According to Cao Shanyou, deputy head of Qiaojia County, the earthquake has caused damage to a total of 1,907 residential houses and eight school buildings, primarily exhibiting minor cracks. Throughout the county, 466 cases of slope collapses and rockfalls on roads, as well as 483 sites of road surface damage, were recorded.
