Taylor Swift fans in Edinburgh danced so fervently at the singer's Eras Tour last weekend that they created seismic activity in the earth. On Friday, the British Geological Survey's monitoring stations detected activity caused by the more than 70,000-person crowd at Murrayfield Stadium, per The Hollywood Reporter. The organization shared that the most tremulous songs were Swift's "Shake It Off," "Cruel Summer," and ". . . Ready For It?"
The Edinburgh stay marked the first of Swift's 17 shows in the U.K., which The Hollywood Reporter reported is estimated to generate approximately $1.2 billion for the country's economy.
This wasn't the first time the pop star's concerts have caused something of a "Swift Quake." In March, Swifties at SoFi Stadium in Inglewood, California, caused earthquake-like activity, according to a study conducted by researchers at Caltech and UCLA. Last summer, a geology professor from Western Washington University determined that Swift's two-night stay at Seattle's Lumen Field led to seismic activity equivalent to a 2.3 magnitude earthquake.
