What if the dam fails?

Rogun Dam safety has always been a concern, as the location selected for construction sits atop of a seismic fault and a salt dome. The lengthy construction process was several times arrested and reverted by floods and earthquakes. At present experts raise concerns about poorly explored landslide-prone slopes, with one of those threatening to block Vakhsh immediately below the Rogun Dam.

Despite all those risks no transboundary emergency plan has been presented to downstream population, neither any mitigation and compensation mechanism has been discussed for not an unlikely case of dam failure or other major accident.
