在中亚山区的几个地方，有历史和史前时期以前滑坡形成的堰塞湖的证据。地貌记录有助于理解最近的过程：大型山体滑坡反复堵塞湖泊，然后威胁下游的人口。尽管大多数水坝的溃决发生在形成后的头几个月，但湖泊也可能在后期突然干涸。来自巴基斯坦北方的两个案例研究被用来解释有关大坝形成、突出机理和减灾选择的现象。
Evidence of former landslide-dammed lakes exists in several places of the Central Asian mountains, both from historic and prehistoric times. Geomorphic records help to understand recent processes: large landslides repeatedly dam lakes which then threaten the population downstream. Even though most dam failures occur in the first few months after formation, lakes may also drain suddenly at later stages. Two case studies from Northern Pakistan are employed to exemplify the involved phenomena regarding dam formation, outburst mechanisms and options for hazard mitigation.
