Based on the research of earthquake precursor anomaly information

analyze the atmospheric radon concentration data from 2015-01-01 to 2015-05-23

comparing with earthquakes of magnitude 4.0 or more within a range of 1 000 km in the same period

the correspondence rate between atmospheric radon anomalies and earthquakes is about 58.8%. Taking the measured temperature at the time of measurement as the period to divide the atmospheric radon concentration anomaly

re-analyze it to get more earthquake-related radon concentration anomalies. The correspondence rate of atmospheric radon anomalies to earthquakes is about 82.3%

which is about 30% higher than that before segment analysis. Experiments have proved that it is feasible to use atmospheric radon concentration anomalies to analyze earthquake precursors

and the periodic division of atmospheric radon concentration anomalies can help highlight the anomalies and provide auxiliary decision-making for the analysis of earthquake precursor radon anomalies.
