| Abstract: | Based on the calculations of the precise leveling data taken from 1950 to 1980 in bothsichuan and adjacent regions, the velocity map, the gradient contour and distribution map ofgradient vector are drawed. According to both characteristics of seismotectonic zone andthese maps, we predict possible areas where an earthquake will occurs. |
