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."

Two strong earthquakes struck off Cuba’s coast Sunday, damaging homes and infrastructure and triggering landslides just as the country was in the middle of cleanup efforts following the landfall of major Hurricane Rafael last week.
