Cerro Hudson, 1991

The Chilean volcano erupted in two separate, partially sub-glacial phreato-plinian cycles, the first beginning at 18:20 CLT on 8 August and the second at 12:00 CLT on 12 August. The second cycle, which ran from 12 to 15 August, produced a column 18 km high. Tephra fall-out clogged a river and caused it to spread out over more than a mile in width, and the combination of water and toxic ash content killed thousands of trees and the fish.
