如若地下岩石中的应力增加,就会产生微裂隙,氢气便会从这些裂隙中释放出来。日本现已开展通过检测这种氢气来捕捉地震前兆的研究。从事这一研究的是茨城县筑波市的工业技术院地质调查所(所长井上英二)。他们研究开发了使用氢感应型陶瓷传感器的氢气测量装置,并投入了静冈县伊东市赤泽地区和神奈川县小田原市国府津地区为防备“小田原附近地震”而进行的观测活动。目前,苏联、中国、美国等国家都在研究利用氡预报地震。利用氢的观测则是日本特有的尝试。与氡的观测相比,它在技术方面更容易些。目前,名古屋大
If the stress in underground rocks increases, micro-cracks will develop and hydrogen will be released from these cracks. Japan has conducted research to capture the precursor of the earthquake by testing this hydrogen. Engaged in this research is Tsukuba City, Ibaraki Industrial Technology Institute of Geological Survey (Ichimiso Inoue). They researched and developed hydrogen gas measuring devices using hydrogen-inducing ceramic sensors and put into observation activities in preparation for preparing for the “earthquake near Odawara” in Shizuoka, Ito-shi, Shizuoka Prefecture and Kokubun region, Odawara City, Kanagawa Prefecture. At present, the Soviet Union, China, the United States and other countries are studying the use of radon prediction earthquake. Observations using hydrogen are Japanese-specific attempts. It is technically easier than radon observations. At present, Nagoya
