What's Happening?
Deception Island, located in the South Shetland Islands of Antarctica, is a geologically active site with a history of over 20 eruptions in the past 200 years. The island's unique geomorphology, defined by a major volcanic eruption, has resulted in the formation of Port Foster, a sea-flooded caldera. Recent research efforts have focused on mapping this area using UAV-based LiDAR technology. The study, conducted between January 29th and February 3rd, 2025, utilized advanced equipment to capture detailed topographic data. The island hosts Argentine and Spanish research stations, which have been operational every Antarctic summer since 1989. The geothermal activity on the island, characterized by fumarolic emissions and heated ground, attracts approximately 30,000 tourists annually. The island is also home to diverse bryophyte communities and penguin colonies, adding to its ecological significance.
