Seismologist Jackie Caplan-Auerbach has reported that Taylor Swift's concerts in Seattle, USA, caused seismic activity equivalent to a 2.3 magnitude earthquake, BBC reports.
The data was recorded during Swift's sold-out Eras tour performances at Lumen Field on 22 and 23 July. The seismic activity was attributed to the enthusiastic response of Swift's fans or possibly the powerful sound system used during the shows.
The magnitude of the seismic activity generated by Swift's concerts surpassed the previous record set in Seattle known as the "Beast Quake" in 2011. The "Beast Quake" occurred when American football fans celebrated Marshawn Lynch's touchdown for the Seattle Seahawks during a game against the New Orleans Saints.
Dr. Caplan-Auerbach, a geology professor at Western Washington University, explained that the difference in magnitude between the NFL game and Swift's concerts was only 0.3. However, the shaking caused by the concerts was twice as strong as the "Beast Quake" and effectively doubled the seismic impact.
The concerts in Seattle drew a massive crowd of 144,000 fans over two nights, making it a memorable experience for Swift and her enthusiastic audience. After the shows, Swift took to Instagram to express her gratitude, calling it one of her favorite weekends ever and thanking the fans for their enthusiastic support.
This is not the first time that music concerts have caused seismic activity. Notably, during a 2011 Foo Fighters concert in New Zealand, similar effects were observed due to the energy and excitement of the audience. Swift's concerts in Seattle mark the conclusion of the US leg of her Eras tour, which is her first tour in five years.
Earlier this month Taylor Swift also saw her four albums simultaneously enter the U.S. Top 10 list, which makes her the first woman and only the third artist overall to achieve this height.
