During a Seattle football game on January 8, 2011, the Pacific Northwest Seismic Network (PNSN) recorded what was dubbed a "Beast Quake", for Marshawn "Beast Mode" Lynch, a player whose performance on one running play excited the Qwest Field stadium crowd enough for the resultant shaking to be recorded on PNSN instruments. In 2014 and 2015 additional sensors were added in and around the stadium. Motivations for the experiment included conducting a quick-reaction exercise for the seismometer network team to install sensors and interpret results, and to test the ability to handle increased web traffic from interested visitors from the general public. Shaking was detected at the stadium after a 90-yard touchdown run during a January 10, 2015 playoff game, dubbed a "Kam Quake" for the player making the run, Kam Chancellor. The PNSN scientists say that the biggest event of all was the "Dance Quake", which was caused by all the jumping and dancing that followed Marshawn Lynch's touchdown and 2-point conversion during 2014–15 NFC Championship Game on January 18, 2015. Another earthquake was recorded on November 10, 2019, during the MLS Cup final between the Sounders and Toronto FC.
