They REALLY rocked: Foo Fighters' New Zealand gig causes volcanic tremors a MILE AWAY



The Foo Fighters have been dubbed the hardest rocking band in the world after their concert caused volcanic tremors a mile away.

Scientists from the GeoNet network recorded the ground literally rocking to the gig at the Western Springs Stadium in New Zealand on Tuesday night.

Fifty thousand fans watched front man Dave Grohl and his band mates perform their three-hour set, oblivious that it and their dancing was causing the volcanic tremor, similar to 5,000 tonnes of earth moving.

Rocking out: Scientists said the 50,000 fans dancing at the Foo Fighters gig on Tuesday most likely caused the seismic activity in Western Springs, New Zealand

The first vibrations were recorded around 7.30pm, part way through the set of support band Tenacious D, fronted by actor Jack Black.



But the biggest shakes came after the Foo Fighters took to the stage at about 8.20pm.

According to the Auckland GeoNet blog the vibrations from the gig emitted a 'strong low signal.

'The ground was shaking three times per second in a nice rhythmic motion,' the blog recorded.

The recordings were taken at the two monitoring stations located 1.5km (0.9m) and 2km (1.2m) from the concert.

'The signal is similar to volcanic tremor that is recorded at places like Mt Ruapehu and White Island,' the blog stated.

'However 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 of man-made origin.

'There are lulls in the signal between the songs and peaks in signal intensity during the songs.'

The scientists wrote: 'The cause of the shaking is most likely the weight of the 50,000 fans dancing, as 50,000 fans is equal to around 5,000 tonnes of mass moving on the ground.

'This set up a nice harmonic vibration in the ground which was recorded in our nearby borehole seismometers.'

Foos fanatic George Beatty, who was at the gig, said he wasn't surprised.

'It was amazing, they rocked for three hours,' said mosher George. 'The stadium shook as everyone got going, I bet the locals had a few smashed plates in their homes tonight.'

Local resident Alan Murphy, 65, wasn't impressed by the concert. 'It was a horrific noise,' said the retired banker. 'It was like hell, I was sure the roof tiles were going to start falling off at some point.'
