Abstract EN
Spatial variation of earthquake ground motion is an important phenomenon that cannot be ignored in the design and safety of strategic structures.
However, almost all the procedures for the evaluation of variation assumed that the random field is homogeneous in space.
It is obvious that reality does not fully conform to the assumption.
How to investigate the inhomogeneous feature of ground motion in space is a challenge for researcher.
A body-fitted grid-coordinates-based method is proposed to estimate and describe the local spatial variations for the earthquake ground motion; it need not to make the assumption that the random field of earthquake is homogeneous in space.
An analysis of spatial variability of seismic motion in smart-1 array monitored in Lotung, Taiwan demonstrates this methodology.
