WebJan 1, 2012 · The frequency-dependent characteristics of P-and S-wave attenuation in the upper crust of NW Himalayas have been estimated using local earthquakes for a frequency range of 1.5 to 18 Hz. An inversion method is described whereby the intrinsic Q in shear of the earth's mantle is computed from the surface wave and free oscillation data. The restrictions and assumptions in the calculation are (1) Q must be positive, (2) Q is independent of frequency, and (3) the mechanism of energy dissipation is through a complex modulus.
