| Abstract: | Starting from the definition and significance of quality factor Q value, the main methods and developments of estimating Q value by using natural seismic waves, e.g. body waves, coda waves and Lg waves have been introduced respectively, as well as its corresponding principles and application limits are explained. The prospective on the study of seismic wave attenuation by use of earthquakes is discussed. |
