Quake it off: earth moves for Swift at Edinburgh shows

Thousands of fans at Taylor Swift's concerts in Scotland have caused earthquake readings kilometres away from the concert venue in Edinburgh, the British Geological Survey says.

Dressed in glittery, colourful outfits depicting different musical eras of the American pop star's discography, more than 70,000 fans, or "Swifties", flocked to see the singer-songwriter for her Eras Tour shows at Murrayfield stadium at the weekend.

Their dancing led to seismic activity being recorded at the earthquake monitoring stations 6km from the venue, the British Geological Survey (BGS) said in a statement on Thursday.

Each of the three evenings followed a similar pattern, with the songs Ready For It?, Cruel Summer and Champagne Problems resulting in the most significant seismic activity each night, the BGS said.

Previous performances in Seattle and Los Angeles registered similar seismic activity, with Swift's Seattle gig generating activity equivalent to a 2.3 magnitude earthquake.

Swift's tour is the world's highest-grossing concert tour.
