This paper presents a comparison of the calendar range of individual paleoearthquake calculated by conventional calibration, Bayesian analysis of series of peat samples as well as depth-age wiggle matching. The results suggest that: 1) the Bayesian analysis provides an excellent means to enhance chronological resolution when applied to a series of radiocarbon dates from sections with clear stratigraphic relationships; 2) the calendar ranges of series of samples collected from the same peat but different sampling thickness were compared with that of depth-age wiggle matching; 3) the calendar range of paleoearthquakes constrained by the Markov Chain Monte Carlo (MCMC) Bayesian analysis model; and 4) therefore, the calendar interval of the paleoearthquake event on the middle segment of Huaiyuan Fault was inferred as 1 340～1 114 cal a B.P. (2σ) by the above systematical comparsion.
