| Abstract: | Research 13 typical earthquakes of magnitude 6 or higher in the North China block since 1970. Evaluating the effectiveness of full-time sweep detection of earthquake significantly enhanced anomaly index using Molchan and R values, research on the optimum prediction time and space parameters. Finally, the applicability of earthquake significantly enhanced anomaly index in North China Block is verified, it provides a practical basis for earthquake situation tracking using this method. |
| Keywords: | Earthquake significantly enhanced Seismological anomaly Molchan R Effectiveness evaluation |
