Immediately after the earthquake, Songyuan Seismological Bureau held an emergency video conference with experts from China Seismological Bureau and Provincial Seismological Bureau to learn about Shang Zhen. The conclusion is that the earthquake with Ms 4.3 in Guo Qian County is the aftershock of the earthquake with Ms 4.9 in Ningjiang, Songyuan on July 23, 2007, and there is no new abnormal change in the precursory observation data near the earthquake area. Comprehensive analysis shows that it is unlikely that a destructive earthquake will occur near the epicenter in the near future, but the possibility of a felt earthquake cannot be ruled out.
