利用山东数字化测震单台三分向记录,选择2种测定地震方位角方法和7种数据预处理方法,通过对实际结果的系统对比分析,确定了最佳的测定地震方位角的技术方案和适于地震预警的测震台站。对测定震中距和震级的方法进行了改进,得到了最佳的根据直达P波前2s波形的包络特征参数求震中距、峰值速度的统计关系,以及根据包络特征参数求震级的标度关系。快速测定震中距和震级方法在实时地震预警中具有应用前景。
Based on the single trishase record of digital seismograph in Shandong Province, two methods of seismic azimuth measurement and seven data preprocessing methods are selected. Through systematic comparison and analysis of the actual results, the best technical solution for measuring the azimuth of the seismic and Seismic stations suitable for earthquake warning. The method of measuring the epicenter distance and magnitude is improved, and the statistical relationship between the epicenter distance and the peak velocity is obtained based on the 2s waveforms of the direct P wave front and the scale of the magnitude is obtained according to the envelope characteristic parameters relationship. The rapid determination of epicenter distance and magnitude method has the potential application in real-time earthquake early warning.
