摘要
利用NCDSN上海金山地震台的宽频带数字地震记录计算了1996年11月9日南黄海6.1级地震的基岩地震动反应谱。与1990年2月10日江苏太仓4.9级地震的反应谱进行了比较，发现这次南黄海地震的长周期地震动成分较为丰富。鉴于这次地震在上海市出现了长周期破坏的事例，指出了研究长周期地震动的必要性和紧迫性。
The bedrock reponse spectra of Southern Yellow Sea earthquake (M 6. 1),November 9, 1996, are calculated by using the NCDSN broad band data of Sheshan station, Shanghai,China. Compared with those of the Taicang Earthquake (M4. 9 ),February 10, 199O,the Southern Yellow Sea earthquake is more abundant in long period component of the ground motion. The necessity and urgency to study long period ground motion are pointed out for the damage of long period structure due to this earthquake.
