Abstract:In order to further test the tracking indicators of microwave fluctuation impending earthquake, based on the data from real-time monitoring and tracking system of microwave fluctuation impending earthquake in Lanzhou, we analyze the waveform data recorded by stations within 150 km of earthquakes of magnitude 5.0 and above in Qinghai region from 2020 to 2022. We believe that almost all stations within a radius of 150 km from the epicenters can record impending microwave motion events. The stations that achieve the index of microwave fluctuation impending earthquake anomalies are not the closest to the epicenter. This may be related to regional tectonic stress, strike of seismogenic fault and process of earthquake rupture. Moreover, the larger the magnitude of the main earthquake, the greater the likelihood of the occurrence of the index of microwave fluctuation impending earthquake anomalies.
