Abstract Short-period Love wave dispersion from the Kurile Islands earthquake (June 22, 1952; O = 21b 41m 53s; φ = 46° N; λ = 153°.5 E) can be explained with a two-layer crustal model in which the upper 2 km. of material has a shear-wave velocity of 2.31 km/sec. The second layer has a thickness of 4 km. and a shear-wave velocity of 3.71 to 3.86 km/sec. Shear-wave velocities of 4.50 to 4.52 km/sec. are used for the material immediately below the crust. This crustal model is compared with structures obtained from short-period Love wave dispersion across other Pacific paths and with results of refraction studies.

Cone Penetration Tests

A modified version of the spectral analysis of surface waves (SASW) equipment and analysis procedure has been developed to determine in situ shear-wave velocity variation with depth from the ground surface. A microcomputer has been programmed to acquire waveform data and perform the relevant spectral analyses that were previously done by signal analyzers. Experimental dispersion for Rayleigh waves is now obtainable at a site and inverted with a fast algorithm for dispersion computation. Matching experimental and theoretical dispersion curves has been automated in an optimization routine that does not require intermittent operator intervention or experience in dispersion computation. Shear-wave velocity profiles measured by this procedure are compared with results from independent seismic cone penetration tests for selected sites in western Canada. Key words : surface wave, dispersion, inversion, optimization, shear-wave velocity.
