Abstract: In this paper, we briefly specified the origin and contents of the two major catalogs of Chinese earthquakes, the Destructive Earthquake (M_S≥4.7) Catalogue and the Complete Catalogue of Chinese Earthquakes(M_L≥1.0). We also pointed out the differences among these catalogs. We also studied the relationship between M_S and M_L and a new converting formula was recommended. Finally, we provided suggestions to standardize the compilation of earthquake catalogs.

Key words: Earthquake catalogue, Magnitude determination, Surface-wave magnitude M_S, Local earthquake magnitude M_L, Conversion formula
