Abstract:
The automatic,accurate detection of the arrival time of the seismic phase is crucial for the earthquake location,and is a prerequisite for earthquake early warning.We use the data acquired by Yunnan Seismic Networks to detect P-wave automatically by the two methods described in the article and get better results which are close to the artificial results.Better results are also gotten when we detect P-wave automatically for some strong,seismic,vertical component recordings by the same method.
