Swifties Set Off 2.3 Magnitude ‘Swift Quake’

Taylor Swift fans are reportedly causing some seismic activity.

According to seismologist Jackie Caplan-Auerbach, the newly-coined "Swift Quakes" occurred on July 22 and 23 at Swift's Eras Tour dates at Seattle's Lumen Field — which saw record attendance on Saturday — People reported.

Caplan-Auerbach stated that the Swifties' dance activity caused seismic activity "equivalent of a 2.3 magnitude earthquake," per the outlet.

The Western Washington University geology professor noted the occurrences while moderating a Pacific Northwest earthquake group on Facebook.

"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."

Caplan-Auerbach pointed out that similar activity occurred in the seaport city with 2011's "Beast Quake," when Seattle Seahawk fans went wild over Marshawn "Beast Mode" Lynch's incredible touchdown during the NFC Wild Card game against the New Orleans Saints.

However, the Swifties have the NFL fans beat. "The shaking was twice as strong as 'Beast Quake.' It absolutely doubled it."

"The primary difference is the duration of shaking," the professor told CNN. "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."
