60,000 Fans Caused a Small Earthquake Because of One Famous Rock Song

Last week, on May 7, during a concert at the Virginia Polytechnic Institute and State University's Lane Stadium, the synchronized jumping of 60,000 concert goers was enough to register activity at the Virginia Tech Seismological Observatory. The song? That would be the 1991 hit "Enter Sandman," from rock legends Metallica.

"The seismic activity, now named the 'Metallica Quake,' was too minor to register on the Richter scale or be assigned a rating," according to a report from Ultimate Guitar.
