| 摘 要： | In this paper, the method which can combine different seismic data with the different precision and completeness, even the palaeo-earthquake data, has been applied to estimate the yearly seismic moment rate in the seismic region. Based on this, the predictable model of regional time-magnitude has been used in North China and Southwest China. The normal correlation between the time interval of the events and the magnitude of the last strong earthquake shows that the model is suitable. The value of the parameter c is less than the average value of 0.33 that is obtained from the events occurred in the plate boundary in the world. It is explained that the correlativity between the recurrence interval of the earthquake and the magnitude of the last strong event is not obvious. It is shown that the continental earthquakes in China are different from that occurred in the plate boundary and the recurrence model for the continental events are different from the one for the plate boundary events. Finally the seismic risk analysis based on this model for North China and Southwest China is given in this paper.

| Abstract: | In this paper, the method which can combine different seismic data with the different precision and completeness,even the palaeo-earthquake data, has been applied to estimate the yearly seismic moment rate in the seismic region.Based on this, the predictable model of regional time-magnitude has been used in North China and SouthwestChina. The normal correlation between the time interval of the events and the magnitude of the fan Strong earthquake shows that the model is suitable. The value of the parameter c is less than the average value of 0.33 that isobtained from the events occurred in the plate boundary in the world. It is explained that the correlavivity betweenthe recurrence interval of the earthquake and the magnitude of the last strong event is not obvious. It is shown thatthe continental earthquakes in China are different from that occurred in the plate boundary and the recurrencemodel for the continental events are different from the one for the plate boundary events. Finally the seismic riskanalysis based on this model for North China and Southwest China is given in this paper. |
