US soccer fans create seismic activity during World Cup match in Seattle

During the FIFA World Cup match between the U.S. men’s soccer team and Australia on June 19, seismic activity was recorded at Seattle's Lumen Field. The Pacific Northwest Seismic Network (PNSN) documented fan response to both U.S. goals and a VAR decision. The first goal generated a peak of 3.3 mm/s², while the second registered 3.0 mm/s², reflecting the crowd's emotional intensity during pivotal moments. This phenomenon is similar to past high-energy events in Seattle but is not actual seismic activity. Seismic data will continue to be collected during the six World Cup matches held in Seattle.
