Abstract：Based on digital seismic waveform data from 2000 to 2016 recorded by Anhui network, the paper estimates the apparent stress level in "Huoshan Seismic Window" region, and concludes that average stress is 0.010 8 MPa, which is the background stress level of the region. Meanwhile, the paper analyzes the spatial and temporal characteristics of earthquakes that meet the magnitude and distance conditions in East China since 2000. The results show that: apparent stress in "Huoshan Seismic Window" have four groups high value anomaly within two years, three corresponding earthquakes occurred in East China, and it is inferred that there may be some correspondence between the apparent stress level and the moderate strong earthquakes in East China; the spatial distribution of apparent stress in "Huoshan Seismic Window" show that the high value area mainly is mainly located in the Mozitan-XiaoTian fracture, and is close to the intersection area of Mozitan-XiaoTian fracture and Luoerling-Tudiling fracture, which deserves further attention.
