| Abstract: |
| In order to verify and examine the micro-fluctuation phenomenon and its main characteristics of impending strong earthquakes,the real-time waveform data of more than 200 broadband digital seismic stations in Gansu,Qinghai,Sichuan,Yunnan,Tibet and other regional networks are used to the full real-time tracking and dynamic monitoring of 44 earthquakes of magnitude 5 or above that occurred on the Qinghai-Tibet Plateau from 2019 to 2022,with the base of real-time tracking and monitoring technology system. We further tested the reproducibility and objectivity of the impending earthquake micro-fluctuation phenomenon,and verified the spectrum,time,space and other characteristics. |
| Key words: The phenomenon of microwave fluctuation impending strong earthquakes Prediction index of space-time Verification |
