摘要
为验证和检验强震临震微波动现象及其主要特征,利用甘肃、青海、四川、云南、西藏等区域台网200余个宽频带数字地震台站的实时波形资料和实时跟踪监控技术系统,对2019-2022年间青藏高原发生的44次5级以上地震进行全程实时跟踪及动态监控,进一步检验临震微波动现象的重现性和客观性,验证了临震微波动现象的频谱、时间、空间等特征.
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.
