Police say rescue officials are worried that water from a choked river could inundate towns near the epicenter. 警方称救援人员担心堵塞的河流一旦决堤将会淹没震中附近地区的乡镇。
The course changes frequently, and the area is so flat that a small change in the level of the river may inundate a considerable area. 河道变化多端，下游地区却很平坦，水位少许上涨河流就会淹没一大片土地。
