Taylor Swift - She makes the earth tremble in Switzerland
US-Popstar Taylor Swift (34) is currently entertaining her European fans. On Tuesday evening (9th of July), the singer performed at Zurich's Letzigrund Stadium in front of approximately 50,000 people, causing numerous jumping and dancing fans. This was noticeable in the ground as well. The Swiss Seismic Service described the show in a statement as an "event with seismic footprint."
"When many people move rhythmically at the same time, this energy is transferred as a harmonic vibration into the ground and can be measured by nearby seismometers," it is explained. The ground motions caused by the concertgoers were measured at eight stations of the seismic network up to a distance of six kilometers from the Letzigrund Stadium. However, they disappeared "in the background noise" afterwards.
Tribunes amplify ground movements
According to the Seismic Service, other large concerts or soccer games have also left their traces in seismic data in the past. How clearly these can be read depends on various factors, such as the proximity to a seismometer or the type of soil. The ground movements are amplified, "when a building such as a tribune is excited in its resonant frequency by the people in it," the statement reads. Whether Taylor Swift excited more or less than other bands or soccer games remains unclear from the data.
"The Eras Tour" by Taylor Swift is a "journey through the musical phases" of her career, so songs from all the successful musician's studio albums can be heard. Swift will also come to Germany with her show. She will perform at Veltins-Arena in Gelsenkirchen on the 17th, 18th, and 19th of July. There will be two performances in Hamburg (Volksparkstadion) on the 23rd and 24th of July. Afterwards, she will be seen in Munich's Olympiastadion on the 27th and 28th of July.
During Taylor Swift's concert at Zurich's Letzigrund Stadium, the vibrations caused by thousands of dancing fans were so intense that they were registered as an "event with seismic footprint" by the Swiss Seismic Service. As the concert went on, the ground motions were even amplified when the energy from the jumping and moving fans resonated with the tribunes.
