Taylor Swift’s fans literally shook the ground during two of her concerts in Seattle.

According to CNN, seismologist Jackie Caplan-Auerbach says seismic activity equivalent to a 2.3 magnitude earthquake while dancing at her “Eras” tour stops at Lumen Field pn July 22nd and 23rd.

The “Swift Quake” was being compared to the 2011 “Beast Quake,” when Seattle Seahawks fans erupted in celebration after a touchdown by Marshawn “Beast Mode” Lynch.

Ms Caplan-Auerbach, who works as a geology professor at Western Washington University, saw the comparison in an earthquake group she moderates on Facebook and immediately got to work.

She says she pulled the data from both nights of the concert and quickly noticed they were clearly the same pattern of signals.

And for those who want to know, the “Swift Quake” was stronger than the “Beast Quake”.
