"The Matterhorn looks like an immovable, massive mountain that has towered over Zermatt in the landscape for thousands of years. A study now shows that this impression is deceptive. An international team of researchers has proven that the Matterhorn is constantly in slight motion: the peak swings back and forth by a few nanometers to micrometers in just over two seconds, stimulated by seismic waves in the ground. These are generated by natural sources such as the tides, the surf, the wind, earthquakes or human activity."
