We reviewed the current situation of the earthquake catalog report in China,and carried out a comparative study of the focal mechanism and moment magnitude reported by earthquake emergency response agencies and local seismic networks in recent years. The results showed: the seismic moment tensor reported by two emergency units which were Institute of Geophysics and Institute of Earthquake Science,China Earthquake Administration is the rate of 100% for all earthquakes having occurred over the domestic land areas with the magnitude of M≥ 6. 0,and the rate was 81% for M≥5. 0. The three kinds of seismic moment tensor given by the two emergency units was similar with the seismic moment tensor given by GCMT. In accordance with the seismic moment tensor type classification,the statistical concordance rate reached respectively 71%,86% and 66%,where the P,T-axis angle of spatial distribution was mainly about 15°. The difference of the moment magnitude was relatively small between two emergency units and GCMT. The deviation ratios of 0. 1 were respectively 46%,86% and 71% . The variation ratios of 0. 3 were respectively 85%,100% and 97% . The results showed that for the earthquakes over the domestic land areas and magnitude with M≥5. 0 both units output rates are higher and more consistent. The local seismic network reporting moment magnitude about M5. 0 derived from the source parameters and GCMT solving moment magnitude is significantly smaller in comparison. Thus under the current circumstances we discussed the feasibility of an increase of focal mechanism and moment magnitude on the basis of traditional earthquake catalog.
