Seismic liquefaction probability for Canadian offshore regions
Seismically induced liquefaction is a potential hazard to petroleum developments in Canadian offshore regions. This paper addresses the hazard to eastern Canada's continental margin and the Beaufort Sea. To indicate the probability of seismically induced liquefaction, maps have been produced th...

Seismically induced liquefaction is a potential hazard to petroleum developments in Canadian offshore regions. This paper addresses the hazard to eastern Canada's continental margin and the Beaufort Sea. To indicate the probability of seismically induced liquefaction, maps have been produced that contour the minimum value of soil resistant (N 1 ) required in order that the probability be less than 0.001/a. Expected acceleration levels for this probability level are also provided. For many areas, liquefaction is a greater hazard to offshore structures than that directly attributable to vibratory ground shaking. Key words: seismic hazards, liquefaction, offshore structures, Beaufort Sea, continental shelf, probability, Canadian offshore, ground motion, soil stability. |
