An aerial photo taken on 05 October 2010, on the broken wall of the reservoir of the Ajka alumina factory in Kolontar, 167 kms southwest of Budapest, Hungary. Previous day the chemical sludge flooded the area between Ajka and Devecser. So far one million cubic metres of the chemical red sludge has leaked and it continues to pour endangering thousands of people with an ecological catastrophe. Four people including two children died due to the dam bursting. Around 80-90 people have been threated in hospital with chemical burns. The Hungarian government declared a state of emergency in Veszprem, Gyor-Moson-Sopron and Vas counties.
