- Abstract:
-
In order to study the prediction efficiency of the water level in the observational wells,and to explore the relationship between the water-level anomaly and the earthquake,we process the observed water-level data of Deyang Well,Jianchuan Well,Zuoshu Well and Menyuan Well by the difference method and the tidal load-unloading ratio method.Then,using the Molchan chart,we test the prediction efficiency of the 4 monitoring wells for the prediction of the occurrence-time,and the magnitude of the earthquakes in different blocks.The results show that the water level in the 4 monitoring Wells are efficient for the prediction of earthquakes which may occur within 180 days,and effect for the prediction of the moderate- and strong-earthquakes within a certain range.The prediction efficiency is affected by the distribution of tectonic structures; in the structure-developed areas,the water-level anomaly is efficient for the earthquake prediction.
