- Abstract:
- In order to analyze the anomalous characteristics and the earthquake-prediction efficiency of the hydrogen in Panjin 1st well,Liaoning Province,we firstly eliminate the background interference with hydrogen,then we discriminate hydrogen anomalies by the help of seismicity and the principle of critical slow-down in the stuy area.The results show that the anomalous,high-value fluctuation of hydrogen concentration in Panjin 1st well since October 2019 was closely related with the enhancement of the tectonic activity in South Liaoning Province and the Bohai Rim region,and the enhancement of the earthquake swarm in Gaizhou region.This high-value anomaly of the hydrogen is supposed to correspond to the 2020 Guye MS5.1 earthquake.Further,we use R-value to test the prediction efficiency of the hydrogen in Panjin 1st well.We get that the R-value of hydrogen in Panjin 1st well is 0.48,Which is higher than the R-value of the underground fluid in Liaoning Province.This suggests that the hydrogen in Panjin 1st well can be used for earthquake prediction in Liaoning Province.
