| Abstract: | This paper presents a mechanical seismogenic model due to the multi-segment locking along a fault. Its additional stress field has been deduced and calculated. The. temporal-spatial distribution characteristics of multi-source field before earthquakes have also been discussed. As a result, the comblexity of precursor field evolution and the variety of crustal stress variation before earthquakes have been, made clear. |
