省级地壳形变前兆标志及预报体系应用研究

Study on application for precursor indexes of province-level crustal deformation and prediction system

对形变监测能力相对薄弱的省份建设省级形变前兆标志及预报体系进行了应用研究。内容包括中短期地震形变前兆异常的规范化识别及提取、省级体系的构架设计及建设要点等。以广东地区为例 ,从震例出发 ,确认了γ因子、海平面等 10个省级形变前兆标志 ,并在预报实践中付诸应用。最后 ,就形变标志与地震三要素的关系进行了讨论。

In this paper, a study on the developments of the province-level prediction system and the precursor indexes of crustal deformation has been carried out, in those provinces where monitoring capacity of crustal deformation is weakness velatively. The research contents the normative identify and pick-up of short and medium-term precursor anomalies of crustal deformation, and etc. The study confirms 10 the province-level premonitory indexes with γ factor,and sea-level and so on. Finaly, the relation between premonitory of the crustal deformation and earthquakes discussed.
