The USGSs has upgraded the earthquake detection devices on the Marquam Bridge in Portland.   Jim Smith, with the USGS, says they were originally installed during the seismic retrofit in 1995. When a large quake hits the devices will record how the bridge is affected. The data will be used to determine how the Marquam Bridge survives the quake and also how to design future bridges that are more earthquake resistant.
