河南省测震台网背景噪声特征分析
|
摘要
利用河南省测震台网2008~2012连续波形数据,通过计算三分量地震计记录到的波形数据的功率谱密度和相应的概率密度函数,对河南省全省测震台网背景噪声进行分析。结果表明,背景噪声与人文、自然环境以及区域第四系覆盖厚度相关,深井架设方式能有效降低高背景噪声干扰。通过分析不同类型台站的背景噪声特征,为台站优化改造及新台建设提供依据。
Using the continuous waveform data observed by seismic network of Henan province from 2008to2012,we analyzed the ambient seismic noise in Henan province by calculating the power spectrum density(PDS)and probability density function(PDF).Using the PDF,we can provide an important basis for quantitative assessment of the seismic data quality,seismic station optimization and construction.
