12.3.2 Site seismic hazard

A probabilistic seismic hazard analysis of the site was conducted (Moehle
et al. 2011). A total of fi ve hazard levels were included in the analysis. The
hazard levels were designated using SLE25, SLE43, DBE, MCE, and OVE
that correspond to return periods of 25, 43, 475, 2475 and 4975 years,
