Cuba is located in an area with several active fault systems which produce on average about 2000 seismic events each year.[1] While most registered seismic events pass unnoticed, the island has been struck by a number of destructive earthquakes over the past four centuries, including several major quakes with a magnitude of 7.0 or above.
Approximately 70% of seismic activity in Cuba emanates from the Oriente fault zone, located in the Bartlett-Cayman fault system which runs along the south-eastern coast of Cuba and marks the tectonic boundary between the North American Plate and the Caribbean Plate.[2] The 12 currently active faults in Cuba also include the Cauto-Nipe, Cochinos and Nortecubana faults.[2] Destructive earthquakes originating from the Oriente fault occurred in 1766 (MI= 7.6), 1852 (MI = 7.2) and 1932 (Ms = 6.75).[3] Some studies suggested there is a high probability the Oriente fault would produce a magnitude 7 earthquake,[4] this happening in January 2020, with a magnitude of 7.7, the highest registered in this country's history.
Notable earthquakes in recent Cuban history include the following:
