Flashback to her mistakes, her rebounds, her earthquakes. In another case of life imitating art (this time, the art being lyrics to Taylor Swift‘s 2017 Reputation track “Dress”), Swifties at the Eras Tour in Seattle last weekend danced so hard, they generated enough seismic activity to rival a low-grade earthquake. The discovery was found by Jackie Caplan-Auerbach, a geology professor at Western Washington University, who measured the “Swift-quake” at Lumen Field to be equivalent to a 2.3 on the magnitude scale.
The findings called back to another incident at Lumen Field in 2011, when fans watching a Seattle Seahawks game went wild over an impressive touchdown by running back Marshawn “Beast Mode” Lynch. The rumblings from the game showed up on the same local seismometer as the activity from the Eras show, according to Caplan-Auerbach.
“The shaking was twice as strong as ‘Beast Quake,’” she added. “It absolutely doubled it.”
Comparing activity from the Saturday (July 22) show with the Sunday (July 23) show, Caplan-Auerbach shared that there wasn’t one crowd of Swifties that was discernibly more raucous than the other. Both groups danced equally enthusiastically, the only main difference being that the second show started about half an hour later than the first due to delays.
It wasn’t just scientists who noticed the record-breaking movement at the stadium, by the way. Even Swift was impressed by all the energy she greeted with, afterward writing on Instagram, “Thank you for everything. All the cheering, screaming, jumping, dancing, singing at the top of your lungs.”
The conclusion of the Seattle shows means that Swift has just one more state to visit on the U.S. leg of the Eras Tour, which she’ll wrap up with two performances at Levi’s Stadium in Santa Clara, Calif., followed by six concerts at SoFi Stadium in Inglewood, Calif. From there, she’ll embark on months of international shows, traveling through Latin America, Europe, Asia and Australia with support from Sabrina Carpenter and Paramore.
And even regardless of seismic activity, fans at the rest of those Eras Tour venues have a lot to live up to following Seattle. While onstage Sunday night, Swift doubled down on a diary entry she recalled writing during 2018’s Reputation Tour: “Seattle, Washington is the best crowd I have ever played for.”
