NASA satellites have captured the rare phenomenon of an island emerging from the Caspian Sea after a mud volcano erupted and then completely disappearing in less than two years, challenging scientists and revealing the unpredictable force of nature.
An island that appears out of nowhere and disappears as if by magic. That’s exactly what NASA satellites have captured in the Caspian Sea. This island, nicknamed “ghost,” appeared in 2023 and disappeared in 2024, leaving scientists puzzled about the geological forces behind this unique phenomenon.
What makes this story even more fascinating is the fact that the island was created by the eruption of a mud volcano, a rare feature and little studied. Let's explore this mystery and understand how NASA is helping to decipher Earth's secrets.
NASA finds apparition and disappearance of ghost island
It all started with an eruption of the Kumani Bank mud volcano, located off the coast of Azerbaijan. Mud volcanoes, unlike traditional volcanoes, spewed a mixture of mud, gas and sediment, forming the island. Within days, the landmass was visible from space, thanks to images captured by NASA's Landsat 8 and 9 satellites.

But why didn't such a quickly created island remain? This is the question that scientists are trying to answer by analyzing the geological dynamics and conditions of the region.
If the birth was impressive, the disappearance was equally dramatic. In less than two years, the island was completely eroded by winds, waves and tides, leaving only traces of the Kumani Bank above water. Nature proved his strength once again, showing that nothing is permanent, not even the earth.
What are mud volcanoes?
Mud volcanoes are curious geological phenomena formed by underground pressures that force out mud, gas and sediment. They are common in hydrocarbon-rich regions such as Azerbaijan and can create transient landscapes, such as the mysterious island in the Caspian Sea.
In the case of Kumani Bank, history is full of similar events. The island discovered by NASA is not the first; since 1861, the volcano has produced several ephemeral islands, always erased by the relentless forces of nature.
The science behind the phenomenon
The Caspian Sea is a tectonically active region where the Arabian and Eurasian plates collide, creating ideal conditions for mud volcanoes. This intense activity makes Azerbaijan one of the most studied places by geologists.
With the help of satellites, NASA has been able to track the life cycle of the 2023 island in detail, something that was impossible in the past. This not only helps to understand local phenomena, but also offers valuable clues about how tectonic forces shape our planet.
Risks and wonders of the phantom islands
While these islands are fascinating, like this one discovered by NASA, they also pose risks. Mud volcano eruptions can release large amounts of gas and sediment, threatening wildlife and even local infrastructure. Some previous eruptions have sent flames hundreds of meters into the air, highlighting the explosive power of these phenomena.
On the other hand, these ephemeral formations are a visual and scientific spectacle. They remind us that even with all the technology, there is still a lot to discover about our planet.
