Two dams that everyone knew were failing burst in the night, and a Mediterranean city is washed into the sea
Engineers had warned for years that the dams above Derna needed repair. A decade of war meant nobody repaired them. When the storm came, they broke, and took a quarter of the city with them.
Torrential rain from Storm Daniel overwhelmed two ageing dams above the coastal Libyan city of Derna late on the night of September 10, and when they burst, a wall of water several metres high swept through the sleeping city and carried whole neighbourhoods, with the people in them, into the Mediterranean. The death toll is uncertain in the way that only the worst disasters are: authorities and aid agencies have counted more than 11,000 dead and list thousands more missing, and the true number may never be known, because so many were swept out to sea and because Libya, split between two rival governments and a decade of chaos, has no single authority able to count its own dead.
What makes Derna unbearable is that it was foretold, in writing, by name. A hydrologist at a Libyan university published a paper in 2022 warning that the two dams above the city were in poor condition, that maintenance had lapsed, and that a large flood could cause "a catastrophe" for Derna's residents. Funds had been allocated for repairs years earlier and, in a country carved up by militias and rival administrations, never spent as intended. The dams had not been properly maintained since before the 2011 revolution. So the warning existed, precisely, with the city named, and the maintenance that would have answered it was eaten by the same disorder that then left no one able to sound an alarm or manage an evacuation when the water came. This paper has written the sentence too many times this year: the warning was on paper, and it did not reach the people in the houses. Derna is that sentence written in its most terrible form.
