Port of Everett <br /> 2.The liquefaction resistance of a soil is based on its density and fines Everett, Washington <br /> content. We used the results of the standard penetration testing to LIQUEFACTION ANALYSES, BORING 13-113 <br /> estimate the density,and the results of selected laboratory tests to estimate IBC DESIGN GROUND MOTION <br /> the fines content. <br /> 3. We considered a seismic event with a 200-year return period for the M =6.5, PGA=0.32 <br /> liquefaction analysis.The moment magnitude is 6.5 and the peak ground January 2014 21-1-21761-003 <br /> acceleration is 0.32g.See main text for more information. <br /> SHANNON &WILSON, INC.
