Taylor Swift’s fans at her gigs in Scotland were so “Ready For It” that they set off earthquake monitors by dancing so hard, according to the British Geological Survey (BGS).
Seismic activity was recorded up to six kilometres away during the three gigs last Friday, Saturday and Sunday at Edinburgh's Murrayfield stadium, with some of the 34-year-old global super star’s biggest songs causing spikes in activity every night.
Data recorded by BGS found that the Friday night crowd were the most energetic with fans making the ground move a maximum of 23.4 nanometres (nm), compared to 22.8nm and 23.3nm on the Saturday and Sunday respectively.
While songs Shake It Off and Cruel Summer made the ground move, Ready For It? saw the seismic activity reach its peak at 160bpm.
To put it into perspective, the energetic Swifties created approximately 80kW of power during the song, equivalent to around 6,000 car batteries.
Detectors even shook during a four-minute long applause for Champagne Problems.
The movement was detected at two monitoring stations, and the furthest away of which was 6km away at the BGS office at Heriot Watt University.
“Clearly Scotland’s reputation for providing some of the most enthusiastic audiences remains intact,” BGS seismologist Callum Harrison said of the findings.
“It’s amazing that we’ve been able to measure the reaction of thousands of concert goers remotely through our data,” Mr Harrison added.
Swift's previous tour dates in Seattle and Los Angeles registered similar events, with her Seattle gig generating activity equivalent to a 2.3 magnitude earthquake.
The Anti-Hero hit-maker is set to continue her Eras tour in Liverpool on Thursday, then Cardiff and ending in London's Wembley Stadium for a record-breaking eight nights later this month and in August.
