1976年7月28日唐山发生了7.8级强烈地震,由于震前没有明显的前兆,因而带来了极其严重的后果。为了总结这一教训和重新规划强震地区的工程建设与抗震设防工作,有关唐山地震的形成、震源机制与活动特点、发震断裂的位置与震害效应等这样一些重大问题的研究,正在受到专业部门的高度注意和重视。
On July 28, 1976, a strong earthquake of magnitude 7.8 occurred in Tangshan. As a result of the absence of obvious precursor before the earthquake, it brought extremely serious consequences. In order to summarize this lesson and re-engineer the engineering construction and anti-seismic fortification work in strong earthquake areas, the research on some important issues concerning the formation of Tangshan earthquake, the focal mechanism and activity features, the location of the seismogenic fault and the earthquake damage effect is under way Professional departments pay great attention and attention.
