Volcano in the Netherlands: Zuidwal volcano
The Netherlands has a volcano! A real stratovolcano, located more than 2 kilometers below the earth’s surface, under the Wadden Sea and between the Wadden island of Vlieland and the Frisian city of Harlingen. To the west of the island of Griend there is a very special natural phenomenon for the Netherlands: the Dutch volcano, the Zuidwal volcano. The top of the Dutch volcano was discovered in 1970 during a drilling in the Wadden Sea for gas fields. When was the Dutch volcano active?
A volcano in the Netherlands?
The volcano found in the Dutch Wadden Sea is a dead volcano. It is literally buried in the surface of the Wadden Sea, a fire-eater that will never erupt again. The Dutch volcano was about 1000 meters high and had a circumference at its base of about a few kilometers.
Active years Zuidwal volcano
Despite the fact that the Dutch volcano is no longer active, this Zuidwal volcano has been active for 12 million years. The South Wall Volcano was active during the late Jurassic (about 160 to 145 million years ago, the age of the dinosaurs). The eruptions and eruptions of the Dutch volcano were characterized by short and violent eruptions, with many explosions. Despite the fact that it is now a dead volcano, the temperature around the volcano in the Wadden Sea is about 30º higher than the average on the seabed. Measurements and drillings in the volcano pipe have shown that the volcano is still glowing.
How did the Dutch volcano originate?
Volcanism, like the volcano in the Netherlands, probably arose during the formation of mountains around the Jurassic period. Microplates in Turkey and Iran slowly moved north and collided with the Eurasian continent, creating shock waves in the continent. The result of this collision and shock waves is said to have created volcanism in the Netherlands and presumably also in the Alps.
Typical features of a stratovolcano are:
- The volcano is made up of different layers of solidified lava, alternated with rock (layering),
- Lava from a stratovolcano cools down quickly, keeping the lava close to the volcano,
- The symmetry,
- A stratovolcano is cone-shaped, steep and high,
- An eruption and an eruption of a stratovolcano is very explosive,
- Stratovolcanoes are dangerous, the longer an eruption, the more deadly the next eruption will be,
- An eruption of a stratovolcano is accompanied by the release of ash, sulfur, gases and stones,
- Mudslides are life-threatening that flow down the slope after an eruption of a stratovolcano.
Characteristic dead volcano
The Dutch volcano is now a dead volcano, with the most important characteristic:
A dead volcano has had no eruptions and eruptions for many thousands and sometimes even millions of years. The South Wall Volcano is a dead volcano that has not erupted for millions of years.
The Dutch volcano is a stratovolcano, famous stratovolcanoes include:
Mount Vesuvius (Pompei, Italy),
The Fuji (Japan),
- The El Arenal (Costa Rica).
Discovery South Wal volcano
How was the Dutch volcano discovered? The Zuidwal volcano was discovered in 1970 during a search for gas fields and gas bubbles in the Wadden Sea by the French oil company Elf Petroland. The oil company came across volcanic rock during the drilling. Moreover, the temperature at the bottom of the Wadden Sea close to the volcanic rock found was too warm than normal.
Zuidwal gas supplier
When the Dutch volcano became less active and eventually became a dead stratovolcano, the geological processes around the volcano were completed in such a way that the volcano in the Netherlands is now our gas supplier. Over the many millions of years, the volcano has managed to break the gas fields, push the many gas bubbles and gas fields upwards, so that we now have access to gas in the Wadden Sea.
Sail over the Dutch volcano
Everyone who goes by boat from Harlingen to the Wadden island of Vlieland sails over a unique natural phenomenon in the Netherlands: over the Zuidwal volcano.
Unique natural phenomenon in the Netherlands
The Netherlands is a very special country, but the fact that the Netherlands has a real Stratovolcano in its possession will surprise many. The Dutch volcano is a very rare natural phenomenon and a relatively unknown one!
