At least 400 people have been killed by the mudslide that swept through Sierra Leone’s capital, Freetown, on Monday morning. Another 600 are still missing, as rescue workers desperately hunt for survivors.
Freetown is an overcrowded city of more than a million, many living in makeshift settlements which are easily washed away in frequent heavy rains and floods. A key objective at the moment is to avoid the disaster being made worse by water-borne diseases such as cholera, typhoid and diarrhoea.
Probably the deadliest mudslide ever was the one that hit Venezuela in the dying days of the last millennium in December 1999. It effortlessly swept away the shanty towns precariously perched on ridges around the capital Caracas.
But smart apartment blocks also found themselves buried under the mud. Most estimates put the number killed at around 30,000, with 140,000 left homeless, and more than 20,000 homes destroyed. For the story, see A Disastrous History of the World.
