WebAug 6, 2024 · Peak Ground Acceleration (PGA) 0.2 second Spectral Acceleration (SA) 1.0 second Spectral Acceleration (SA) Units for all 3 maps are %g (percent of gravity). This can also be expressed in decimal form, example 10%g = 0.1g. The ground motion values apply to ground motion expected for future individual earthquakes. WebYou can have accelerations of 1 g for a M6.0 quake, and less than that for a magnitude of 9.0. It is intensity, not magnitude, that is related to accelerations. Accelerations are related … treino f1 hoje ao vivo
