Microtremor measurement by ground surface array have been done at two reclaimed site located in Tokyo Bay area. Phase velocity and traveling direction of microtremors are determined from the frequency-wavenumber spectrum analysis. In the frequency range of surface ground natural period, existence of two wave group was found at both site. One wave group has the same dispersion characteristics of Love wave and the other is traveling with high phase velocity compared with the shear wave velocity of base layer. In the frequency-wavenumber spectrum, there is no evidence of existence of Rayleigh wave in this frequency range.
