During Game 5 of the American League Division Series at T-Mobile Park in Seattle, the crowd support was so intense that it felt like the ground was shaking, according to Seattle Mariners’ Leo Rivas. This sensation was not far from the truth, as scientists from the Pacific Northwest Seismic Network were measuring seismic energy inside the stadium during the game. The device, nicknamed “Richter Rizzs,” captured bursts of ground movement after key plays, providing real-time data on the shaking levels during the Mariners’ victory over Detroit.
