The continuous waveform data three days before and seven days after the M_S6.9 earthquake in Menyuan, Qinghai Province on January 8, 2022 were recorded by the permanent stations of Gansu seismic network and the shared stations of neighboring provinces. In this paper, the aftershock sequence was detected by the automatic cataloging program based on the data, and the results were compared with the manual cataloging results. It was found that the results of automatic catalogue and manual catalogue are basically the same; the average epicenter position difference is within 5 km, and the magnitude difference is between M_L-0.2~M_L0.2. The earthquake occurrence time from automatic catalogue results is slightly earlier than that from manual catalogue,but the difference of the occurrence time of most aftershocks in the two catalogs is within 2 s. The output speed of automatic cataloging is fast, so it could detect small aftershocks that cannot be recognized manually, thus improving the completeness of the catalogue. On the whole, the output results of the automatic cataloging system can meet the expected objectives, and can provide data support for relevant scientific research, such as earthquake swarm trend judgment and rapid inversion of rupture process.
