le="MARGIN: 0cm 0cm 0pt" class=MsoNormal>le="FONT-SIZE: 14pt" lang=EN-US>Based on cross-leveling data analysis, earthquake case study, and R-value assessment, the authors carried out preliminary evaluation of cross-fault level monitoring effectiveness in capital area. The results from finite element modeling, earthquake case study, R-value assessment shows that: 1) the monitoring effectiveness of cross-fault leveling is affected by both fault dip and strike; 2) the station located across fault with dip between 30°le="mso-ascii-theme-font: minor-fareast; mso-fareast-theme-font: minor-fareast; mso-hansi-theme-font: minor-fareast; mso-bidi-theme-font: minor-bidi">le="FONT-FAMILY: 宋体; FONT-SIZE: 14pt; mso-bidi-font-family: ’’Times New Roman’’; mso-ascii-font-family: ’Times New Roman’; mso-hansi-font-family: ’Times New Roman’">～le="FONT-SIZE: 14pt" lang=EN-US>70° and strike perpendicular to crustal general motion has relatively stronger monitoring effectiveness in terms of earthquake prediction; and 3) the cross-fault leveling in the capital area possesses satisfactory monitoring capacity in general.oft-com:office:office" />
