Metallica fans bouncing in unison at the thrash heroes' recent show in Virginia, USA, caused a small earthquake recorded by local scientists.
Virginia Tech Seismological Observatory measured tremors, particularly during the band's performance of Enter Sandman at Virginia Polytechnic Institute and State University's Lane Stadium on Wednesday, 7 May.
Synchronised jumping by the 60,000 fans in attendance was responsible for the readings captured by the observatory.
Enter Sandman is played as a tradition at home games of the Virginia Tech Hokies (American) football team.
Virginia Tech Athletics wrote in a social media post: "Thanks for jumping with us, Metallica! Come back anytime."
Metallica are currently on a 21-date North American tour will run from April to June next year, with support at various stops coming from Pantera, Limp Bizkit, Suicidal Tendencies and Ice Nine Kills.
The dates are a continuation of Metallica’s M72 world tour, which started in 2023 after the release of the their latest album, 72 Seasons.
The tour continues the "No Repeat Weekends" model, where multiple stops will include two shows at the same venue, with no song getting played twice across the two nights.
