The scientists believe the small earthquake during a Marshawn Lynch touchdown was likely greater than Lynch's famous "beast quake" touchdown run three years ago, which also came against New Orleans during a playoff game.
John Vidale of the Pacific Northwest Seismic Network (PNSN) at the University of Washington told The Seattle Times they will know for sure in a few days.
PNSN posted graphs during the game through its Twitter and Facebook accounts.
Fans jumped and stomped their way to magnitude 1 or 2 earthquake in 2011 during Lynch's rambling, tackle-breaking "beast quake" run.
