We summarized the fluid anomalies associated with the Ludian MS6. 5 earthquake based on the Sichuan and Yunnan earthquake network observations and field survey. The fluid anomalies were divided into long-term,medium-term,short-term,imminent and macroscopic anomalies according to the basic principles of earthquake forecasting. The long-term and medium-term anomalies distributed mainly in the range 300 ~ 500 km away from the epicenter. By contrast,the short term,imminent and macroscopic anomalies clustered in an epicentral distance less than 100 km. The underground fluid anomalies in the higher station density area reflect the enhancement of fluid movement,which are conducive to determine the seismic risk area and trace the short-term precursor of earthquake. The regional stress variations may cause the fractures in a fault zone open and close,leading to the change of water level and temperature in boreholes or spring and emission of deep-sourced gases. It may also lead to intense water-rock reaction and groundwater intrusion,resulting in the change of ion contents in groundwater,or sometimes,the occurrence of significant macroscopic anomalies. Therefore,it is highly possible to obtain reliable earthquake precursor information for predicting the forthcoming earthquake risk zone in the region with dense observation stations.
