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 6.8 magnitude earthquake in the ocean 20 miles off Pilón, a town on the southern coast of the province of Granma in eastern Cuba, shook the region on Sunday minutes before noon, leaving no casualties but at least two children, among them a five-year-old, and two adults injured, Cuban state media said.
