【摘要】 将McNamara等人(2005)提出的地震噪声概率密度函数(PDF)方法用于地震台站台址勘选测试数据的自动处理,实现了对台址地震噪声水平主要评价指标加速度功率谱密度(PSD)与用RMS表示的速度有效振幅的自动估算,大大提高了台址噪声测试数据的处理速度。该方法已被应用于福建地震烈度速报台网84个新选台址的勘选数据处理工作。更多还原

【Abstract】 The approach of Seismic Noise Probability Density Functions (McNamara,2005) is used to process seismic noise recorded during measurements for seismic station site selections. Using this approach, we can quickly compute all the major parameters for assessments of seismic station site noise, such as the acceleration Power Spectral Density (PSD), the velocity effective amplitude or root mean square (RMS). The speed of seismic noise processing will be increased significantly. This approach has been used in the seismic network of Fujian.更多还原
