摘要: 用四点组斜率信息法全时空处理了首都圈全部跨断层短水准和短基线测量资料,然后以观测台站(或测点)为单位,将同一处多条测线的资料进行信息合成,得到了以台点经纬度为坐标,以合成结果为信息量的形变前兆信息的空间分布序列图像。这些图像随时间的变化类似气象云图,对首都圈附近6级以上强震分布的方位有一定的指示意义。

Abstract: In this paper, all the mobile leveling and baseline data across fault in the Capital circle area are processed with Four-point-slope information method, and synthesis is made for the data from different lines at some station. Based on the latitude and longitude of station (or site) and the sy nthetic data, information patterns of crustal deformation are given in series. The variation of these patterns is similar with that of clouds. It has certain significance for indicating the orientation of strong earthquakes with M≥6 nearthe Capital circle area.

Key words: Information synthesis, Fault deformation, Earthquake, Information pattern
