scope:
This standard provides criteria and guidelines for conducting geological, seismological, geophysical, and geotechnical investigations needed to provide information to support the following:
(1) seismic source characterization input to a probabilistic seismic hazard analysis (PSHA);
(2) evaluation of tectonic permanent ground deformation (PGD) hazard using probabilistic fault displacement hazard analysis (PFDHA) for surface-faulting sources and probabilistic tectonic deformation hazard analysis (PTDHA) for blind fault sources;
(3) site response analysis input to PSHAs;
(4) nontectonic, earthquake-induced ground failure hazard;
(5) foundation stability.
