SEATTLE (AP) Earthquake trackers are adding instruments at CenturyLink Field in Seattle to record expected vibrations from jumping and stomping Seahawks fans.
University of Washington scientists with the Pacific Northwest Seismic Network were setting up Thursday in preparation for Saturday's playoff game.
Their attention was initially drawn to the stadium in 2011 when a Marshawn Lynch touchdown run against New Orleans was recorded on a Seattle seismometer.
Scientists are using the stadium monitors to look for problems they might encounter with a real earthquake. They're also testing technology that could provide an early warning of underground shaking.
