| 摘 要： | 震相到时的精确捡拾是地震定位的关键所在,是进行地震预警的前提.对云南测震台网的观测数据进行P波自动捡拾试验.用基于幅值和频率的P波识别方法和STA/LTA方法捡拾到的P波到时,与人工捡拾的结果比较接近,取得较好的结果;用该方法对云南强震台网的部分强震记录的竖向资料进行P波到时自动识别,也获得了较好的结果.

| 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. |
