Volcanic Risk

Two million chinstraps nest on the volcanic Zavodovski Island.  This is the largest penguin colony in the world.  The heat from the crater keeps the slopes free of ice and snow, so the penguins can nest earlier than those farther south.  They have one of the worlds most dangerous central heating systems.
