It is found that the typical damage characteristics mainly include rock slope and landslide, fixed glass window damage and building local collapse, rubble masonry structure collapse, and wall cracking. We analyzed the whipping effect of the formation mechanism of the destroyed buildings, and discussed the improved construction measures of anti-seismic capacity of buildings. The measures and reasons of intensity evaluation in the intensity Ⅷ are offered.to provide reference to the earthquake fortification of buildings, the reduction of damage loss, and intensity evaluation. %R %U http://zgdz.eq-j.cn/zgdz/home %1 JIS Version 3.0.0
