Vulcano in Eifel near NRW: the magma chamber fills - is there a catastrophe? | waz.de

Berlin
A magma chamber is filled under the Laacher lake in the Eifel. This is indicated by earthquakes. The volcano still seems active.

In Eifel it was the last big 13000 years ago vulcanic eruption, Today he only remembers it Lake Laacher, which has become a popular destination. Below the lake is a magma chamber, which now fills up again, as scientists have discovered.

But the volcano of the Eifel has long since disappeared not the only volcanic area in GermanyThere are also volcanoes in other regions that have been sleeping for thousands of years. when Volcano under the Laacher See shows the correct activity with the filling of the magma chamber. Which is timely with an outbreak at disaster arrives, but thinks they are unlikely.

Vulcano in the Eifel becomes more active

The lake basin was created after the ceiling of the magma chamber lowered. the Laacher See volcano Although he has remained silent for a long time, he still sends signs of life.

Exams of state seismic services indicate that the magma chamber is full. They have responded to a series of weaker earthquakes in recent history. Recently there was a similar series of earthquakes in November 2016 in the Swabian Hegau.

As a team of researchers in the journal "Geophysical Journal International", he has one since 2013 four series of weak earthquakes recorded bales, called "Deep Low Frequency" (DLF) at a depth of 45 km.

These would not be caused by the change of the Earth plates, but by themselves liquid magma on the surrounding rocks in the crust land vorbeidränge. The earthquakes have not been warned on the surface.

No sign of imminent volcanic eruption

"Under active volcanoesFor example, in Iceland, Japan or Kamchatka, such earthquakes can be observed on a regular basis, "explains Torsten Dahm, Head of the Earthquake and Volcanic Physics section at the Potsdam Geo Research Center in a statement.
However, these are not signs of an imminent eruption.

"The rise of the magma in the surface crust of the earth usually goes on swarms of high frequency earthquakes associated. This activity has not yet been observed in Eastern Eifel, "says Joachim Ritter of the Karlsruhe Institute of Geophysical Institute of Technology. Furthermore, it should raise the earth's surface, which also did not happen.

Bonn professor of geology Ulrich Schreiber considers an epidemic unlikely in the near future, but says "Express" that he will "return" one hundred percent.

Researchers call for a re-evaluation of volcanic risk

According to the current state of science, it should be a last eruption of the Eifel volcano about 13,000 years ago 30,000 years he took until the current eruption came. It is not possible to go back to when the DLF earthquakes started in Eifel. However, the researchers consider a start before 2013 to be plausible.

The measurement system has been significantly expanded by the findings. Scientists are now demanding intensify surveillance, Also the volcanic danger of the Eifel must be re-evaluated.

Volcanic eruptions in several countries

the Lake Laacher it is about 24 kilometers from Koblenz and about 40 kilometers from Bonn Street. A map shows the exact location:

Where are the volcanoes in Germany?

There are active volcanoes in Germany no more For this, some sleep. The eruption of the volcano in the Eifel about 13,000 years ago was the last major eruption. All the other volcanoes remained silent for a while.

These are the volcanic areas in Germany:

  • Jute sinks around Kassel
  • Vogelsberg in Hesse
  • Rhon
  • seven mountains
  • Westerwald
  • Eifel
  • Erzgebirge
  • Kaiserstuhl near Freiburg im Breisgau
  • Hegau in Baden-Württemberg
  • Alb Swabian
  • Northeast Bavaria
  • Franconian forest and
  • Fichtelgebirge
  • Upper northern Palatinate

How many volcanoes are there in the world?

In total there are around 1500 active volcanoes worldwide. Furthermore, there are countless unknowns that are found under water. How many are those that are difficult to say exactly.

Where are the volcanoes that are still active today?

There are many volcanoes in the world that are particularly active. Some of them are even in Europe. A selection of the most active volcanoes in the world:

  • Hekla in Iceland
  • Mount St. Helens in the United States
  • Hunga He "apai" in Tonga
  • Popocatépetl in Mexico
  • Colima in Mexico
  • Merapi in Indonesia
  • Stromboli and Etna in Italy
  • Piton de la Fournaise on the island of Reunion in France

Where are the most volcanoes?

Volcanoes are often where the tectonic plates meet. In these areas there are many cracks and fissures in the Erdkruse. Rising from the earth magma there form volcanoes.

What is the most dangerous volcano in the world?

To the most dangerous volcanoes in the world you can count different. Above all, the super volcanoes are particularly dangerous. Unlike many others, they are not even recognizable by a mountain like a volcano. For example, the Yellowstone or flegrei fields near Naples in Italy.

With an eruption of these two volcanoes the consequences for the whole world would be difficult to estimate. (Bekoe / cho)
