今年2月7日,中央和各地电台、报刊报道了地震部门对我国近期强震形势的预测意见;1990年前后,地震多发,主要活动区可能在我国西北地区。 1987年,笔者曾两次简介了自己对西部震势的分析意见,认为西部大部分地区还会继续平静(1987年2月20日《中国地质报》、《西北地质》第6期)。无论从地质构造上,还是从历史强震资料来分析,我国西部强震明显受印度板块北移运动所控制。由
On February 7 this year, the central and local radio stations and newspapers reported the earthquake department’s prediction of the recent strong earthquake in China. Before and after 1990, earthquakes occurred frequently and the main activity areas might be in the northwest of our country. In 1987, I briefly introduced myself to the analysis of the Western Earthquake. My opinion is that most areas in the west will continue to be calm (“China Geological Journal” and “Northwest Geology” No. 6, February 20, 1987). Whether in terms of geological structure or historical data of strong earthquakes, the strong earthquakes in western China are obviously controlled by the northward movement of India plate. by
