Scientists Will Track Fan-Generated Earthquakes at Seattle Stadium During the World Cup

Seattle’s fan-generated seismic history is genuinely impressive. The phenomenon entered the public consciousness in 2011 when Seahawks running back Marshawn Lynch broke multiple tackles on a 67-yard touchdown run, generating enough crowd energy to register on local seismographs in what became known as the Beast Quake. That record stood for years until Taylor Swift’s Eras Tour came to Seattle, where dancing fans produced even greater seismic activity and temporarily claimed the title. Seattle Mariners fans have also contributed to the city’s tremor history, with the PNSN tracking significant ground shaking during the team’s 15th-inning walk-off win in Game 5 of the ALDS.

The World Cup project has a scientific purpose beyond the novelty. Because natural earthquakes are unpredictable while crowd enthusiasm at a sold-out World Cup match is essentially guaranteed, the tournament provides an ideal opportunity to test equipment and educate the public about how seismic instruments work and what they measure. Washington is one of the most seismically active states in the country, sitting atop the Cascadia Subduction Zone, and the PNSN sees value in using a high-profile public event to build awareness around how ground motion is recorded and interpreted.

Researchers will also be watching to see whether fans from the competing nations can out-shake Seattle’s own legendary crowd energy over the course of the tournament.
