Scientists have looked into a small ‘quake’ last year in Los Angeles while Taylor Swift was in the city for her Eras Tour.
Researchers believe Seattle and Los Angeles may have experienced their own Swift Quakes last summer because of her fans jumping up and down and dancing.
A team led by Gabrielle Tepp of Caltech believes fans jumping motions at the Eras Tour at SoFi Stadium, caused distinct harmonic tremors. They conclude it wasn’t the loud music or reverberations of the sound system that caused it.
They were able to identify the seismic signature of individual songs from Taylor Swift‘s setlist to determine the strength of a tremor in a particular record.

Researchers then compared it to other concerts that summer at the same stadium, including Beyonce and Metallica.
Following the Seattle Swift quake, the California Office of Emergency Services asked scientists to see if they could learn anything from it. Tepp’s team set up motion sensors at the stadium and have now analyzed the data.
Tepp said: “For earthquakes, most of the time they’re pretty sharp and easy to identify with waveforms, but when you have something like volcanoes where you have such a wide variety of signals, spectrograms can be really handy in helping to identify the different types of signals.”
The data found each song from Swift had a distinct tremor signal, with scientists identifying 43 out of the 45 songs played at the concert.
Her song Shake It Off had the largest local magnitude, but what makes it different from normal earthquakes is that it’s released over a few minutes and not in one sharp tremor.
