地震震级是描述一个地震重要的参数之一,其精度的优劣直接影响到对于本次地震及其有关方面的研究,尤其对于一次巨大地震来说,震级的精确测定,更为重要。 1976年7月28日发生在我国唐山的7.8级巨大地震,是本世纪以来世界著名地震之一,为各国所瞩目,对于这次地震的震级,至今一直被人们所谈及。本文从中国地震台网记录的动力学读数对7.8级主震和7.1级最大余震的震级测定给予论述。
The magnitude of the earthquake is one of the most important parameters to describe an earthquake. The accuracy of the earthquake directly affects the study of the earthquake and its related aspects. Especially for a huge earthquake, the accurate determination of the magnitude is even more important. The 7.8 magnitude earthquake that struck Tangshan, China on July 28, 1976 is one of the world famous earthquakes of this century, which is attracting the attention of various countries. The magnitude of this earthquake has been talked about so far. In this paper, the dynamic readings recorded by China Seismological Network are used to discuss the magnitude determination of the magnitude 7.8 main shock and the magnitude 7.1 aftershock.
