Protector Shoal is a submarine volcano, also called seamount, which rises gently from an ocean depth of 3,937 below sea level to about 89 feet below sea level, 35 miles northwest of Zavodovski Island in the South Sandwich Islands chain, at 55°54'S 28°6'W.
The seamount's last eruption occurred during March 1962. Protector Shoal is the only volcano in the arc that has erupted rhyolite pumice.
