In order to invert phase velocities of transverse component of microtremors for S-velocity structure of soil deposits, array observations of two perpendicular horizontal components as well as vertical one were carried out in the reclaimed land of Ogura-Ike pond. Phase velocities of three components were derived from frequency-wavenumber spectra for each component. The results obtained are as follows. (1) All the three components of microtremors come from N24°W direction. This suggests that most sources of microtremors are distributed in the Kyoto city area. V-component is composed of Rayleigh waves and T-component of Love waves. It is likely, however, that microtremors for each frequency are composed of plural modes rather than single mode, especially for frequencies higher than about 3.0Hz. Since it is difficult to identify the mode to which the velocity obtained belongs, the phase velocity of T-component may not be useful for S-velocity inversion. (2) Phase velocities of T- and R-component are nearly equal. For frequencies higher than 3.5Hz, power spectra of T-component are almost always larger than those of R-component and for frequencies lower than 3.5Hz, it is not always the case. (3) As a result of comparison between phase velocities of R- and V-component, they are found to be different unexpectedly.
