Seismologist reports Taylor Swift's Seattle concerts caused seismic activity akin to a 2.3 magnitude earthquake!
Seismic data from Swift's packed Eras tour shows recorded activity at Lumen Field on 22 and 23 July.
Seismologist Jackie Caplan-Auerbach said the activity was caused by Swift's fans or the sound system.
The shows beat the previous record in Seattle, known as the city's "Beast Quake" in 2011.
That was generated by American football fans celebrating Marshawn Lynch's touchdown for the Seattle Seahawks during a game against the New Orleans Saints.
Dr. Caplan-Auerbach, a geology professor at Western Washington University, told CNN that Swift's recent concerts produced shaking twice as strong as an NFL game, with just a 0.3 difference.
The data from both concert nights showed identical patterns of signals when overlaid, indicating a strong similarity between the two performances.
Swift expressed her gratitude for the enthusiastic crowd in Seattle, calling it one of her favorite weekends ever, with cheers, screams, jumps, dances, and singing at the top of their lungs.
Swift's Seattle concerts came towards the end of the US leg of the Eras tour - her first tour in five years.
Music concerts have been known to cause seismic activity before, for example during a 2011 Foo Fighters concert in New Zealand.
