Taylor Swift's Swift-Quake Explained: How Eras Tour Attendees Surpass 2011 Beast Quake

Taylor Swift's fans who attended her Eras Tour in Seattle literally shook it off and caused a 2.3 magnitude Swift-Quake.

Swift has been visiting states over the past months as part of her Eras Tour's US leg before the singer jets to other continents. Most recently, she marked her show at Seattle's Lumen Field, during which her fans caused seismic activity that broke the previously-set record in the area.

What Is Taylor Swift's "Swift-Quake"?

CNN quoted seismologist Jackie Caplan-Auerbach's findings that led to the creation of the newly-coined term "Swift Quakes," following Swift's shows at Lumen Field in Seattle on July 22 and 23.

Caplan-Auerbach, who is also a geology professor at Western Washington University, said the two-day event caused seismic activity "equivalent to a 2.3 magnitude earthquake," during the fans' dance activity at the venue. The beat, speakers, music, and fans' movement were part of the 10 hours of data she collected before reaching the findings.

"I grabbed the data from both nights of the concert and quickly noticed they were clearly the same pattern of signals," she explained. "If I overlay them on top of each other, they're nearly identical."

The Swift-Quake followed a similar occurrence in 2011 when Seattle Seahawk fans reacted to Marshawn "Beast Mode" Lynch's touchdown when the team had the NFC Wild Card game against the New Orleans Saints. The event, called "Beast Quake," was immediately beaten by "Swift-Quake" by recording double its amount.

Talking about the quakes' difference, the professor told CNN that the cheering after Lynch's touchdown only lasted for a few seconds. Meanwhile, Swift's record was made due to its long-hour "energy" given by her fans.

Swift will have one more state to perform before wrapping up her Eras Tour's US leg, visiting venues in California ahead of her international shows in Latin America, Europe, Asia, and Australia.

Taylor Swift Scores Another Win

Aside from setting records with her Eras Tour, Swift also savored a big win when Teresa La Dart, who accused her of stealing "Lover" book, dropped the case, which the singer's lawyers called baseless.

The little-known author from Mississippi argued that Swift's book copied several creative elements from her 2010 book, also titled "Lover." The motion filed in Tennessee federal court Thursday said the author permanently dropped the case.

Swift's "Lover" book was released in four different versions, and all of which included her personal diary entries and photos she personally handpicked.
