Taylor Swift concert causes earthquake

Taylor Swift’s three sold-out concerts in Edinburgh, Scotland, triggered tremors about 4 miles (6.5 kilometers) from the venue, according to the British Geological Survey (BGS).

Edinburgh’s Murrayfield Stadium saw record crowds as the American superstar performed for about 3.5 hours each night from June 7-9, CNN reported.

BGS said “all three nights produced a similar seismic pattern,” with the performance and dancing to Ready For It?, Cruel Summer and Champagne Problems generating the most tremors.

BGS added that the crowds at each show produced their own unique readings, but the data appeared to show that Friday night (June 7) was the most intense.

“The tremors were detected by scientific equipment so sensitive that even the smallest seismic activity could be detected many kilometres away, so the seismic tremors generated by the concert would have been unlikely to have been felt by anyone other than those in the immediate vicinity,” BGS said.

According to Scottish Rugby, which owns the stadium, nearly 73,000 fans attended the first night. The next two nights both broke records on June 7. It was also the largest stadium concert in Scottish history. Last summer, Harry Styles’s show attracted around 65,000 fans.

The Eras Tour, which saw Swift perform in 22 countries over 152 dates, is set to become the highest-grossing tour of all time.

The Eras Tour is estimated to have brought in around £1 billion ($1.27 billion) to the UK economy, according to research from Barclays Bank.

“These sell-out shows have brought huge and wide-ranging benefits to the city. Not only did they contribute an estimated £77 million ($98 million) to the local economy, but they also provided a further boost to our global reputation as a great place to live, work and visit,” Edinburgh City Council leader Cammy Day wrote in a post on the city’s official website on June 12.

“I would also like to pay tribute to the hundreds of thousands of Swifties whose behaviour has been, by all accounts, exemplary,” Day wrote.

“BGS is the national agency responsible for recording earthquakes to inform government, the public, industry and regulators, and to enable a better understanding of earthquake risk and planning for future events,” said Callum Harrison, a seismologist at BGS, on the organisation’s website. “It was incredible to be able to measure the reactions of thousands of remote concertgoers using our data. The opportunity to explore seismic activity generated by a different type of phenomenon was exciting.”
