When mega pop star Taylor Swift gave a series of concerts last August at the SoFi Stadium in Los Angeles, regional seismic network stations recorded unique harmonic vibrations known as “concert tremor.” A similar “Swift quake” had occurred the month before in Seattle, prompting scientists from the California Institute of Technology and UCLA to take a closer look at seismic data collected during Swift’s LA concert.
The researchers concluded that the vibrations were largely generated by crowd motion
