     There exited medium,short,impending term anomaly in the seismic activity,underground fluid precursors and comprehensive prediction scheme for short-impending term earthquake dynamic tacking in the experimental site of the western Yunnan before Tengchong M5.2 double earthquakes on Jun.20 and Aug.9,2011.Seismic activities which included low frequency activity of M≥5.0 earthquakes,seismic belt activity of M≥3.0earthquakes and precursory earthquake swarm activity of M≥4.0 earthquakes have the medium,short,impending term anomalies in west Yunnan.Underground fluid precursors such as water Rn,water Hg,CO2 and flow of water also appeared short-impending term anomaly,accordingly,there exited medium,short,impending term anomalies in the synthetic prediction scheme of short-impending dynamic tracking in the experimental site of the western Yunnan.Under the guidance of gradual prediction idea in long,medium,short,impending term,we comprehensively analyzed short-impending term anomaly approaching with time step by step,and filled in short-impending term prediction card on Jun.16,2011 to made an accurate short-term prediction （including three elements of earthquake） for Tengchong M5.2 double earthquakes on Jun.20 and Aug.9,2011.
