SEGUAM ISLAND (Alaska)
United States of America
Seguam Island is made up of several stratovolcanoes in the Andreanof Islands group in Alaska’s Aleutian Islands. The island contains two calderas, one of them having erupted as recently as 1993. The mountainous oval-shaped island covers an area of just over 200 square kilometers or 80 square miles. The stark beauty of this remote island is offset by the chilly surrounding waters known for occasional whale sightings.
