Los Angeles: Rock band Foo Fighters` recent concert in New Zealand, attended by 50,000 fans, has reportedly caused earthquake level geological tremors.
Data from the country`s GeoNet blog claims that two seismic stations outside the Western Springs stadium in Auckland - 1.5 and 2 kilometers from the locale respectively - detected a strong low frequency of tremors at the time of the show on December 13.
The tremors correlated specifically with the highs and lows of the performance. The levels recorded were consistent with that of volcanic activity, said The Hollywood Reporter.
"The first vibrations were recorded around 7:30pm, part way through the Tenacious D set, but the biggest shakes started at 8:20pm when the Foo Fighters took the stage, and then it all went quiet at 11pm when the gig ended," Geonet states.
"The concert vibrations were recorded as a semi continuous harmonic signal with a peak osculation of 3Hz, i.e. the ground was shaking 3 times per second in a nice rhythmic motion. There are lulls in the signal between the songs and peaks in signal intensity during the songs."
Foo Fighters is up for six Grammy Awards during the February 12 ceremony, including album of the year for `Wasting Light`, as well as best rock performance and best rock song
