Deception Island is an island in the South Shetland Islands archipelago, with one of the safest harbours in Antarctica.

This island is the caldera of an active volcano with a submerged base diameter of approximately 30 km, rising up to 1.5 km above the sea floor. The volcano seriously damaged local scientific stations in 1967 and 1969. The island previously held a whaling station; it is now a tourist destination and scientific outpost, with Argentine and Spanish research bases. While various countries have asserted sovereignty, it is still administered under the Antarctic Treaty System. [Wikipedia]
