A powerful earthquake registered by the USGS as M7.7 hit off the southern coast of Cuba at 19:10 UTC (14:10 LT) on January 28, 2020. The agency is reporting a depth of 10 km (6.2 miles). EMSC is reporting the same magnitude and depth.
The epicenter was located 125.9 km (78.2 miles) NNW of Lucea (population 6 289), Jamaica, 139.1 km (86.5 miles) NW of Montego Bay (82 867), Jamaica, and 140.3 km (87.1 miles) WSW of Niquero (population 18 771), Cuba.
There are no people living within 100 km (62 miles).
1 000 people are estimated to have felt very strong shaking, 505 000 strong, 5 476 000 moderate and 13 962 000 light.
Based on all available data, hazardous tsunami waves are forecast for some coasts, PTWC said at 19:46 UTC.
Tsunami waves reaching 0.3 to 1 m (1 - 3.3 feet) above tide level are possible for some coasts of Belize, Cuba, Honduras, Mexico, Cayman Islands, and Jamaica.
Actual amplitudes at the coast may vary from forecast amplitudes due to uncertainties in the forecast and local features. In particular maximum tsunami amplitudes on atolls or small islands and at locations with fringing or barrier reefs will likely be much smaller than the forecast indicates.
Based on all available data, the tsunami threat from this earthquake has passed and there is no further threat, PTWC reported at 20:43 UTC.
The USGS issued a green alert for shaking-related fatalities. There is a low likelihood of casualties.
A yellow alert was issued for economic losses. Some damage is possible and the impact should be relatively localized. Estimated economic losses are less than 1% of GDP of Cuba. Past events with this alert level have required a local or regional level response.
Overall, the population in this region resides in structures that are resistant to earthquake shaking, though vulnerable structures exist. The predominant vulnerable building types are unreinforced brick masonry and reinforced masonry construction.

The quake was followed by M6.1 at 21:55 UTC, 57.7 km (35.8 miles) SE of East End, Cayman Islands - USGS, depth 10 km (6.2 miles). EMSC is reporting the same magnitude and depth.
There are about 54 000 people living within 100 km (62 miles).
The USGS issued a green alert for shaking-related fatalities and economic losses. There is a low likelihood of casualties and damage.
61 000 people are estimated to have felt light shaking.
Another fascinating video from the #earthquake in the Jamaica/Cuba/Cayman region. Thankfully no fatalities have been reported and the Tsunami warning has been dropped. Sorry, I don’t have the video credit name. pic.twitter.com/krM8pV41ew— Scott Estabrooks (@scotestabrooks) January 29, 2020
Cayman earthquake from my house during the @realvision Exec Team meeting. The earth shook (as did the chandelier!). 7.8 on the Richter Scale between Jamaica and Little Cayman #caymanearthquake #caymanislands #caymanislandsearthquake#earthquake pic.twitter.com/3wF94sslyu— Raoul Pal (@RaoulGMI) January 29, 2020
Better Safe Than Sorry! Folks at a resort in the #CaymanIslands headed to higher ground in case of a #tsunami after the major #earthquake today. #Caribbeanquake— WeatherNation (@WeatherNation) January 29, 2020
