Taylor Swift's L.A. Fans Caused Earthquake During SoFi 'Eras' Concert

Taylor Swift can not only rock the house, she can rock the earth itself -- something proven by the fact that her fans caused a mini earthquake last year ... which is insane.

A study was conducted by Caltech and UCLA, which monitored just how much the ground was shaking during one of Taylor's concerts in 2023 -- specifically, one of her six L.A. shows at SoFi stadium ... and as it turns out, the Swifties that day made the needle move.

Seismologist Gabrielle Tepp -- who oversaw this study -- says data shows that her Aug. 5 "Eras" concert, which hosted upwards of 70,000 fans, registered notable seismic activity.

Tepp and co. monitored each song from her long set list with remote stations that were within 5.6 miles of the stadium and he says their records show that her performance of "Shake It Off" clocked in at the highest point through the night, with a peak magnitude of 0.851.

He notes that the seismic stations recording this were capturing the dancing and jumping going on from fans -- and the reverberations from the music itself isn't included in this. Tepp says her performance of "Love Story" that night also left a notable impression on the meter.

All in all, Tepp says the L.A. show movement caused tremors that equated to a magnitude-2 earthquake -- which is relatively small ... but still pretty impressive from the Taylor fan base!

Her Seattle fans reportedly caused similar waves earlier last summer as well ... earthquake levels.
