Abstract: | In this paper, a numerical model was presented for interpreting the movement feature of an active fault zone. This model was based on the analytic solution, given by Crouch (Crouch, 1976), for the problem of displacement discontinuity in an infinite elastic solid, making full use of geodetic and geological data and it was constructed by the boundary element method. A numerous test computation shows that if you want to catch the possible seismic precursor from the displacement’s vector, you have to associate the computation with geological survey in a deep going way, otherwise you would fail in your propose. This method is valid for analysing the zone of strike-slip fault and it has some values for dealing with other analogous problems. The Chinese version of this paper appeared in the Chinese edition ofActa Seismologica Sinica,15, 153–158, 1993. |
