Abstract Moderate to strong earthquakes occur frequently in Keping block. To obtain more judgement basis of earthquakes, based on the earthquake data recorded by Xinjiang Digital Seismic Network, we calculate the apparent stress of ML≥3.0 earthquakes occurred in Keping block from 2010 to 2020. We discuss the scaling relationship of source parameters and analyze the temporal-spatial variations characteristics of apparent stress before and after M≥5.0 earthquakes and Jiashi MS6.4 earthquake. The results show that the apparent stress is positively correlated with magnitude. The apparent stress values show different degrees of temporal and spatial high anomalies before M≥5.0 earthquakes in Keping block. The Jiashi MS6.4 earthquake occurred in the process of high apparent stress, there was an abnormal area of high apparent stress in the epicenter area five months before the earthquake.
