| Abstract: | Based on two DSS profiles of Tianshui Earthquake Area,we calculated the attenuation apeed change that the maximum amplitude of P-wave with distance in time domain, the attenuated feature of P-wave was obtained. We also calculated the two-dimension Q-value the two profiles,gained the Q-value block distribution in each layer of the crust and the average Q-value columner distribution of each tectonic cells. |
