The Taylor Swift fever shows no signs of stopping. The singer continues her The Eras Tour after releasing her new album, The Tortured Poets Department, and is currently performing concerts across various locations in the United Kingdom.

Recently, the news highlighted the impact of her concerts in Edinburgh, thanks to her devoted fans known as Swifties. Over three shows, a record-breaking 220,000 people gathered, making it the highest attendance for a single artist in a Scottish venue.

The enthusiasm and energy of the American singer’s fans were so intense that they caused seismic activity. This phenomenon occurred specifically during her hits “Shake It Off” and “Cruel Summer.”

According to the British Geological Survey (BGS), seismic activity was recorded six kilometres away from the Murrayfield Stadium. The fans’ jumping caused the ground to move up to 23.4 nanometres (nm) during the most energetic of the three concerts. The other two concerts recorded movements of 22.8 nm and 23.3 nm on Saturday and Sunday, respectively.

BGS further analysed that during the song “Ready For It?”, the crowd’s heart rates peaked at 160 beats per minute, and the fans generated about 80 kilowatts of energy, equivalent to around 6,000 car batteries.

“It’s incredible that we could remotely measure the reaction of thousands of concert-goers through our data,” stated Callum Harrison, a seismologist at BGS, in a press release.

Seattle Swifties Cause Earthquake

During Taylor Swift’s performances in Seattle in July 2023, two earthquakes with a magnitude of 2.3 on the Richter scale were recorded on the 22nd and 23rd of July, attributed to her concerts at the Lumen Field stadium. Approximately 70,000 people attended each night.

These measurements were captured by the Pacific Northwest Seismic Network, as reported by local media, attributing the phenomenon to a combination of the fans’ fervour and the powerful sound equipment used.

Seismologists noted that the seismic activity was consistently recorded on both days at the same times, with peaks around 7:30 PM and 9:30 PM, suggesting that the tremors occurred during specific segments of the concert.
