Yesterday, the sports world was gripped by Barcelona’s stunning 6-1 victory over Paris Saint-Germain (PSG) in the round-of-16 of the UEFA Champions League. Going into the game, Barcelona needed to outscore PSG by five goals to move on to the quarterfinals. Until the finals of the Champions League, games are played at each team’s home venue and total goals are combined. Three weeks ago in Paris, PSG beat Barcelona 4-0. Then, last night in epic fashion, Barcelona scored three goals in the final seven minutes, including the last one in the 5th minute of stoppage to send them through 6-5 on aggregate.
Due to the raucous environment of fans jumping up and down in excitement at Camp Nou (Barcelona’s home venue), a seismic station 500 meters from the stadium picked up ground motion throughout the game. The image below shows readings from the Instituto de Ciencias de la Tierra Jaume Almera (ICTJA) throughout the game, with markers at each goal. Based on the readings, one can see that when Barcelona scored their sixth and final goal, ground motion was double what it had been at any time prior. Additionally, it was much more prolonged, most likely due to celebrations and the impact of the result. It should be pointed out that “fanquakes” have a much different seismic signal than real earthquakes and can thus be easily distinguished.
Readings such as these are similar to those recorded by the Pacific Northwest Seismic Network at Seattle Seahawks football games, which we blogged about two months ago. To read that blog, click here. What all of these readings show is that regardless of the type of football being played, people at sporting events can create their own little earthquakes.
