| Abstract: | Using difference and subordinate function methods in mapseis soft, the anomaly of CO2 in new No. 04 spring is analyzed. The result shows that： ①The abnormal configuration is positive anomaly; ②The reflection earthquake ratio of difference anomaly is 71.4% for the medi- um-strong earthquakes in near region and strong earthquakes in far region; the reflection earthquakes ratio of subordinate function anomaly is 66.7% for medium-strong earthquakes, for strong earthquakes it is 83.3% ; when the two kinds anomalies occurred, the reflection earthquake ratio is 66. 7% for medium-strong earthquakes, it is 100% for strong earthquakes; ③It is direct ratio between the most abnormal range of difference and subordinate function anomalies and epicenter distance. This result can promote the precision of location prediction for earthquake. |
