| 摘 要： | 首先介绍了地震形成的模式,以及断层气的观测事实,并在理论上进行了分析。在此基础上,对2004年12月26日印尼苏门答腊地震震前26个月、震前8 d和震后6个月震区大量气体释放现象进行了分析。结果认为,这种释放是间断性的、不连续的,类似于火山爆发。三次排气的成分也各不相同,第一次是CO;第二次是水汽,属于中地壳低速带气圈;第三次是He、N2、Ar,属于更深部岩石气体,这标志着岩石深部有气体溢出。 |
| 关 键 词： | 地震 断层气 水汽 苏门答腊岛。 |

| Abstract: | At first,the earthquake forming model and the observation facts of fault gases are introduced and theoretically analyzed.Based on it,the massive gas-release phenomenon in seismic region 26 months and 8 days before and 6 months after the Sumatra earthquake in Indonesian on December 26,2004 are analyzed.The result says that,this kind of release is discontinuous,similar to volcanic eruption.The ingredients of the three exhausts are also different.The first is CO.The second is water vapor from the gas-sphere of middle crust low-velocity zone,and the third is He,N2 and Ar from the deeper rock gas,which indicates the overflow of deeper rock gas. |
| Keywords: | Earthquake Fault gas Water vapor Sumatra oceanic area |
