The experts say the biggest event was caused by all the jumping and dancing that followed the touchdown and 2-point conversion as Seattle rallied near the end of regulation.
The University of Washington's Steve Malone calls it a "dance quake" generated by bouncing fans.
Malone says that dance quake was the biggest seismic signal associated with a Seahawks game -- even bigger than the 2011 "beast quake" that followed a Marshawn Lynch touchdown run and originally drew the attention of earthquake trackers.
Other earthshaking events Sunday were Seattle's fake field goal touchdown and the winning touchdown in overtime.
