| 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. |
