On the 4th of October, 2010, hundreds of thousands cubic meters of toxic, virulent red mud poured out from the containment pond of the Hungarian Aluminium Production and Trade Company Ltd. next to the city of Ajka in Hungary. Because of a dam break the spilling sludge of around 600-700 000 cubic meters (21-24 million cubic feet) inundated the lower sections of the villages of Kolontár and Devecser. Ten people were killed, and many hundreds injured because of the mud, which flooded the half of the village Kolontár and the two-third of Devecser, up to two meters high in some places.
