摘要
对青海省1990年以来年度地震危险区进行了分析,整理总结了青海省年度地震危险区的分布、预测面积及地震对应情况,得出预测正确率为52%。将预测基本准确的地震危险区进行归并,得到确定的地震危险区共有5块:祁连地震带、三湖地区、库玛地震带东段甘青川交界地区及共和地区、唐古拉地区、茫崖地区。对历史地震危险区的整理和初步研究,对今后地震趋势预测研究积累一些值得参考的认识和经验。
It is analyzed the yearly seismic risk areas in Qinghai province since 1990 ,and summarized its distribution, predicted areas, and the results showed that forecasting correct ratio is 52%. The correctly forecasting areas are five blocks, they are Qihan earthquake belt, three lakes area, east of Kusaihu - Maqu earthquake belt and Gonghe area, Tanggula area, and Mangya area. And this is helpful to study the earthquake prediction by the analysis.
