Protector Shoal is a submarine volcano. The volcano erupted in March of
1962. The euption produced great volumes of rhyolitic pumice. The pumice
raft covered an area of at least 2,000 square miles! Pumice from the
eruption eventually drifted west to New Zealand. Unlike most of the South
Sandwich Islands, which are made of basalt, Protector Shoal is the only
volcano in the arc that has erupted rhyolite.
