The invention relates to an earthquake precursor feature screening analysis method and system and a storage medium. According to the method, a plurality of monitoring points are arranged in a to-be-monitored area according to the actual monitoring precision requirement, the monitoring data of earthquake precursor signals at the monitoring points at different time and the time when an earthquake event occurs within the monitoring time are monitored, and the monitoring data of a preset time period before the earthquake event occurs are counted to extract the abnormal characteristics of the earthquake event; and the correlation between the abnormal characteristics and the earthquake events is analyzed, so that the earth surface and buildings near the measured point do not need to be damaged, high-quality data input is provided for construction of an earthquake prediction model, and the accuracy of earthquake prediction can be remarkably improved. And the to-be-monitored area can be monitored for a long time through the fixed monitoring station, and the implementation feasibility is good.
Description
technical field [0001] The invention relates to the technical field of data processing, in particular to an earthquake precursor feature screening and analysis method, system and storage medium. Background technique [0002] Earthquake is a natural disaster that has great harm to human society and has caused huge social and economic losses to human society. China has frequent earthquakes and is one of the countries most affected by earthquakes in the world. In order to try to solve the problem of earthquake monitoring and prediction, the AETA multi-component earthquake monitoring system has been developed. It is hoped that a complete monitoring network will be established through low-cost, large-area, and high-density equipment deployment to capture relatively consistent precursory anomaly signals and serve earthquake prediction. . Although the system has achieved rich research results in the existing characteristic data, the existing characteristic data has the problems o...
