Abstract：From October 29th, 2012 to March 20th, 2013, The northern Liuzhou significant sequence activities occurred in northern Guangxi. There are 38 earthquakes been recorded, among of them, 3 events with ML range from 2.0 to 2.9, 3 events with ML 3.0. The paper analyzed the earthquake damage characteristics, the macroscopic anomaly, geological tectonic location, spatial distribution range, focal mechanism solution, stress drop, wave velocity ratio, and the level of regional seismic activity for the earthquake sequence. The results show that the northern Liuzhou earthquake sequence belongs to the earthquake activity with high background and is a continuation of the enhancement regional seismic activity, which has certain precursory significance for the Pingguo M4.5 earthquake on February 20th, 2013.
