Tunde Erdelyi saves her cat while Janos Kisri walks into their yard, which was flooded by toxic mud in the town of Devecser, Hungary. A reservoir containing red toxic sludge from an aluminum plant in Ajka broke on Oct. 5, 2010, releasing about 185 million gallons of the poisonous mixture. The sludge inundated three villages, killing eight people and injuring more than 120.
