| Abstract: | Using the observation data recorded over the same bandwidth and with the same type of seismometer BBVS-120, the base ambient noise, the earthquake monitoring capability, and the seismic phase characteristics of the new and old observation caves of the Gaotai seismic station were compared and analyzed. The results indicated that the seismic monitoring level of the new cave is better than that of the old and that some new caves have clearer records of radially reflected waves. |

| Keywords: | new and old observation cave comparison of base environmental noise seismic recording capability analysis comparison of recorded features of seismic phases |
