| Abstract: | Recordings and materials of 232 earthquakes （ML≥2. 0） and 83 blasts happened during 2008 to 2010 in Ningxia were compared and analyzed by MSDP system simplex location method and HYP2000 location method in the earthquake epicenter, focal depth and the residual distribution three aspects. Compared to MSDP system simplex location method, epicenter is nearer to fracture zones when adopting HYP2000 location method, minor earthquake swarms are more concentrated, the distribution of epicenter depth is more practical, and the distribution of residual error is significantly smaller. Hence, HYP2000 location method should be adopted preferentially when near earthquakes happen. |
