We first use the Python crawler technic to download the high resolution earthquake catalogue automatically. We proposed an effective repeat earthquake elimination method to remove the repeat earthquakes among different catalogues uploaded from different provincial earthquake bureaus. In the end,we transform the high resolution earthquake catalogue to EQ3 format based on the research of its binary structure. Practical application shows that the proposed program can improve the efficiency of the update of earthquake catalogue. In addition,high resolution earthquake catalogue is beneficial for us to analyze seismicity more deeply.
