説明
Clear multiple core phases from east Russian deep earthquakes with epicentral distance about 9 degrees are recorded at the Dodaira observatory. Through the spectral analysis of these core phases such as ScS and sScS group the attenuation factor Q for the upper 600km and the whole mantle is determined. The average Q value in the whole mantle is estimated at 290 for the frequency range 0.015-0.035cps, and that of the upper 600km is estimated at 150, 220, 260 for the range 0.015-0.035, 0.035-0.095 and 0.30-0.80cps, respectively.
