Taylor Swift's tour stop in Seattle caused a 2.3 magnitude 'Swift Quake,' according to a seismologist
- Taylor Swift recently brought the Eras Tour to Seattle's Lumen Field.
- A seismologist said the concerts caused seismic activity equivalent of a 2.3 magnitude earthquake.
Taylor Swift's latest tour stop in Seattle was so lively that it registered as an earthquake, according to a local expert.
When Swift brought the Eras Tour to Lumen Field on July 22 and 23, two nights of dancing and ground-shaking pop music caused seismic activity equivalent of a 2.3 magnitude earthquake, seismologist Jackie Caplan-Auerbach told CNN.
"I grabbed the data from both nights of the concert and quickly noticed they were clearly the same pattern of signals," she said. "If I overlay them on top of each other, they're nearly identical."
The so-called "Swift Quakes" are reminiscent of the 2011 "Beast Quake," which occurred when Seattle Seahawks fans celebrated a 67-yard touchdown by running back Marshawn Lynch, whose nickname is "Beast Mode."
But according to Caplan-Auerbach, the Swifties "doubled" the power of the NFL fans.
"The shaking was twice as strong as 'Beast Quake,'" she told CNN.
"The primary difference is the duration of shaking," Caplan-Auerbach explained. "Cheering after a touchdown lasts for a couple seconds, but eventually it dies down. It's much more random than a concert. For Taylor Swift, I collected about 10 hours of data where rhythm controlled the behavior. The music, the speakers, the beat. All that energy can drive into the ground and shake it."
The Eras Tour celebrates Swift's 17-year career in the music industry with a set list that draws songs from every corner of her discography, concluding with her 10th studio album "Midnights." It's currently on track to bring in $1.4 billion, according to Forbes.
The Seattle stop broke the attendance record for Lumen Field, previously set by U2 in 2011. The US leg will wrap on August 9 in Los Angeles.
