Foo Fighters Concert Causes Earthquake-Level Tremors
When the Foo Fighters proudly “rocked” Auckland, New Zealand, during their performance there on Tuesday, they did so more literally than they could have known.
An entry from GeoNet, a New Zealand-based earthquake blog, indicated that two of Auckland’s seismic stations within a two-kilometer proximity to Western Springs Stadium, where the Foo Fighters were performing, detected a strong low frequency of geological tremors that persisted during the exact same window of time as their show and rose and fell with the peaks and troughs of their performance. Though only the two nearest seismic stations picked up on the frequency, GeoNet states it was “similar to volcanic tremor that is recorded at places like Mt Ruapehu and White Island.”
The first signs of the earthquake-like tremors appeared during Tenacious D’s opening set around 7:30 p.m. The shakes increased tremendously in power at 8:20 p.m. when Dave Grohl and company took the stage and promptly stopped when the show ended at 11 p.m., with lulls in the signal between songs and an increase in frequency during the songs’ loudest parts.
GeoNet explained that the 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.”
This earth-shaking show marks the Foo Fighters’ last concert until March. In the meantime, the group has been nominated for six Grammys for their latest album Wasting Light and its smash hit single “Walk.”
