The 'Eras Tour' show in California was classified as a 'microearthquake' and these 5 songs were the loudest.

A study on "The Eras Tour" stop was deemed a seismic event as researchers identified the five loudest moments.

A study published in Seismological Research Letters by Gabrielle Tepp of Caltech's research team revealed that a recent stop on Taylor Swift's "Eras Tour" caused monumental waves.

The research team installed powerful motion sensors at SoFi Stadium in Los Angeles, California, in preparation for the August 5, 2023, concert.

As reported by SWNS, the seismic signature and strength of each song's tremor would be detected by the sensors.

The team analyzed seismic data with the help of nearby networks and found that the strongest activity occurred during Swift's performance of "Shake it Off" in 2014.

According to a study, the 70,000 fans at SoFi Stadium generated a seismic wave with a 0.851 magnitude due to their dancing and jumping movements, as reported by SWNS.

According to SWNS, Tepp stated that the strongest tremor, based on maximum shaking, was equivalent to a magnitude -2 earthquake.

Last year, Southern California experienced 50 microearthquakes, according to a study.

The Eras Tour" featured other high-energy songs such as "You Belong With Me," "Love Story," "Cruel Summer," and "22.

Researchers compared the intensity of the concert to a recent Metallica concert, which also took place at SoFi Stadium.

Tepp stated that the harmonic signals at Swift's three-and-a-half-hour show did not match those recorded earlier.

Tepp explained that headbands are popular among metal fans, which means they are not necessarily bouncing.

She added, "Perhaps, the ways they move do not produce as strong a signal."

The seismic study revealed that Swift's songs maintain a consistent beat range during both recorded and live performances, which may have influenced the study results.

While Swift's show is largely choreographed, Metallica does not have choreography, which could affect tremor signals.

In this case, the earthquake was not the first instance caused by the pop star's fans.

Taylor Swift will return to the stage for her European leg of "The Eras Tour" in May 2024 in Paris.

The seismic activity at the July 22 and 23 tour stops in Seattle, Washington, was similar to a 2.3 magnitude earthquake, as reported by Jackie Caplan-Auerbach, a seismologist and geology professor at Western Washington University.

In May 2024, Taylor Swift will perform on stage in Paris, France as part of her European leg of "The Eras Tour."
