Two-point conversion generated biggest Seahawks quake

Earthquake experts with the Pacific Northwest Seismic Network have analyzed the CenturyLink Field shaking during the Seahawks’ win over the Packers in Sunday’s NFC title game. The experts say the biggest event was caused by all the jumping and dancing that followed the touchdown and two-point conversion as Seattle rallied at the end of regulation time. 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 TD run. – AP
