A 5.6-magnitude earthquake struck near the US naval base at Guantanamo, Cuba, on Saturday, but officials said there was no damage reported.
The quake was centred 27 miles (43 km) southwest of Guantanamo and had a depth of 14 miles (22 km), the US Geological Survey reported.
A magnitude-5 quake can cause considerable damage, but Chief Petty Officer Bill Mesta, a spokesperson at the base, said there was none reported.
There was no tsunami warning issued for the region.
The US base in southeastern Cuba was used to transport supplies and personnel to the aid effort after the devastating 7.0-magnitude January 12 quake in Haiti, about 200 miles (320 km) away.
A prison on the base, set up for terrorism suspects after the September 11, 2001, attacks, still houses 188 detainees. President Barack Obama pledged in January 2009 to close the controversial prison within a year, but his efforts to shutter the facility have been hampered by legal and political hurdles. - Reuters
