The Ghost Island of the Caspian Sea: A Transient Wonder of Nature
We frequently enough think of land as a permanent fixture, the solid ground beneath our feet. but the reality is far more dynamic, especially in places like the Kumani Bank mud volcano, also known as Chigil-Deniz, located 15 miles off the coast of Azerbaijan in the Caspian Sea. Here, the earth is anything but static.
Recently, the NASA Earth Observatory released a series of striking images captured by the Operational Land Imager (OLI) and OLI-2 instruments aboard the Landsat 8 and Landsat 9 satellites. these images document the birth and rapid decay of a new island, a phenomenon that underscores the ever-changing nature of our planet.
The Birth of a Ghost Island
Table of Contents
In November 2022, the underwater mud volcano was entirely submerged, with no land visible above the water. Though, following an eruption in early 2023, a new island emerged. The second image, taken between January 30 and February 4, 2023, shows the island at its peak, measuring approximately 1,300 feet (400 meters) across. A plume of sediment stretched for miles, a testament too the volcanic activity beneath the surface.
The Island’s Fleeting Existence
By the end of 2024, the island had nearly vanished. The third image reveals only a faint dot where the landmass once stood. This rapid erosion is a stark reminder of the power of natural forces. As the NASA Earth Observatory noted, this is not the first time the Kumani Bank has given rise to such a “ghost island.”
The Science Behind the Phenomenon
Mud volcanoes like Chigil-Deniz are formed by the eruption of mud, water, and gases from beneath the Earth’s crust.These eruptions can create temporary landforms, but they are often short-lived due to the relentless action of waves and currents. The caspian Sea, the world’s largest inland body of water, is particularly prone to such geological activity.

Why This Matters
The transient nature of the kumani Bank island offers a fascinating glimpse into the dynamic processes shaping our planet. It also highlights the importance of satellite technology,such as the Landsat program,in monitoring these changes.
As we continue to study these phenomena, we gain a deeper understanding of Earth’s geological activity.For more insights into the Caspian Sea and its unique features, explore the latest research from the NASA Earth Observatory.

The Kumani Bank may be a fleeting presence, but its story is a lasting testament to the ever-changing nature of our world.Satellites Spot a Ghost Island: The Mysterious World of Mud Volcanoes
In a fascinating finding, satellites have captured the formation of a “ghost island” created by a mud volcano. This phenomenon, while rare, is not entirely new. The mud volcano in question has a history of eruptions dating back to May 1861,when the island it formed was just 285 feet (87 meters) wide and 11.5 feet (3.5 meters) above the water. The largest island emerged after an eruption in 1950, measuring 2,300 feet (700 meters) wide and 20 feet (6 meters) high.
Mud volcanoes, described by University of Adelaide geologist Mark Tingay as “weird and wonderful features that remain largely understudied and little understood,” are formed when underground pressure forces hot fluids, gases, and sediments to the surface.These geological marvels are not limited to Earth. Scientists have identified similar formations on Mars, where circular mounds in the northern lowlands are believed to be akin to mud volcanoes.
On Earth, Azerbaijan boasts an unusually high concentration of these features, with more than 300 located around and off the east coast of the country, near the Kumani Bank. This region has become a hotspot for researchers studying these enigmatic structures.
To better understand the scale and history of these mud volcanoes, here’s a summary of key eruptions:
| Year | island Width | Island Height |
|———-|——————|——————-|
| 1861 | 285 feet (87 m) | 11.5 feet (3.5 m) |
| 1950 | 2,300 feet (700 m)| 20 feet (6 m) |
The discovery of these formations on both Earth and Mars highlights the interconnectedness of geological processes across planets. as researchers continue to study these “weird and wonderful” features, they may unlock new insights into the dynamic forces shaping our world and beyond.

Interview with Dr. Elena Petrova, Geologist and Mud Volcano Expert
The Birth of a ghost Island
Senior Editor: Dr. Petrova, can you describe how this ghost island in the Caspian Sea came to be?
Dr. Petrova: Certainly. In early 2023, the underwater mud volcano known as Chigil-Deniz erupted, pushing mud, water, and gases to the surface.This material accumulated and formed a new island measuring approximately 1,300 feet across.The eruption also created a visible sediment plume that stretched for miles.
The Island’s Fleeting Existence
Senior Editor: Why did the island disappear so quickly?
Dr. petrova: The island was primarily composed of loose sediment, which is easily eroded by the waves and currents of the Caspian Sea. By the end of 2024, the island had nearly vanished, reduced to just a faint dot. This rapid erosion is typical of mud volcano islands, which are often short-lived.
The Science Behind Mud Volcanoes
Senior Editor: What exactly are mud volcanoes, and how do they form?
dr. Petrova: Mud volcanoes are formed when underground pressure forces a mixture of mud, water, and gases to the surface. They can create temporary landforms,but these are usually unstable and quickly eroded. The Caspian Sea, with its unique geological setting, is particularly prone to such activity.
