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] Destructive earthquakes originating from the Oriente fault occurred in 1766 (MI= 7.6), 1852 (MI = 7.2) and 1932 (Ms = 6.75).
Notable earthquakes in recent Cuban history include the following: Santiago de Cuba[19] Caribbean Sea Intensity= Intensity on the European macroseismic scale (EMS-98), which is somewhat similar to the Modified Mercalli scale (MM)
