New Zealand: Earth moves for Foo Fighters fans

The Foo Fighters' latest concert in New Zealand rocked. Literally.

The gig in Western Springs on Tuesday caused vibrations "similar to a volcanic tremor", geologists said. "The strong correlation in time with the Foo Fighters concert and the fact it was only recorded on the two stations close to Western Springs assured us it was man-made," said GeoNet, which monitors geological hazards in the country. "The ground was shaking three times per second in a nice rhythmic motion."

The geologists said the tremors – most pronounced at 8.20pm when the band first took to the stage – were most likely caused by the weight of 50,000 fans dancing to the music.
