Powerful 7.7 earthquake strikes in Caribbean between Cuba and Jamaica

News from Cuba | Tuesday, 28 January 2020

The USGS initially estimated the quake's magnitude at 7.3 before upgrading it to 7.7. The ensuing aftershocks so far have topped out at a magnitude 6.1.

The Pacific Tsunami Warning Center said any tsunami threats from the earthquake have passed and no other ones are foreseen.

There have been no immediate reports of damage or injuries. However, the earthquake caused very strong to severe shaking in portions of far western Jamaica, capable of moderate to heavy damage, the USGS said.

It also said moderate shaking was felt on Grand Cayman Island, while light shaking was reported on the Yucatan Peninsula in Mexico. Other affected countries include the Bahamas, Haiti and Honduras.

Gov. Carlos Joaquín González of Mexico’s Quintana Roo, which is home to Cancun, Tulum and other popular Caribbean beach resorts, said the earthquake was felt in multiple parts of the state. In total, five states in Mexico felt the tremor, the country's seismological service reported.

The quake was also felt as far away as South Florida, and buildings in Miami were evacuated as a precaution.

Stenette Davis, a psychiatrist at a Cayman Islands hospital, said she saw manhole covers blown off by the force of the quake, and sewage exploding into the street, but no more serious damage.

Claude Diedrick, 71, who owns a fencing business in Montego Bay, said the shaking felt "like I was on a bridge and like there were two or three heavy trucks and the bridge was rocking, but there were no trucks.”

The quake was also felt strongly in the coastal city of Santiago, in the eastern part of Cuba.

“We were all sitting and we felt the chairs move,” said Belkis Guerrero, who works in a Catholic cultural center in Santiago. “We heard the noise of everything moving around.”

Enrique Arango Arias, head of Cuba’s National Seismological Service, told state media no serious damage or injuries have been reported.

This is the fourth magnitude 7 or greater quake in the Caribbean since 2000, according to AccuWeather meteorologist Jesse Ferrell.

The quake appears to be on a fault boundary between the North American and Caribbean plates, according to seismologist Lucy Jones.

The last month has been an extremely active period for earthquakes in the Caribbean. The southern part of Puerto Rico was hit by a sequence of quakes that began on Dec. 28 with a magnitude 4.7 shaker and was followed Jan. 7 by a magnitude 6.4 aftershock, then a 5.2 on Jan. 15.

The USGS said the sequence has produced more than 300 quakes bigger than magnitude 3, which can be felt by humans.
