Temporary Ghost Island Emerges in Caspian Sea

NASA satellites captured the emergence and disappearance of a temporary island in the Caspian Sea.

NASA Discovers Temporary Island in Caspian Sea Created by Mud Volcano

A temporary volcanic island emerged and quickly disappeared in the Caspian Sea following an underwater eruption near Azerbaijan’s coast. Captured by NASA satellites, this 'ghost island' was formed by the Kumani Bank mud volcano in early 2023. Measuring about 1,300 feet wide, the island was a fleeting display of nature's volatile forces and eroded back into the sea by late 2024. Mud volcanoes like Kumani Bank are driven by geothermal activity and typically create brief landmasses that can alter local environments but are unstable and short-lived.

The phenomenon of a 'ghost island' raises intriguing questions about the instability of geological formations. Unlike traditional volcanoes, mud volcanoes serve as a reminder of Earth's dynamic geology. The resurgence of temporary landmasses showcases not only the unpredictability of underwater eruptions but also highlights the ecological and scientific implications they bring, including potential impacts on marine ecosystems. Understanding these processes can provide valuable insights into tectonic activities in regions like Azerbaijan, which is particularly rich in geothermal phenomena.

Highlights

The emergence of these temporary landmasses continues to spark interest in geological studies worldwide.
