- Abstract
- This report describes seismic data recorded during Kingdome Seismic Hazards Investigation of Puget Sound (SHIPS), March 24-28, 2000. The primary goal of Kingdome SHIPS was to measure the spatial variations in site response throughout Seattle using the implosion of the Seattle Kingdome, a concrete domed stadium, as a seismic source. A secondary goal of our work was to refine knowledge of the location of the Seattle fault. During Kingdome SHIPS we deployed 228 temporary seismic stations (landbased Texans, RefTeks, and K2s) on a hexagonal grid with a receiver spacing of 1 km. We used this array to record the seismic waves generated by the implosion of the Kingdome, with the intention of making a movie of the ground motions produced by the demolition in Seattle. The Kingdome was demolished on March 26th (JD 086) to make room for a new professional football stadium. Earlier that morning, we recorded our four 150-lb shots at the corners of the receiver array to offsets up to 20 km.
