Abstract : A set of charts is presented that relate earthquake magnitude and distance from source to peak horizontal acceleration, velocity, and duration for hard and soft sites. The charts are in two groups: one for shallow plate boundary earthquakes with focal depths < or = 19 km; another for subduction zone eqarthquakes with focal depths < or = 20 km. The motions that are obtainable from these charts are for use where dynamic analyses are contemplated and cyclic loading is required that approximates the effect of earthquakes as they would be felt in the free field at an engineering site. Keywords: Earthquake ground motions; Plate boundary motions; Subductive zone motions.
