Penguins live on these volcanos, and the Sandwich plate is like a cork on the East side of the Scotia plate. This is where fault lines between three techtonic plates converge.
Wiki "Map of South Sandwich Plate (SAN) shows its position between the Scotia Plate (SCO), South American Plate (SAM) and the Antarctic Plate (ANT). There are also visible The East Scotia Ridge (ESR), South Sandwich Islands (SSI) and the South Sandwich Trench (SST)." )
