| Abstract: | There are many mines in the Ma'anshan area and artificial blasting is often used. In order to quickly identify the nature of seismic events, the differences of seismic records between artificial blasting and natural earthquakes are analyzed in the respects of P wave first motion, the amplitude ratio of the P wave and S wave, energy attenuation rate, spectrum, and origin times. Rapid identification of event nature can be helpful to efficient emergency work for the earthquake department of a city; in addition, it can also make the seismic catalog more accurate, which is very conducive to earthquake prediction and seismological studies. |
