Abstract
In this study an improvement of the Nakamura’s spectral ratio is proposed.Using the 3 component recordings of microtremors, it is considered that the vertical component represents the vertical tremor at the substrate, except for the presence of uncorrelated noise (Wv). The horizontal components represent the horizontal tremor (except for uncorrelated noise Wx.
