Under normal circumstances, a statement about a band “rocking so hard it started an earthquake” would be dismissed as hyperbole.
In this case, however, it appears that a band truly did cause a genuine seismic event – two of them, actually.
According to by volcanic watchdog site GeoNet, the Foo Fighters rocked an audience of 50,000 in Auckland, New Zealand, so hard that it actually registered twice on seismographs as activity “similar to a volcanic tremor.”
GeoNet’s blog claims that two separate monitoring stations picked up “semi-continuous harmonic signals” beginning shortly after the band’s set commenced. The vibrations lulled in between songs and peaked in the middle of songs, when the Foo Fighters were apparently shaking the earth up to three times per second – consistent with a volcanic tremor.
“The first vibrations were recorded around 7:30 p.m., part way through the Tenacious D set,” one scientist wrote, “but the biggest shakes started at 8:20 p.m. when the Foo Fighters took the stage, and then it all went quiet at 11 p.m. when the gig ended.”
“You can almost pick out individual songs on the signal!” he added.
The cause of the shaking, the scientist hypothesized, was the movement and weight of the 50,000 dancing fans, the equivalent of approximately 5,000 tons of moving mass. For the record, this is not the first time the sensors picked up a man-made tremor. GeoNet also once registered seismic events from the Rugby World Cup finals.
The Scorpions might have rocked you like a hurricane, but apparently only the Foo Fighters can rock you like an earthquake.
