USGS-Provided Output
SS = 1.470 g SN15 = 1.470 g SoS = 0.980 g
Sl = 0.586 g Sh1z = 0.880 g SDI = 0.586 g
For information on how the SS and Si values above have been calculated from probabilistic (risk-targeted) and
deterministic ground motions in the direction of maximum horizontal response, please return to the application and
