| Abstract: | Using cross-fault levelling data at fixed and mobile observational stations in North China and the North-South Seismic Belt,the vertical displacement rate at each site is cal- culated.The temporal evolution characteristics of cross-fault vertical displacement rate and fault-group synthesized rate before seven earthquakes are studied.The resultindicates that the temporal-spatial evolution characteristics of fault vertical displacement rate are fairly well related to strong earthquake activity.Particularly,the spatial distribution of anomalous displacementrate and its approaching to the source region before an earthquake can be used to predictthe location of earthquake occurrence.The synthesized curve of ver- tical faultdisplacementrate and exceedance ofdeviation limits can be the referential criteri- afor predicting the magnitude and time of the coming earthquakes. |
