Abstract: | Using the data set of about 1 Hz Lg amplitudes from 80 stations in the six eastern provinces of China, the ratios of horizontal to vertical amplitude of Lg waves,H/Z are determined. The mean lg(H/Z)-value is equal to 0.13. For the station bases of soft deposit,granite and sedimentary rock, lg(H/Z)-values average 0.55, 0.04 and 0.10, respectively. For the three kinds of station bases, the station terms of horizontal amplitude,C h average 0.65, ?0.09 and 0.00; that of vertical amplitude,C z average 0.32, ?0.04 and 0.00, respectively. There are the relations betweenC h ,C z and lg(H/Z):C h =0.01+2.10C z andC h =?0.15+1.46 lg(H/Z). |
