| Abstract: | Shacheng ML 4.4 magnitude earthquake on August 3, 2002 is a remarkable earthquake in the Capital area in that year. Although its magnitude is not large, the short-term and impend anomalies of body stain in Huailai seismic station is significant. In this paper, the characteristics of the body train anomalies before the earthquake is introduced. The radon anomaly in underground fluid in Sanmafang, Yuanyang and Hg anomaly in Huai4 well are also described. |
