An ash-bearing plume rises above Sabancaya volcano in this photo taken from the NE, possibly in October, 1988. Voluminous steam plumes, some with dark, basal "rooster-tails," were observed to have risen 0.5-1 km above the summit on June 22, 1988. The northern flank of Ampato volcano rises at the far right.
