Mexico Fans' Celebrations After World Cup Win Produced Seismic Signal

Mexico defeated Ecuador in the round of 32 of the 2026 World Cup after goals by Julián Quiñones and Raúl Jiménez. The fans' celebrations produced vibrations that registered as a significant artificial signal on a Raspberry Shake seismograph near Mexico City Stadium, Mexico’s Digital Platform for Early Warning and Comprehensive Risk Management reported.

SASSLA stated on its social media accounts that the outburst of euphoria and mass cheering produced vibrations in the local area.

A comparable signal appeared after Hirving Lozano’s winning goal for Mexico against Germany at the 2018 World Cup in Russia, when Mexico’s Institute of Geological and Atmospheric Research linked the reading to mass jumping by spectators. Geophysicists recorded a similar quake in Bergen, Norway, during Norway’s knockout-round goals last week.

A Taylor Swift concert at SoFi Stadium in Los Angeles in 2024 also generated long-duration, low-frequency signals with harmonic peaks between 1 and 10 Hz.

Arturo Iglesias, a researcher at the Institute of Geophysics at the National Autonomous University of Mexico, said human activity can generate movements recorded by seismographs yet does not constitute geological phenomena measurable by seismic magnitudes or capable of altering the subsurface.

“Even if a person jumps next to a sensor, it’s detected, but it’s not an earthquake. An earthquake caused by the scattered activity of fans is a joke,” Iglesias stated.

Iglesias noted that seismic systems detect micro-movements from both natural and human sources, with readings affected by station location, terrain, and activity intensity. Experts said improved analysis of such signals could aid seismic interferometry techniques that study subsurface structure without controlled explosions or natural quakes.
