Beast Quake (Taylor's Version): Swift's "Eras" tour concerts cause seismic activity in Seattle

Swifties have taken their love for pop superstar Taylor Swift to another level — literally shaking the Earth beneath them with their passion.

At two "Eras" tour concerts at Seattle's Lumen Field on July 22 and 23, Swift and her fans managed to make enough noise and movement to actually rock the ground beneath them for four straight hours, causing a "Swift Quake," according to Jackie Caplan-Auerbach, a geology professor at Western Washington University.

While the seismic event caused by the concert was not an actual earthquake, its occurrence is still the subject of great curiosity amongst experts and pop fans alike, Caplan-Auerbach told CBS News.
