The 1716 Algiers earthquake was part of a seismic sequence which began in February and ended in May 1716. The largest and most destructive shock occurred on February 3 with an estimated moment magnitude of 7.0. The earthquakes with an epicenter thought to be in the Algiers region had a maximum European macroseismic scale (EMS-98) intensity of IX (Destructive), killing approximately 20,000 people. The earthquake was felt in Catania and Syracuse on the Italian island Sicily.

In an earthquake catalog by Hamdache and other researchers, the moment magnitude was placed at 7.0 Mw with an epicenter location at .
The first shock occurred on the morning of 3 February at 9:45 a.m. local time. It collapsed many poorly-constructed homes in Algiers. Well-constructed buildings including a mosque suffered extensive cracks throughout. Detailed documentation of damage to 204 homes and four mosques or palaces. Algiers was mostly destroyed after the earthquake. At the Dar Aziza, the upper floors experienced a collapse and walls cracked. Many homes up to 3 km away from Algiers were also damaged. The city was once again rocked by a second violent shock assigned IX (Destructive). The aftershock caused more damage and collapsed structures that were intact after the February 3 quake.
