We all know that the Foo Fighters do their fair share of rocking, but did you know that their pure face-melting abilities can be measured on a seismograph from quite a distance away?
While on tour in Auckland, New Zealand, Dave Grohl and his cohorts inspired an audience of 50,000 to dance so hard that it registered as seismic activity by volcanic watchdog site GeoNet.
As described on the site's hilariously named blog Shaken Not Stirred, two separate monitoring stations picked up semi-continuous harmonic vibrations from up to two kilometers from the concert. The ground shook three times per second, which registered as a steady rhythmic motion -- at about the same level as a volcanic tremor. The graphed results (as seen below) show lulls in activity between shakes, which directly correlates to when the band was between songs. "You can almost pick out individual songs on the signal!" the excited geo-dudes wrote.
The same seismographs have picked up man-made tremors before, the last one coming from the Rugby World Cup finals. With enough power to shake the earth itself, the Foo Fighters are one step closer on their quest of world domination.
