北京地震台远震Pn、PnPn波分析
The analysis of phase Pn and PnPn that recored in tele-earthquake on Beijing Seismic Station
摘要
Abstract
During the work of making the typical seismic atlas of the broadband seismic record of NCDSN Beijing Seismic Station, we found the first arrival phase that recorded in the far distance of epicenter 16. 8° earthquake was still the Pn, and the phase PnPn as the obvious characteristic semismic phase was recored continuously to the distance of epicenter about 30°. In this paper, it tries to show and prove the characteristics and the existence evidences of the teleseismic Pn and PnPn, and also tries to explain the reasons of the PnPn amplitude is much larger than the Pn amplitude several times.关键词
