Positioned roughly 105 kilometres from mainland Antarctica, the island is famous for its geological and ecological significance, in line with experiences.
Geological Formation and Volcanic Exercise
Studies state that the caldera was shaped throughout one in every of Antarctica’s largest eruptions, estimated to have ejected 30 to 60 cubic kilometres of magma and ash.
