Cologne Bay earthquake area

from Wikipedia, the free encyclopedia
Earthquake zones DIN 4149

The Cologne Bay is part of the Rhenish earthquake zone, which extends from the Basel earthquake area to the Benelux countries .

Emergence

The Cologne Bay is not located on the border between two continental plates , where earthquakes otherwise often occur, e.g. B. in Japan .

The quakes in the Cologne Bay are caused by the fact that the African plate south of Italy is pressing against the Eurasian plate . This pressure is forwarded. This creates tensile and compressive stresses in Central Europe , which discharge as earthquakes in weak areas such as the Cologne Bay. In the course of these earthquakes, the Cologne Bay slowly sinks.

meaning

The earthquakes in the Cologne Bay have been recorded and published since 1975. Several times a month there are small earthquakes in the Cologne Bay , which are usually not felt, for example in November 2005: Mersch (Jülich) and Eschweiler (November 2, 0.7 to 1.2), Alsdorf- Blumrath (11 November, strength 0.7), Erp (November 13, strength 1.0), Bergheim- Niederaußem (November 16, strength 0.9), Roermond (November 19, strength 1.2), Bad Ems ( November 21, magnitude 2.2), Mersch (November 22, magnitude 0.8).

Earthquakes in the past

Early earthquakes have been recorded since 880 (Mainz) and 1080 (Cologne).
