A strong earthquake with a preliminary magnitude of 6.6 struck on Wednesday night in the Caribbean Sea, just off the Panama-Colombia border, the US Geological Survey said.

There was no immediate word on whether were any injuries or damage in the nearby areas, which are not densely populated.

The USGS said the quake was centered about 41 km northeast of Puerto Obaldia, Panama. The epicentre was at a depth of 10 km. An aftershock with a magnitude of 4.9 followed about 10 minutes after the original quake.

Panama's civil defence agency said via Twitter that the earthquake was felt in the provinces of Darien, Panama, Guna Yala and West Panama. “There is no report of effects,” it said. A short time later, it said Panama's National Emergency Operations Centre had ruled out the possibility of a tsunami.

The temblor was felt in some parts of Panama's capital, but not in others. Residents in the Colombian cities of Medellin and Cali also felt shaking.

The region shaken is home to the Darien Gap, a sparsely settled area of dense jungle that is a primary land route for migrants heading north out of South America. Hundreds of thousands of migrants have passed through in recent years.
