本文介绍了天文时纬残差的定义,地震前天文时纬残差出现异常的研究现状,该异常可能的物理机制,以及2008年汶川8.0和2013年芦山7.0地震前云南天文台光电等高仪的时纬残差均出现同步异常。这与30余年的研究实践一致地表明,天文时纬残差震前异常是一种可能的地震前兆,它可以为仪器周围将发生的地震提前给出有价值的预测信息,值得重视和深入研究。
This paper introduces the definition of weft residuals at astronomical times, the research status quo anomalies of astronomical latitude and longitude residuals before the earthquake, the possible physical mechanism of the anomalies, and the photoelectric altimeters of Yunnan Observatory before the Wenchuan 8.0 and 2013 7.0 Lushan Earthquake Temporal latitude residual synchronization abnormalities appear. This is in line with more than 30 years of research practice and shows that the anomalous pre-earthquake anomaly at the astronomical latitude and longitude residuals is a possible earthquake precursor, which can give valuable forecast information in advance for the earthquakes that will occur around the instrument, which deserves our attention and further study .
