SPATIAL VARIABILITY OF EARTHQUAKE GROUND MOTION
Abstract
The spatial variability of ground motion is the phenomenon of an earthquake, though people are usually not aware of it. Measurements from closely-located seismographs have shown that ground motion during an earthquake, measured at different locations, can be different and can affect large structure such as bridges, pipelines, dams, tunnels etc., with the consecutive seismic response of these structures. The spatial variability of ground motion can be mainly attributed to the wave passage effect, loss of coherence and different local soil conditions.
