【摘要】 本文提出了一种在近震条件下,确定台阵三分向记录图中Pg波震相的初至识别方法,并对美国UPSAR台阵记录到的2003年发生在圣西门(San Simeon)地区6.5级的地震数据进行了Pg波震相分析和识别。分析结果表明,本文提出的震相识别方法是有效的。更多还原

【Abstract】 This paper presents a method which can be used in identifying arrival time of Pg-wave for near earthquakes by three-component seismic acceleration data of seismic array.Taking San Simeon M6.5 earthquake recorded in 2003 as an example,a case study is performed from UPSAR dense accelerometer array near by Parkfield in mid-California.The result shows that the proposed method is effective.更多还原
