A note on the motion of a large area on ground surface during passage of synthetic strong motion waves

摘要

It is shown that the synthetic earthquake displacements over a large area (100 x 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. (c) 2015 Elsevier Ltd. All rights reserved.
