The US Pacific Tsunami Warning Center initially issued a warning that there was a threat of tsunami waves reaching 0.3 to 1 meter above tide level for the coasts of Jamaica, Belize, Cuba, Honduras, Mexico and the Cayman Islands. 

But it lifted the alert update about two hours later.

The threat of a tsunami wave had largely passed but minor sea-level fluctuations up to 1 foot were still possible, it said afterwards.

The impact of quakes was hard to predict but the fact that it happened at sea level appeared to have helped,'' according to Don Blakeman, a geophysicist at the National Earthquake Information Center.

"The good news is really that it waved out into the ocean, it would have been a much different story if it had been right in Kingston," he added.

The first, bigger quake rattled several tall buildings in the Cuban capital Havana, which were immediately evacuated.

The earthquake was felt in several provinces including Guantanamo and Santiago de Cuba in the east, Cienfuegos in the centre and Havana in the northwest, the official Cubadebate website reported.

But there were no preliminary reports of damage or injuries.

In Miami, police said  buildings were being evacuated as a precaution after reports of tremors being felt in some areas of the city.
