一种震前超低频密度—应力波
|
摘要
地震发生前天文时纬残差观测数据出现异常,得到了不同天文台观测结果的证实。另外,两种与地震相关的物理量震前地下深部物质视电阻率变化和断层活动矩变化,其物理机制的解释以及与后续地震的关联方式和天文时纬残差有很多共性。而且,这3类观测现象与后续地震的关联方式与国外学者提出的热力学弹性回跳模型符合得很好。本文基于现有观测证据和理论模型的一致性,提出地震前在地层构造中存在一种来自孕震区域的超低频密度—应力波。
A correlation between astrometric residual anomalies of universal time and latitude prior to earthquakes has been found and repeatedly verified by different observatories.The other two kinds of measurement,such as the anomalies of the earth apparent resistivity and the fault moment before earthquakes,have approximatively the same physical mechanism with the astrometric anomalies mentioned above.These phenomena are coincidence well with the thermodynamical model suggested by some authors.Based on the consistency between observational data and theoretical model,we propose that there exists a density—tectonic stress wave with ultra-low frequency emitted from the epicenter region before earthquakes.
