Which World Cup goals shook - or didn't shake - Seattle Stadium
Seattle's World Cup matches didn't produce any "Beast Quake" moments, but tens of thousands of fans certainly felt the earth move under their feet as they cheered - or booed - during the six games in Seattle Stadium.
Among the top five shakiest moments of the nearly two dozen goals, three came from when the U.S. scored in its two matches against Australia and Belgium - no surprise, given the number of American fans in the crowd. The other two are from the Egypt-Iran game, a high-octane match with a goal from Iran that was negated after a video review for offside.
That's according to the Pacific Northwest Seismic Network, which has seven seismometers around the stadium that measure how much the building shakes as fans jump, cheer and clap at the same time.
The two goals that generated the most rumbling are when U.S. defender Alex Freeman scored the team's second goal against Australia, and when Iran's Shoja Khalilzadeh hit a goal that would have sent Iran to the knockout stage.
Seismologists detected patterns in the ground motion to see where different countries' fans were sitting, based on which seismometers detected shaking, said Zoe Krauss, a PNSN postdoctoral researcher. In the Iran-Egypt match, two seismometers detected a stronger signal near the Iran fans reacting to the third goal. When it was overturned, a third seismometer near the Egypt fan section detected the most rumbling.
"We often didn't really know where fan sections were sitting until the first goal, then it's obvious," Krauss said. "It's cool to see."
They also saw distinct signals from specific chants and dances. The reaction after a Bosnia and Herzegovina goal showed a rhythmic pattern with a huge signal, Krauss recalled. They realized the fans were jumping up and down in unison while they danced to a song.
The two top goals are among the top 10 shakiest moments recorded at Lumen Field, er, Seattle Stadium, on par with Seattle Seahawks safety Kam Chancellor's interception return in 2015 against the Carolina Panthers, according to the PNSN. But they are only about 70% of "Beast Quake, the 2011 iconic play when Marshawn Lynch ran for a 67-yard touchdown against the New Orleans Saints. The roaring energy registered on a nearby seismometer as the equivalent of a magnitude 1 or 2 quake.
"'Beast Quake' is our standard to beat," PNSN director Harold Tobin said Monday afternoon, before the match. "Let's watch tonight."
The match instead set an opposite record: Belgium's four goals generated the quietest reaction of any throughout the tournament. The final three goals barely registered at all, according to Krauss - and any Team USA fan in or near the stadium.
Tobin cautioned that "sportsquakes" aren't comparable to real earthquakes. A recent 3.8 earthquake near Oak Harbor, for example, registered about the same as the stadium shaking did to the seismometers.
"It's a reminder that real earthquakes are a whole, real deal that is very different," he said. "We are having fun pointing ('sportsquakes') out, but it's not the same."
