Andernach Geyser

Andernach Geyser

We are generally familiar with hot geysers, which spout steam and hot water, but in contrast, there also exists a cold geyser in the world — the Andernach Geyser. This mysterious geyser is located in the town of Andernach in the county of Mayen-Koblenz, Rhineland-Palatinate, and its name is derived from the name of the town.

The power behind the Andernach Geyser comes from underground cold water and carbon dioxide, with the CO₂ originating from the nearby Eifel Mountains. In 1903, this astonishing cold-water geyser was discovered when people were drilling for mineral water. When deep underground — several hundred meters down — carbon dioxide meets cold water, the low temperature and high pressure force large amounts of cold water to rapidly seek out fissures. This pressurized water then bursts upward like shaken soda water, erupting through cracks in the earth's surface, thus forming the famous Andernach Geyser.

The Andernach Geyser can shoot water jets up to 64 meters high, with the white plume shooting straight into the sky — a truly spectacular sight. Unfortunately, this geyser is not open to the public. Only the Andernach city government is permitted to periodically open the geyser vent to let this “sleeping giant” release some pent-up pressure.
