HAVANA — An earthquake with a preliminary magnitude of 6.8 shook eastern Cuba on Sunday, after weeks of hurricanes and blackouts that have left many on the island reeling.

The epicenter of the quake was located about 25 miles south of Bartolome Maso, Cuba, according to a report by the U.S. Geological Survey.

Rumbling was felt across the eastern stretch of Cuba, including in bigger cities like Santiago de Cuba, as well as Holguin and. Guantanamo. Local media in Jamaica also reported that the island felt the tremors.

There were no immediate reports of major damage or injuries in Cuba.

Residents in Santiago, Cuba’s second-largest city, were left shaken on Sunday. Yolanda Tabío, 76, said that people in the city flocked to the streets and were still nervously sitting in their doorways. She said that she felt at least two aftershocks following the quake, but that among friends and family she hadn’t heard of any damages.

Others reported hearing screams, adding that the quake was strong and stretched on.
