Abstract

The invention relates to an earthquake precursor anomaly identification and earthquake prediction method based on soil radon. The earthquake precursor anomaly identification and earthquake predictionmethod comprises the steps of: judging the position of a fault zone in an earthquake activity region, researching the distribution characteristics of the fault zone, arranging soil radon monitoring points in a section with soil coverage to carry out real-time monitoring on the soil radon concentration of the fault zone, and transmitting data back to a monitoring center by means of the soil radon monitoring points in real time; combining meteorological and seismic data, identifying meteorological, seismic and precursor soil radon concentration abnormal information, and preliminarily eliminatingsoil radon concentration anamaly caused by external interference; and setting a soil radon concentration rise threshold value caused by earthquake precursor and a soil radon concentration rise threshold value caused by earthquake. By adopting the earthquake precursor anomaly identification and earthquake prediction method, the soil radon concentration change of each monitoring point is monitoredin real time, soil radon concentration abnormal information of the earthquake precursor is automatically identified, and when the soil radon concentration change of the plurality of adjacent monitoring points exceeds the threshold value, the monitoring center performs automatic early warning to realize earthquake prediction.

Description

technical field [0001] The invention relates to an advanced earthquake prediction technology, in particular to a soil radon-based earthquake precursor anomaly identification and earthquake prediction method. Background technique [0002] Earthquake prediction has always been a worldwide problem. After years of development, earthquake prediction methods have gradually increased. There are methods such as ground stress, natural electric field, infrasonic wave, radon, animal anomaly, satellite thermal infrared remote sensing, magnetic storm double method, earthquake cloud, and tidal force resonance anomaly superposition. Among them, the method of radon measurement and prediction of earthquakes is a relatively important method now. Now it is mainly to observe the anomaly of radon in groundwater to judge the precursor of earthquakes. The method is not sensitive enough to predict earthquakes that are far away from the monitoring point or weak, and cannot judge the direction of th...
