SEATTLE — Marshawn Lynch's 67-yard touchdown run that clinched Seattle's upset of New Orleans in the first round of the NFL playoffs may be remembered for more than the half-dozen or so broken tackles.

It shook Qwest Field and the ground around the stadium – literally.

John Vidale, director of the Pacific Northwest Seismic Network, says that a seismic monitoring station about 100 yards west of the stadium registered seismic activity during Lynch's fourth-quarter run that clinched Seattle's 41-36 victory.

Vidale says he was inspired to look at the seismic graphs after watching a video posted on the Internet from the upper deck of the stadium and noticed the shaking as Lynch completed his TD run.

Vidale says the shaking lasted about 30 seconds and then faded off for another minute.
