After reviewing all precursory anomalies from observation of underground fluid before 2014 Huoshan M_S4.3 earthquake we summarized the general characteristics of these anomalies in temporal and space. The results indicate that the overall precursory anomalies are characterized by compatibility. Temporally,the number of abnormal factors began to increase in about eleven months before earthquake,and the growth rate of the number of abnormal factors speeded up in about three months before earthquake. In the impending stage in about 1.5 months before earthquake,however,some anomalies disappeared,and some abnormal intensity decreased. Spatially,the anomalies mainly concentrated in a distances about 200km from the epicenter. Particularly,the fluid anomalies mainly showed a sudden rise near the epicentral region but a gentle rising in distal region Moreover,the precursor anomaly varies with different observation methods. The effect of fluid temperature,geochemistry such as radon and hydrogen is significant in corresponding to the occurrence of earthquake.
