Ground acceleration 意味
http://www.efehr.org/earthquake-hazard/hazard-map/ WebGround shaking. The second primary earthquake hazard, ground shaking, is the result of rapid ground acceleration. Ground shaking can vary over an area as a result of factors such as topography, bedrock type and the location and orientation of the fault rupture. These all affect the way the seismic waves travel through the ground.
