摘要
Based on initial motions of the three-component P wave data recorded at a single station in Shandong Seismic Network,compared with actual results, the authors established the optimum technical scheme of measuring earthquake azimuth and the stations applying to earthquake early warning from two kinds of measuring earthquake azimuth methods and seven kinds of data preprocessing methods.The authors also got magnitude scaling relation based on the envelope characteristic parameter.The quick measuring method for earthquake epicenter and magnitude exhibits practical application prospect in real-time earthquake early warning.
