Effective peak ground acceleration
WebMay 15, 2024 · A method is described for the prediction of site-specific surface ground motion due to induced earthquakes occurring in predictable and well-defined source zones. The method is based on empirical Green’s functions (EGFs), determined using micro-earthquakes at sites where seismicity is being induced (e.g., hydraulic fracturing and … WebPeak ground acceleration can be expressed in g (the acceleration due to Earth's gravity, equivalent to g-force) as either a decimal or percentage; in m/s2 (1 g = 9.81 m/s2); or in Gal, where 1 Gal is equal to 0.01 m/s² (1 g = 981 Gal). The ground type can significantly influence ground acceleration, so PGA values can display extreme ...
