We know the Foo Fighters rock...now there is seismographic proof to corroborate our beliefs. At a show in New Zealand, the Foos along with the 50,000+ in attendance caused the Earth to tremor and stuff.
Take it away scientific people:
The east coast was largely unprepared for yesterday's 5.9 magnitude tremor. So it should come as no surprise that when the ground started shaking, it was time to GTFO (if you don't know internet lingo, google that one).
