For one strong earthquake, the spatial distributions of the anomalies which include medium term anomalies of one year scale, short term anomalies and imminent anomalies, and underground water stations without the anomalies were mainly related to the causative mechanism and active master faults (active abyssal faults or strongly active faults) around the focal region; The spatial distribution of the anomalies coincided with the specific relation among the anomalies, the focal site, the causative mechanism and active master faults. Finally, the mechanism of the relation was briefly discussed, and the importance about the research result in this paper was set forth.展开更多

The water radon concentration is regular to monitoring indicator. The research on the formation of the earthquake radon anomalies (ERA) will produce great academic value and economic benefits. The ERA in slope-type can be seemed as a response of underground water radon anomalies in the progress of tensile stress accumulating.展开更多
