Answer: Azerbaijan
Notes: The Kumani Bank mud volcano erupted in 2023, creating a temporary "Ghost Island." Kumani Bank mud volcano is located 25 km off Azerbaijan’s eastern coast in the Caspian Sea. The island, about 400 meters across, formed in 2023 and eroded back into the sea by late 2024. Ghost Islands are temporary land masses created by volcanic activity that disappear over time. The island provides geological insights into tectonic processes and subsurface pressure dynamics. It offers clues about similar features on Mars for planetary exploration. The area is linked to methane and gas emissions and highlights Azerbaijan’s unique geological landscape with over 300 mud volcanoes.
