Augustine eruption leads to updated model
by Lorien Nettleton, Arctic Region Supercomputing Center
A massive eruption cloud ascended from Redoubt volcano on April 21, 1990. The mushroom-shaped plume spread upward from avalanches of hot debris--pyroclastic flows--that cascaded down the north flank of the volcano. A smaller, white steam plume rose from the summit crater.
