Red mud has been flowing into River Sajó for two weeks

The Ajka alumina plant accident or the so-called “red mud catastrophe” in 2010 was one of the biggest environmental disasters in Hungary. An industrial accident at a caustic waste reservoir chain took place at the Ajkai Timföldgyár alumina plant. On 4 October 2010, the northwestern corner of the dam of reservoir number 10 collapsed, freeing approximately one million cubic metres (35 million cubic feet) of liquid waste from red mud lakes.

The mud was released as a 1–2 m (3–7 ft) wave, flooding several nearby localities, including the village of Kolontár and the town of Devecser. Ten people died, and 150 people were injured. About 40 square kilometres (15 sq mi) of land were initially affected. The spill reached the Danube on 7 October 2010.
