Tectonic setting
The southern coast of Cuba is next to the North American plate. There was a big fault line called the Septentrional-Oriente fault. The North American plate moves west compared to the Gonâve Microplate at 6 to 11 mm per year.[2] This area is where most earthquakes in Cuba happen, with major ones in 1766, 1917,[3] 1932, 1947,[4] 1992,[5] and 2020.
Earthquake
The earthquake had a maximum Modified Mercalli intensity of VIII (Severe). About 2.1 million people felt moderate shaking or stronger. Light shaking was also felt in Jamaica and western Haiti, with reports from Florida and the Cayman Islands. The quake happened along a fault moving sideways, with the fault line running east-west and slanting steeply to the north.[1]
A Mw 5.9 foreshock happened at 15:50 UTC (10:50 EST), also registering an estimated Mercalli intensity of VII (Very Strong).[6]
Impact
There were reports of injuries and collapsed buildings on the island.[7] Landslides were also reported.[8] In Bartolomé Masó, one village had collapsed walls and roofs. In Niquero and Pilón, many buildings partly collapsed. In Santiago de Cuba, a building's roof fell,[9] and the Faro Vargas lighthouse was damaged.[10]
The earthquake struck just four days after Hurricane Rafael,[11] which caused a power outage across the island. This outage was still ongoing during the earthquake, making it hard for officials to give updates.[12] The shaking was felt across eastern Cuba, including big cities like Santiago de Cuba.[13]
