Introduction
A technique for estimating and characterizing the spatial variation of
earthquake ground motion based on recordings obtained from dense
seismograph arrays is outlined. Critical steps in the estimation
procedure are emphasized. Erroneous estimates may be obtained is special
care is not taken in the estimation. The proposed estimation technique
is validated by using it on simulated accelerogram whose spatial
variability is known. Finally, the technique is used to estimate the
parameters of a random field model of earthquake ground motion, for two
far-field events recorded by the SMART-1 seismograph array in Lotung,
Taiwan.
