A pop star shocks up the underground: When Taylor Swift enacts in Hamburg today and tomorrow sunset, fans can pursue it unusually: via Swift Quakes. A livestream shares the seismic ripples that are made by the earthquakes at the live show – initiated by the dancing of the active Swifties in the arena and the bass of the theme. What’s unique: Hamburg is residence to one of the highest-resolution seismic fleece optic grids in the world.
When the earth trembles, there is not consistently a geological cause after it. Man-made circumstances such as construction work, outbreaks, or the remote testing of a bomb also cause seismic tremors. They can be caught by seismometers, but even by the even more exposed fiber optic threads in our contact networks: if the fiber optic cords are tested and squeezed by seismic tremors, this warps the optical signs running via them and thus offers the waves.
The sharpness of the fiber optic counting networks is even acceptable to capture very unique man-made locks: the pulses generated by football fans bouncing up when a purpose is scored or the dancing of active “Swifties” at a Taylor Swift show, as US geophysicists have found.

German geophysicists will now catch these “Swift quakes” – and promote them live during the two Taylor Swift shows in Hamburg. “We already understand that we can catch the pulses from shows in Hamburg’s Volksparkstadion because we include already done so, for instance at a Metallica show,” describes the group directed by Céline Hadziioannou from the University of Hamburg.
Their big benefit: The “Science City” in Hamburg-Bahrenfeld is house to “WAVE”. One of the thickest and most acute measure networks of all. “The Science City has a dimensions web with unique solutions,” says Hadziioannou. Especially, the seismic and geo-acoustic WAVE network consists of a capacity of around 19 kilometers of thread optic cables. Which equals to around 19,000 sensors.
These permit ground motion data to be registered over large spaces at a density never reached before. The accelerator structures of the X-ray laser European XFEL and German Electron Synchrotron (DESY). Discovered in this section are also used as counting stations.
Livestream from 6:00 p.m.
“We like to use Taylor Swift’s shows to reveal how the ‘WAVE’ network functions. And what information is likely with it,” says Oliver Gerberding from the University of Hamburg. To accomplish this, the students are recording the pulses that happen on July 23 and 24 during the Swift shows, which take place about two kilometers out in Hamburg’s Volksparkstadion and are posting them on Twitch for live stream.
The live streams of the “Swift Quakes” begin at 6 p.m. on both show days and are free. It can be considered without registration. Those who didn’t get tickets can at least watch the quakes that happen during the pop star’s concerts.
