抄録
A 50 meter modified Michelson interferometer has been installed in an underground tunnel in the Nagatsuta campus of Tokyo Institute of Technology. It is enclosed by vacuum pipes and illuminated by a frequency stabilized 633 nm He-Ne laser. The displacement of the interference fringes is converted to voltage with an accuracy of about 1×10-10. From the spectral analysis of the fluctuations of the interference fringes, it is found that the power spectral densityof the microtremor at the quiet time has peakes at 1 cycle/day and its har-monics, also at 0.3, 0.6, and 3 Hz, and that the values at around 10 Hzincrease when cars pass by on the road near the tunnel.
