Taylor Swift's Ireland concert caused 'seismic event' due to huge crowds

Researchers have found that Taylor Swift triggered seismic activity during the three nights of her Eras Tour at Dublin’s Aviva Stadium recently, with activity from fans 'shaking it off' being tracked more than 100km away.

Researchers at the Dublin Institute for Advanced Studies (DIAS) found that during fan favourite song 'Shake It Off', seismic activity from the Dublin crowd could be identified as far away as Wexford, with the observed frequency (2.66Hz) matching with the song’s beats per minute (BPM) of 160.

Seismic activity is a vibration generated by an earthquake, explosion, or similar energetic source that travels within the Earth or along its surface.

21 seismometers, instruments which measure ground vibrations to track earthquakes, were placed outside the Aviva Stadium by DIAS researchers to measure seismic activity generated during the concerts for a purpose-made Eras Tour seismic study labelled the 'Swift Quake programme'.

The 50,000-strong Friday night crowd a Taylor Swift danced, cheered and stomped the loudest of the three gigs according to DIAS, with particular impact coming as fans danced to ‘Love Story’.

Eleanor Dunn, PhD candidate at DIAS and lead researcher on the 'Swift Quake programme', said her goal for the research was "to create a greater understanding of seismic activity".

"The engagement with fans has been great so far with lots of people sharing their concert videos with us. The videos help us to enhance our understanding of the seismic impact of each concert and the research data has revealed some fascinating insights into the energy generated by Swifties.

While the results of the distance travelled by the Swiftie-seismic activity are astonishing, Dunn stressed that it’s important to note "the movement generated by the concert was unlikely to have been felt by anyone other than those in the immediate vicinity".

While it may not have been felt, the distance was still a surpries to the lead researcher.

“Fans took Swift’s encouragement to ‘Shake It Off’ to a new level with it being detectable over 100km away in Wexford! It’s amazing that we’ve been able to measure the reaction of thousands of Swifties through our data," Dunn said.

"The opportunity to explore a seismic activity created by a different kind of phenomenon has been really interesting and shows how seismicity happens every day without us knowing. We’re still working on analysing data from the concert and we’d love if fans could continue to send us their videos from each night of the concert via our social media channels and website.”
