RIS mechanism of concordance between reservoir water weight and tectonic stress of fault

RIS is one of seismicity phenomena its mechanism is still in discussion.In order to discuss the RIS mechanism futurly based on former study the elements of RIS mechanism is analyzed.It is concluded that the concordance of reservoir water weight and tectonic stress of fault is the key condition of RIS activity.The function and process of the concordance of reservoir water weight and tectonic stress of fault is major mechanism on tectonics-physics of RIS phenomena.
