description Deception Island fumaroles Overview

Deception Island is an active volcano in Antarctica's South Shetland Islands with a flooded caldera known as Port Foster. The island features geothermal fumaroles that vent steam and heat directly onto the beaches. These thermal anomalies create localized areas of warm sand and water in an otherwise freezing polar environment, attracting both scientific researchers and visiting tourists who dig shallow pools in the shore. The fumaroles are a visible reminder of the ongoing volcanic activity beneath the surface.
