Seismic waves of PP and SS as earth’s surface reflection wave，as a result of the reflection of the earth’s surface，a seismic phase that can be observed in distant earthquake records． The paper used the underground seismographic data to study seismic phases of the 2003 Songyuan earthquake clusters and 2005 Lindian earthquake records，and calculated the arrived time at the selected surface conducting seismic reflection point with the earth’s crust velocity model at the stations near the logging data． The results show that the underground seismographs in specific epicenter of the local earthquake can record reflection waves on the earth surface． The paper determined the seismic phase as PgPg and SgSg in order to differentiate them from the distance records of PP and SS．
