A seismologist recorded seismic activity equivalent of a 2.3 magnitude earthquake during Swift’s concert in Seattle.

“If I overlay them on top of each other, they’re nearly identical.”

“Beast Quake” was beaten out by “Swift Quake” by a 0.3 magnitude.

“The primary difference is the duration of shaking,” Caplan-Auerbach said.

“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 tour spans all of her musical eras and albums, including her most recent tenth studio albumMidnights.
