摘要
Deterministic, probabilistic and composite-grading methods are used to get the possible locations of strong earthquakes in the future in Northwest Beijing and its vicinity based on the quantitative data and their accuracy about active tectonics in the research area and by ordering, some questions in the results are also discussed. It shows that the most dangerous fault segments for strong earthquakes in the future include: segments B and A of the southern boundary fault of the Yangyuan basin, the southern boundary fault of the Xuanhua basin, the east segment of the southern Huai'an fault and the east segment of the northern Yanggao-Tianzhen fault. The most dangerous area is Yangyuan-Shenjing basin, the second one is Tianzhen-Huai'an-Xuanhua basin and the third dangerous area are Wanquan-Zhangjiakou and northeast of Yuxian to southwest of Fanshan.
