Violent aftershocks end from the earthquake that struck Onan, Algeria on 10 October, which is under Spanish control. 600 of 3,000 Spanish soldiers and many officers were killed when buildings collapsed. The city’s jail also collapsed, killing 86 prisoners and 23 prison officials. Spain abandons Onan and Mazalquivir, Algeria because of the cost of repairing quake damage. Survivors settle in Ceuta.
