To provide pga (peak ground acceleration) site ground motion information throughout the study area from a simulated Cascadia Subduction Zone M 9.0 earthquake. Used in building and infrastructure damage models, and as an input into earthquake-induced ground failure model.
From DOGAMI OFR O-18-02.
Peak ground acceleration (pga) is the maximum ground acceleration that is estimated to occur at a location on the soil surface for a simulated earthquake. It is quantified as a proportion of standard acceleration due to gravity (or g). |
