鉴于马鞍山地区矿山较多,常有人工爆破发生,为了快速识别事件性质,分析了人工爆破与天然地震在P波初动方向、纵横波振幅比、衰减速度、频谱、发震时间等方面的差异。
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.
