How a Shaking Stadium Is Helping Scientists Track Earthquakes

vinces99 writes Researchers are installing three seismometers in Seattle's CenturyLink stadium to monitor shaking from Seahawks fans during Saturday's NFL playoff game. The new, faster data transmission will show crowd motion on the website before a touchdown shows up on the 10-second delayed TV broadcast. Researchers dub these "Early Earthquake Rowdiness Warnings." A guaranteed shaking and intense public interest gives the seismologists a unique opportunity to test new technology that gives seconds to minutes warning of a real earthquake.

      The vibrations don't travel instantly through the surrounding geology, so if you know instantly when a quake happens at the epicenter, you can still give meaningful warning to people in outlying areas. Also (as a non-geologist), I suppose there's probably patterns that show up before the biggest part of the quake...if you start feeling what seems like a 3.0, but your phone can alarm with "This is going to get up to an 8.0 in twenty seconds", it could save your life.

      Depends on how far you are away from the epicentre. Earthquakes travel at approximately the speed of sound. I've had notification of an earthquake before I felt it before -- it's a somewhat spooky experience.

      P-waves are like large scale sound waves, and travel about (or a little slower) than speed of sound in the ground, which is several times faster than the speed of sound in air most people would think of. S-waves and a few other more esoteric ones travel slower, about half the speed, and can result in two easy distinquish parts of an earthquake if you are far enough from the epicenter.

Four years after the Christchurch earthquake, ours is an abandoned concrete tomb that looks fine but is apparently damaged beyond use. It was under-insured. The insurance companies will only pay out to repair it, other engineers say that's impossible.

      If the stadium owners thought insurance was the way to go, they were highly mistaken and this proves the point.

      Insurance is the biggest scam out there. It doesn't matter what the insurance policy says, insurance companies will do everything in their power not to pay out anything or at best, a token amount.

      Witness what happened when Katrina (a hurricane for those not in the know) hit Louisiana. The insurance companies tried to claim storm surge damage wasn't covered even though the houses were damaged by winds.

      Even worse, the people relied on their insurance agent who told them they didn't need flood insurance. Further, they lost their case.

      Pick any insurance you want and the same applies. You pay and pay and pay, then when you need coverage, you pay some more before the insurance companies hand over a pittance.

      Hopefully the stadium owner goes after the insurance company and forces them to do what they were paid to do. If not, get your money back for breach of contract.

    I work a block from Centurylink Field. A contractor is currently running a piledriver in the Centurylink parking lot for the construction of a new hotel and will be driving over 100 piles through mid-March. The piledriver shakes my office building; Monday night football does not. The pilediver vibrations would provide a more realistic representation of seisimic activity in the area, not to mention an abundance of samples. This is simply a chance for the University of Washington (with its huge Husky Football progam) to team up with pro football on a publicity stunt under the ruse of science.

      That's precisely why they're studying the stadium rather than the pile driver. It requires more sensitivity in order to make the readings. Plus, it's unlikely that this source of study is going to go away before the construction on that building does.

      Not to mention that the stadium is a somewhat random occurence. We know that the fans can effect the equipment, but when they do it is somewhat unpredictable as is the extent to which they effect it. Seems like a decent thing to be studying.
