地下流体对地震前兆作用的综述

Overview on the action of subsurface fluid to seismic precursor

地下流体及流体力普遍存在且对地震前兆产生作用。本文从前兆机理、实例等方面综述了地下流体及流体力(包括降水等产生的力)对地震前兆的作用,表明降水等产生的地下流体及流体力对地震前兆的作用不可忽略,无论是浅层地下流体还是深部地下流体均影响前兆异常的产生,且地下流体对地震前兆的作用是在特定的地质构造、水文地质环境下发生。

Subsurface fluid and fluid force exist universally in crust and act on seismic precursor. From mechanism and examples, the action is discussed here. The results show that, the action can not neglect, and occurs only in special geological structure and hydrologic geology environment, no matter is produced by shallow or deep fluid.
