An earthquake with a preliminary magnitude of 6.8 has shaken eastern Cuba after weeks of hurricanes and blackouts that have left many on the island reeling.

An impactful 6.8 earthquake struck Cuba on Sunday amid a grueling recovery from recent power failures and damaging hurricane activity, officials said. According to the United States Geological Survey, the earthquake "occurred as the result of predominantly strike-slip faulting at shallow depth near within the Septentrional-Oriente Fault Zone."

A pair of strong earthquakes has struck off the southern coast of Cuba, inflicting damage and causing landslides.

Two powerful earthquakes rocked southern Cuba in quick succession on Sunday, US geologists said, just days after the island was struck by a hurricane that knocked out power nationwide.

After weeks of hurricanes and blackouts have left many in Cuba reeling, an earthquake has left people shaken as rumbling was felt across the eastern stretch of the island, including in bigger cities like Santiago de Cuba,
