3 November 2021–Seismic hazard analyses may use ergodic ground motion models—a sort of “average” based on global data about ground motion—or non-ergodic models, which incorporate more local and regional data on seismic source and nearby geologic structures. Having that site-specific analysis can make a big difference, as consulting seismologist Gilead … Continue Reading »
