CalTech and UCLA researchers found that Swifties’ dancing and jumping during her Eras Tour concert at SoFi Stadium in Los Angeles caused seismic activity.

Caltech and UCLA researchers found that 70,000 Swifties’ jumping and dancing caused seismic disturbаnce at SoFi Stadium in August 2023 during her career-spanning concert.

Last year’s “Swift quake” at the Grammy winner’s July tour stop at Seattle’s Lumen Field was the “equivalent of a 2.3 magnitude earthquake”.

On Wednesday, the researchers published “Shake to the Beаt: Exploring the Seismic Signals and Stadium Response of Concerts and Music Fans.” The academic research reported “distinct harmonic tremors.” from crowd motions, not music.

The Los Angeles Times said that the researchers set up motion sensors around five-and-a-half miles from SoFi Stadium on Swift’s fifth night of her six-night stint.

Spectrograms showed that “Shake It Off” had the highest local magnitude of 0.851 and “Love Story” had a substantial amplitude.

The scientists even examined “concert tremors” from Beyoncé, Metallica, and Morgan Wallen’s massive gigs at the same arena to determine how big “Swift quakes” are.

Caltech and UCLA’s study followed seismologist Jackie Caplan-Auerbach’s July investigation on seismic activity from her Eras Tour event at Seattle’s Lumen Field’s record-breаking crowd.

On tour since spring 2023, Swift’s Eras Tour has broken attendance records and became the highest-grossing music tour ever.

The hitmaker played a few North American performances at the close of last year after touring North America for much of spring and summer.

Swift returned to her three-and-a-half-hour act in 2024 with concerts in Japan, Australia, and Singapore. She’ll shortly tour Europe.

On April 19, the “Cruel Summer” singer will release her 11th studio album, The Tortured Poets Department. She will resume the Eras Tour in late May. She’ll play a few North American gigs in the fall after a summer of European and U.K. appearances.

Disney+ has premiered the singer-songwriter’s live concert film. Last October, Sam Welch’s documentary premiered in theaters. The full-length version, which included the show’s entire setlist, was released on streaming several months later.

The film’s premiere weekend box office and streaming numbers were the highest ever for a concert film. Taylor Swift | The Eras Tour (Taylor’s Version), Disney+’s exclusive, became the platform’s most-watched music film three days following its release.
