Taylor Swift's Seattle concert caused the ground to shake like a small earthquake

Taylor Swift fans are shaking the ground while they're shaking it off at her The Eras Tour concerts.

A seismologist recently discovered that fans attending Swift's recent concert in Seattle on July 22 and 23 danced so hard that, combined with the sound system, they caused seismic activity that could potentially be compared to a 2.3 magnitude earthquake.

Jackie Caplan-Auerbach, a seismologist and geology professor at Western Washington University, tracked the seismic activity from the concert and discovered the movement caused by the Swifties broke the previous record of movement at Lumen Field.
