【摘要】 对泰安地震台记录的2010年9月4日新西兰地震波形,进行震相、震源深度等地震参数辨析和分析,以具有代表性的2009年7月15日新西兰南岛西海岸远海地震波形和2010年4月5日墨西哥地震波形分析为辅,提出震中距大于83°、小于105°的类新西兰地震分析方法。根据两个辅震的波形特性,结合中国地震台网中心定位结果,对震级误差和波形特征进行解释,提出震级修正方案。更多还原

【Abstract】 The phase and focal depth of New Zealand earthquake on 4 September 2010 recorded by Taian Fiducial Seismic Station was distinguished and analyzed.Assisted by the analysis of typical seismograms of Mexico earthquake on 5 April 2010 and South Island open sea,New Zealand earthquake on 15 July 2009,the analysis method of resembling New Zealand earthquakes whose epicenters between 83°and 105°.The cogitation process and methodology is provided for stations invested the errand of rapid report of large earthquakes.According to the wave character of the two assistant earthquakes and the orientation result of the two assistant earthquakes by China Earthquake Networks Center,the earthquake magnitude errors and wave characters of the two earthquakes were explained.A magnitude modification technique was provided for stations undertaken quick report for large earthquakes to China Earthquake Networks Center.更多还原
