera took place atop Mount Katmai, a stratovolcano centered 10 km east of the eruption site at Novarupta, owing to drainage of magma from beneath the Katmai edifice. Petrological correlation of the sequence of deposits near Novarupta with ash layers at Kodiak village, 170 km downwind, where three episodes of ashfall were recorded (to the hour), provides key constraints on timing of the eruptive events. This was a place once covered in shrubs and tundra and frequently traveled by Alutiiq people. Volcanic dust and sulfur-based aerosols released into the stratosphere can absorb incoming solar radiation, resulting in cooler than average summer temperatures and warmer than average winters for one or more years following an eruption.
