| 英文摘要 | The 2017 Iraq M(w)7. 3 earthquake occurred in the Baghdad seismic zone defined by us. The seismic type of the earthquake is discussed according to its different magnitude parameters provided by various agencies, and then its post-quake trend in this seismic zone is analyzed in this paper, based on the theory about the brittle failures of multiple locked patches in a seismogenic fault system. The present results show that if the 2017 Iraq earthquake is with a magnitude of M(w)7. 3, it is identified as a significant foreshock occurred in the evolution process towards the peak strength point of the third locked patch, demonstrating that a M(w)7. 7 similar to 8. 2 (or double earthquakes of M(w)7. 5 similar to 8. 0) characteristic earthquake will take place in the near future because the seismic zone has closed to the critical state; if the 2017 Iraq earthquake is viewed as M(w)7. 5, it may yet be one of the double-shock-type characteristic earthquakes besides as a significant foreshock, implying that the other M(w)7. 5 earthquake will strike the seismic zone within two years; if the 2017 Iraq earthquake is viewed as M(s)7. 8, it is identified as a characteristic earthquake occurred at the peak strength point of the third locked patch, which is in good agreement with our prospective medium-to-long term prediction of this earthquake. Furthermore, we judge that the M(s)7.8 earthquake is not a mainshock, demonstrating that the next M(w)7. 8 similar to 8. 3 (or double earthquakes of M(w)7. 6 similar to 8. 1) characteristic earthquake will take place in the remote future because the seismic zone is far from the critical state at present. |
