Thousands of Taylor Swift fans created a seismic sensation by cheering and dancing at her three Edinburgh concerts last weekend.
Fans took her song “Shake It Off” literally, generating seismic activity detectable from 6km (3.73 miles) away.
The biggest commotion occurred during “Cruel Summer,” “Ready For It?” and “Champagne Problems,” with Friday night’s 73,000-strong crowd making the most noise.

This was the first of Swift’s 17 UK dates, culminating in a record-breaking eight-night run at London’s Wembley Stadium.
Her 152-date stadium tour is projected to make over $2bn (£1.56bn), potentially the most lucrative concert tour in history. Over the three Murrayfield shows, 200,000 fans witnessed her career-spanning, three-hour performance.
The Friday concert saw fans make the ground move 23.4 nanometres (nm), compared to 22.8nm and 23.3nm on Saturday and Sunday.
Seismic activity peaked at 160bpm during “Ready For It?” generating approximately 80kW of power. Even a four-minute applause for “Champagne Problems” caused noticeable tremors. Similar events were registered during her Seattle and Los Angeles shows, with the Seattle gig equivalent to a 2.3 magnitude earthquake.
The British Geological Survey (BGS), the UK’s national earthquake monitoring agency, confirmed that their sensitive detectors picked up the activity miles away. Callum Harrison, a BGS seismologist, remarked on the thrill of measuring this unique seismic activity, noting Scotland’s enthusiastic audiences.
The movement, recorded at two monitoring stations, the furthest 6km away at Heriot Watt University, was unlikely to be felt beyond the concert vicinity.
