- Abstract:
- The real-time intelligent seismic processing system(RISP)based on deep learning monitored the May 1-14,2022,earthquake sequence in Qingzhou,Shandong Province,and identified more earthquakes than manual identification,boasting a 90.14% accuracy rate.The exceeding earthquakes identified by RISP system do have seismic signals.The undetected events do not meet the trigger conditions of RISP system and have no automatic processing results.The positioning accuracy of RISP system is equal to that of the manual results,and other seismic parameters like original time,epicenter position,focal depth,etc.are in consistent with the manual results.However,the magnitude given by RISP system is slightly larger than that of the manual results.Based on the distribution and the inverted source mechanisms of the Qingzhou earthquake sequence,the Zhangdian-Renhe fault is supposed to be the seismogenic fault of the Qingzhou earthquake sequence.RISP system is proved to be capable of detecting more micro- and small-earthquakes.It has high accuracy for earthquake location,it does rapid analysis of seismic phases,but it does not depend on manual experience.
