Reflecting Earthquake Characteristics and Mechanism Analysis of Different Occurrence Forms of H2
Both dissolved H2 in the Urumqi 04 spring water and the H2 in the soil of the Aksu fault belong to the A-type monitoring points of Xinjiang earthquake monitoring,pre-diction,and evaluation.This paper takes the two as research objects,and analyzes the dy-namic variation characteristics of H2 concentration in different occurrence forms.The R-value scoring method and Molchan chart method were used to test the earthquake-reflec-ting efficiency of H2 concentration and to extract abnormal indexes.The mechanism of H2 reflecting earthquakes in different occurrence forms is discussed and analyzed.The conclu-sions are as follows:The concentration of dissolved H2 in the Urumqi 04 spring water is less affected by meteorological factors,while the concentration of H2 in the soil of the Ak-su fault is influenced by both air pressure and air temperature,mainly by air temperature.The R-value scoring method and Molchan chart method showed that both monitoring points had good short-term prediction efficiency.The good short-term prediction perform-ance of H2 measurement is due to the stable physical and chemical properties of H2 and its extremely fast migration speed.
