What is Anisotropic seismic ground responses identified from the Hualien vertical array about?

This paper presents the results of ground response analyses using the freefield motions of six earthquakes recorded at the site of the Hualien Large Scale Seismic Test. From the phase spectra of transfer functions between the ground motions recorded at the surface and various depths, the predominant frequencies of soil layers are identified and used to estimate the shear wave velocities of soil layers. Results show that the soils at the Hualien LSST site are anisotropic, such that the earthquake responses exhibit different characteristics in two horizontal principal directions.
