地下流体长趋势异常变化与强震预测的初步研究

Preliminary Study on Subsurface Fluid Long-time Trend Change and Strong Earthquake Prediction

以华北、川滇、青藏东北缘、新疆及邻区等重点地区的地下流体观测点为基础,选择水位、水氡、水温、汞等长期观测资料,进行了历史强震震例的地下流体长趋势资料处理、干扰排除和异常提取的方法和技术的研究,初步建立了分区的强地震地下流体长期预测指标并探讨其异同。

In this paper, the procession, disturbing preclusion and anomaly extracted method and technology of suburface fluid long-time trend change data are studied before historical Strong Earthquakes （Ms ≥ 〉 7.0 on west egion or Ms≥6.0 east region in China） on major regions such as North China, Sichuan-yunnan, Northeast ,dge of Tibetan plateau, Xinjiang and its neighboring region. The subsurface fluid long-time prediction indexes of strong earthquake are preliminarily tried to build on different region.
