4.2 earthquake occurred in Xuwen County, Guangdong Province at 07:43 on November 22, 2015. The Hainan Strong Motion Network Center collected three sets of three-direction acceleration records, which was the first time to record strong motion seismic waveform after the completion of Hainan strong motion network. After conventional processing, the corrected peak ground accelerations (PGA) of nine zero-baselines were obtained. The PGA records of three stations were analyzed. And the corrected time-history curves of acceleration, velocity, displacement and acceleration response spectrum were plotted, which could provide reference for earthquake damage investigation in Southern China. The results exhibited that the PGA values of the strong earthquake were ranged from 0.8 to 10.2 cm/s², and the maximum PGA value was recorded at Huoshankou Staion (HSK) which is closest to the epicenter.
