The Devil's Pond in the city of Covasna, a unique monument in Europe.

Introduction

Even though it has invaluable cultural significance, the "Devil's Pond" in Covasna is not well-known to many people. In fact, "Devil's Pond" is a mud volcano, meaning it is a pit where mud eruptions occur constantly. Interestingly, this volcano is located right in the center of Covasna.

The Phenomenon

The phenomenon occurs due to the release of carbon monoxide, researchers explain. This happens because of the numerous volcanic eruptions that took place in the Harghita region over two million years ago. Studies conducted at "Devil's Pond" show that the carbon monoxide in the bubbles that rise to the surface ranges from 95% to 98%.

Historical Significance

The name "Devil's Pond" seems to have been used since the 18th century. People believed that the clayey water was boiling due to fire from hell; however, the actual volcanoes have long ceased to pose a danger, having been extinct for several decades.
