果冻影院 team records ground shaking at Taylor Swift concerts

1 July 2024

果冻影院 geophysicists installed nine seismometers around Wembley Park ahead of Taylor Swift鈥檚 first Eras concerts in London and found that the opening night performance of 鈥楲ove Story鈥 produced the strongest ground tremors.

The instruments recorded ground seismic waves generated by fans dancing within and outside Wembley Stadium over three nights, from 21st to 23rd June.

The opening night recorded the greatest levels of ground motion of the three dates with Earth movement up to a maximum of 0.03 mm (the size of a very fine hair). 鈥楲ove Story鈥 produced the strongest ground shaking, equivalent to an earthquake of magnitude around 0.8, followed closely by 鈥楽hake It Off鈥.

The team, who were invited to install the seismometers by Wembley Park, were led by geophysicists Professor Ana Ferreira and Dr Stephen Hicks (both 果冻影院 Earth Sciences), with instruments shared by UK-based manufacturer G眉ralp Systems Ltd and University of Oxford鈥檚 Dr Paula Koelemeijer.

Professor Ferreira and her team detect and study a wide range of phenomena using seismic data. In a previous project, the team placed 50 seismometers on the floor of the Atlantic Ocean, detecting whale songs as well as the 2022 Tonga earthquake on the other side of the planet.

Professor Ferreira said: 鈥淭aylor Swift fans were clearly having the time of their lives in Wembley Park during Taylor鈥檚 first London concerts.

鈥淲ith our instruments we were able to 鈥榣isten鈥 to the Earth's heartbeat which was certainly beating fast during songs such as 鈥楲ove Story鈥 which produced energy in the ground equivalent to an earthquake of magnitude around 0.8.

鈥淭his is a great testimony of how even a so-called small magnitude event is actually 鈥榖ig鈥, being generated by such a huge and enthusiastic dancing crowd.鈥澨

Dr Stephen Hicks said: 鈥淎mazingly, each of Taylor鈥檚 concerts over the three consecutive days at Wembley produce near-identical seismic signals, which is quite a unique phenomenon in nature. This gives us quite a novel opportunity to probe the subsurface environment beneath urban areas and to compare between different cities around the world where Taylor has performed.鈥澨

Paul Burke, a PhD student in palaeontology at 果冻影院 Earth Sciences, said: 鈥淏eing a Swiftie since I was 13, I never thought my job as a researcher at 果冻影院 and Taylor Swift would collide together. Taylor brings so much joy to so many people and there鈥檚 a feeling you get from going to her concert that you cannot replicate.

鈥淲e got to use science to measure seismic activity during her concerts at Wembley, showing the fun applications science has and the importance of it.

鈥淗opefully this experiment leads to the public being more aware of all the great science we do at 果冻影院 and all the fun things we can do with it.鈥
