地下流体远场地震效应讨论
|
摘要
本文通过对5级地震前地下流体异常事例的研究得到,地下流体的远场效应是客观存在的。与近场效应相似,远场效应也显示出复杂性,同时远场效应与近场效应无明显差异,这就给地震预报,尤其判断未来震中,带来很大困难。为此有必要开展地震综合预报和地下流体地震综合观测。
In this paper the authors propose that there is objectively the far-field effect of the underground fluids by means of analyzing the examples of underground fluid anomalies occurred before the earthquakes with M=5. Similar to the near-field effect, the far-field one also shows the complexity: there is no difference between the near-field effect and the far-field one, which brings the difficulties to earthquake prediction, especially to judgement of the future epicenters. Therefore, it is neccessary to conduct the comprehensive earthquake prediction and the comprehensive observation of the underground fluids for earthquake prediction.
