Abstract

Abstract: It is shown that the synthetic earthquake displacements over a large area (100×100 m 2 ) on ground surface can be described well by a plane surface undergoing translations and rotations, with only minor departures of displacements from those of a plane flat surface. Rotational motions are largest on deep soil sites over sediments and smallest for motions on the geological basement rocks. Highlights: Synthetic earthquake motions of a large surface area 100×100 m 2 . Role of site conditions on motion of a large surface area. Dependence of rocking and torsional excitations on site conditions. Coherency of synthetic body and surface waves in parallel layers.
