Something seismic happened at GARTH BROOKS' concert in Baton Rouge, Louisiana on Saturday. The crowd got so loud during his performance of "Callin' Baton Rouge" that it caused a small earthquake.
He was performing at Louisiana State University's Tiger Stadium and a seismograph on the campus recorded the quake around 9:30 P.M. The song is an unofficial anthem for LSU fans at football games, and they're nuts about it.
It's a massive stadium and those crowds have caused earthquakes during other sporting events. The 1988 upset of Auburn is known as the "Earthquake Game." But this may be the first time it happened during a musical event.
Here's another reason why the earth moved. There were 102,321 fans, which made it the second-largest stadium concert in North American history. 104,793 people attended George Strait's 2014 show at AT&T Stadium in Arlington, Texas.
