GROUND MOTION CHARACTERISTICS OF CHRISTCHURCH CITY, NEW ZEALAND, OBTAINED BY MICROTEMOR MEASUREMENTS
|
抄録（英）：
Microtremor measurements were made in Christchurch city New Zealand. 24-hour observations were made at three specific sites where seismic observations had been carried out. Horizontal to vertical spectral ratios showed less time dependence for the successive 24 hours in comparison with Fourier spectra. Predominant periods and peak values were correlated with the ground motion characteristics obtained from the seismic data. Predominant periods and peak values obtained from the spectral ratio for moving observations varied with the surface geology such as volcanic rocks, dunes, peat swamps and lagoons demonstrating their applicability to the seismic microzonation.
