AceShowbiz - Taylor Swift's "Eras Tour" concerts in Edinburgh, Scotland, have literally shaken the city. The British Geological Survey (BGS) revealed that each of the concerts at Murrayfield Stadium recorded seismic activity, with Friday's show being the most energetic, at 23.4 nanometres (nm).

The activity was detected up to 6 kilometers (3.7 miles) away from the venue, although the BGS emphasized that the vibrations were unlikely to have been felt by anyone outside the immediate vicinity.

According to the BGS, the seismic activity was primarily caused by fans dancing in time to the music, reaching its peak during "Ready For It?", which transmitted approximately 80kW of power (equivalent to 10-16 car batteries).

Notably, this is not the first time Swift's tour has caused seismic activity. Last July, her concerts in Seattle, Washington, triggered activity equivalent to a 2.3 magnitude earthquake.

The Edinburgh shows marked the first of 17 dates in the U.K. for the "Eras Tour", which is projected to boost the country's economy by £997 million ($1.2 billion). The tour will conclude with a record-breaking eight nights at London's Wembley Stadium.

The seismic activity generated by Swift's fans exceeds that of rival artists such as Beyonce Knowles and Bruce Springsteen. However, it falls short of the record set by Harry Styles' fans last year.

The BGS also acknowledged that the effects of the seismic activity were limited to approximately 500 meters from the stadium.
