This paper introduces the discovery of short-term anomalous fluctuations before the earthquakes and the progress of related researches carried out over the years by analyzing the residuals of astronomical time and latitude observations and analyzes the anomalous changes of the latitude and longitude residuals of the astronomical latitude and longitude in different regions and the earthquakes in the surrounding areas And the characteristics of abnormal variation of residuals.The paper discussed the abnormal fluctuations of astronomical latitude and longitude residual errors caused by the anomalous changes of local plumb line and the significance of vertical variations of astronomical and observational latitude and longitude monitoring The possibility of developing this phenomenon to be an effective short-term precursory to strong earthquakes is discussed, and the current situation and problems that should be paid attention to in this research are discussed.A new experimental system for the development of a new type of high-precision automated celestial body measuring instrument Network to further develop the study and optimize the observation and extraction of anomalous information for short-term earthquake prediction methods such as recommendations.
