摘要:
利用ATG-300H便携式测氢仪,对黑龙江省高寒地区肇东痕量氢进行野外定点连续观测,并对泰来3.3级地震震兆关系进行初步分析。结果表明:肇东痕量氢表现为高值突跳,异常幅度大,持续时间短;氢气浓度4组高值异常,表现为“先上升、后下降”趋势,具有持续性和重复性。通过对高寒地区肇东痕量氢异常特征及异常机理分析,为痕量氢资料在地震预测中的应用提供一定的观测依据。

Abstract:
ATG-300H portable hydrogen analyzer was used for continuous observation of spilled hydrogen in the Zhaodong area of Heilongjiang Province. the results show that in the range of 200km away from the observation point, spilled hydrogen is abnormal in Zhaodong before the M3.3 earthquake in Tailai County. Outliers are characterized by high-value leap, abnormal amplitude, short duration, and combined with four abnormal high-value, as the hydrogen concentration strength first increased and then decreased, with the characteristics of continuity and repeatability. Based on the analysis of the abnormal characteristics of spilled hydrogen and the abnormal mechanism of spilled hydrogen in Zhaodong of the high-cold area, this paper provides some factual evidence for the application of spilled hydrogen data in earthquake prediction.
