Mexico fans’ World Cup celebrations trigger measurable seismic waves

Mexico’s World Cup victory over Ecuador on October 17, 2026, sent more than a million fans into Mexico City’s streets, where their synchronized jumping generated seismic waves strong enough to register on local seismographs. The match, played at Azteca Stadium, ended 2-1 in favor of Mexico, with goals from Raúl Jiménez in the 34th minute and Julián Quiñones in the 89th securing the win. Post-match, crowds surged into the city center, where their collective motion—reminiscent of a stadium ‘siesmito’ tradition—created vibrations detected by the SASSLA seismic network.
