“…The high uncertainty and low predictability of earthquakes during forecasting make earthquakes one of the worst natural disasters, which may lead to the instant loss of lives and properties (Gupta, 2001;Wen et al, 2008). The anomalously high concentration of helium, hydrogen, carbon dioxide and radon in hot spring bubbling gas have been widely studied in seismically active faults in recent years, especially in Japan, China, Italy and United States, in hunt of changes that might be premonitory of for earthquake prediction (King, 1986;Sugisaki and Sugiura, 1986;Nagamine, 1994;Cicerone et al, 2009;Babuška et al, 2016;Weinlich et al, 2016;Fischer et al, 2017;Huang et al, 2017). Temporal abnormal variations of gas (He, H 2 , CO 2 , Rn, CH 4 ) concentration have been observed with durations of a few hours to several days before and after a lot of large earthquakes at some gas monitoring stations at the epicentral distances of up to several hundreds of kilometers, which are usually related to the chemical and physical changes occurring in the active faults as enhanced/reduced water-rock interaction, crustal stress/strain, permeability structure, etc.…”
