摘要
The average value of the intrinsic shear wave quality factor, Q(beta), has been estimated for the upper 55 km of the earth (47 km of crustal and upper 8 km of the upper mantle thickness) in the border region between the Ganga-Basm and Himalaya in Bihar. We have used the teleseismic Broad-Band SH and SSH waveforms of the 1988 Nepal-India border earthquake (6.4 m(b)) for this purpose. The frequency independent average value of Q(beta) estimated in the range of 0.2-1.5 Hz is found to be 1250 +/- 158. (c) 2004 Elsevier Ltd. All rights reserved.
