摘要
本文利用滇西地区近些年来的地震地质、地球物理及地壳形变等方面的资料,经深入研究分析,最终选定了12个较理想的特征参数,通过综合图像识别,在64个研究对象中得到了28个D类对象,占研究区总面积的43%。其中有16个对象历史上已有6级以上地震的记载;12个为新判定的中强地震潜在震源区;1个为判定不稳定对象。最后给出了云南滇西地震重点监视防御区中强地震潜在震源区预测图。
Final 12 more ideal characteristic parameters have been selected by deeply analysing recent data on seismogeology, geophysics and crustal deformation in Western Yunnan area. 28 D-type objects taking up 43% of the total area have been obtained from stkdying 64 objects by means of synthetic pattern distinction. Among the D-type objects, 16 objects have had historical M = 6 earthquake records, 12 have been determined as the new potential focal areas lor moderate-strong earthquakes, 1 has been considered as unstable object. Finally, a prediction map of potential source areas for moderate-strong earthquakes in the intensified monitoring region of Western Yunnan has been presented in this paper.
