Hungary’s largest ecological disaster took place on October 4, 2010 at 1:30 p.m. when the western dam of cassette X of the sludge reservoir, belonging to a privately owned company, Magyar Alumínium ZRt (Hungarian Aluminum Co), had ruptured. Due to the ruptured dam, a mixture of 600-700 thousand m3 of red sludge and water inundated the lower sections of the settlements of Kolontar, Devecser and Somlovasarhely via the Torna creek.
The spilling red sludge flooded 800 hectares of surrounding areas. The most extreme devastation was caused in the villages of Devecser and Kolontar, which are located near the reservoir.
