摘要
用南平台模拟地震记录和数字观测记录 1 999年 4月 8日吉林东部 7级地震的不同深震震相来测定其地震深度 ,结果为南平台用地核界面波测定的震源深度与中国地震台网所测定的深度接近 ,用震中附近反射转换波定震源深度与中国地震台网所测定的深度有一定的误差。对此 ,本文进行了讨论。
The focal depth of the earthquake with M 7 0 occurred in Eastern Jilin on April 8,1999 is determined by use of deep phases of simulation and digital records at Nanping Seismic Station.The result shows that the focal depth determined by centrosphere interface wave is close to that determined by China seismic network.But when we use reflected converted wave around epicentre to determine the focal depth,there is a little error between the results from Seismic Station of Nanping and from China seismic network.We give some discussion on it.
