27 Aug 1986, Wum, Cameroon — A herd of dead cattle is seen in a forest clearing near Wum, Cameroon, following the release of toxic gas from Lake Nyos. In August of 1986, the lake, which is located in a volcanic crater, released a massive cloud of carbon dioxide, killing over 1,700 people and thousands of livestock animals as the deadly cloud descended through the surrounding valleys. | Location: Near Wum, Cameroon. — Image by © Thierry Orban/Sygma/Corbis
