The Calabria region of the Kingdom of Naples sits in a seismically active zone. In early 1783, accumulated tectonic stress along a fault alignment stretching nearly 100 km from the Straits of Messina to southwest of Catanzaro was released in a prolonged sequence of powerful seismic events.
Beginning on 5 February 1783, five earthquakes of estimated magnitude 5.9 or greater struck Calabria over nearly two months. The first two events also produced significant tsunamis. Epicenters formed a clear alignment, with the initial and most destructive shock centered on the plain of Palmi.
The earthquake sequence caused an estimated 32,000 to 50,000 deaths across Calabria. The accompanying tsunamis added to destruction along coastal areas. The disasters prompted notable discussions among Enlightenment thinkers and early efforts by the Kingdom of Naples to plan more systematic regional reconstruction.
