摘要
Taking the annual seismicity trend reports as an sample, the seismic monitoring and annual earthquake prediction for northeast margin of Qinghai-Tibetan block are tested. The capacity of earthquake prediction using crustal deformation anomalies is evaluated. The results show that there was no pretermission of prediction for moderate-strong earthquake in 16 years, 4 events were predicted correctly and 19 times failed, the accuracy ratio of prediction is about 21%. It is indicated that crustal deformation monitoring has good predictive capacity to moderate-strong earthquake.
