1966 Plakalnitsa tailings dam failure

Around midday the tailings dam of the Mir-Placalnica zinc and lead mine, sited uphill of the village of Sgorigrad in northern Bulgaria, gave way. The resulting mudflow of some 450,000 cubic metres swept away the village and ran seven kilometres as far as the town of Vratza.
