就目前的认识而言,把地磁作为地震预报的一种有希望手段的依据是: 地磁学的研究成果为以磁报震工作提供了必要的知识,一则地磁观测已经有了比较成熟的技术,再则已积累了分析震磁效应的正常背景规律。 观测的物理量意义明确,干扰因素比较清楚,而且已经有了一些排除干扰、提取震磁信息的方法,积累了一些较为可信的震例分析结果。
As far as the current understanding is concerned, geomagnetic as a promising means of earthquake prediction is based on the fact that the research results of geomagnetism provide the necessary knowledge for the application of magnetoclasts. One of the more mature techniques for geomagnetic observations , Then the normal background law of analyzing the seismic magnetic effect has been accumulated. The observed physical quantity has clear meaning, the interference factor is relatively clear, and there are some methods to eliminate the interference and extract the magnetism and magnetism information, and accumulate some credible earthquake analysis results.
