Abstract

The differential attenuation beneath the Gauribidanur seismic array has been estimated using the spectral ratio method. Deep focus earthquakes originating in the Hindukus region have been considered for this study. In fact, the estimated Q is the combined effect of the intrinsic attenuation and the attenuation due to scattering. The estimated standard deviation and mean of the differential attenuation have been found as 0.18 s and -0.06 s for the array, respectively. The Q<sub> GBA</sub> is estimated to be 25. It is significant enough and may be due to the scattering by the inhomogeneities beneath the array. __
