    Seahawks Stadium Game Quakes?

    Yes indeed, during the Seahawks vs 49'ers game the PNSN installed siesmographs in the stadium as an expeiment in monitoring how human crowds affect ground motion.

    Here is the link to the Play by Play siesmological readout of that game. The lagest magnituge was calculated out to 1.2 Mag. Thats some rowdy fans!

    It looks like the pic is from the 'Hawks/Saints game.

    My first thought is how it compares to other stadiums and playoff games.

    I've heard for years about crowds and such producing measurable seismic activity.

    It's worth bearing in mind that the soil in that area is pretty much fill, over an area that was originally tidal. It's pretty much Jell-O.

    But GO HAWKS anyhow.

    Someone on my Facebook feed made a snarky comment about how the '49ers are scared of earthquakes. And I thought, "If they are, that's awfully sensible of them. Tell me why we aren't again?"

    Seahawks fans just assume that ground motion is a function of their normal discombobulated but non-threatening environment, whereas '49ers react viscerally and look for somewhere to escape.

    I love football jokes where both teams (that aren't *my* team) can look bad.

    Slightly off-topic, but before last week's game I found myself hoping for bad weather, like the week before, but then realized that the 49'ers until a couple of weeks ago played at Candlestick Park. It would have been an advantage for them.

    This reminds me of seeing the grandstands bouncing up and down under jumping fans at RFK Stadium when the Redskins ruled the NFL roost. I know it was a movable sheet metal section that could be moved around to reconfigure the stadium for baseball, but it added to the excitement when watching the game on TV. That section was directly across from the press box and usually was in sight in the background.
