Caribbean earthquake of 7.7 triggers tsunami warnings

A powerful 7.7-magnitude earthquake has struck in the Caribbean, prompting tsunami warnings for parts of the region, the US Geological Survey (USGS) said on Tuesday.

The quake hit between Jamaica, the Cayman Islands and Cuba at a depth of 10 km (6.2 miles), the USGS said.

Buildings shook and tremors were felt as far away as Miami, but there were no immediate reports of casualties.

Warnings were quickly issued by the Pacific Tsunami Warning Center (PTWC).

The PTWC said “hazardous tsunami waves are possible” for coasts located within 300km (186 miles) of the earthquake’s epicentre.

This includes parts of Belize, Cuba, Honduras, Mexico, the Cayman Islands and Jamaica, it said.

But seismologist Dr Lucy Jones tweeted: “The M7.7 Jamaican quake produced sideways motion on the fault, so the tsunami risk is low.”

The epicentre of the quake, initially reported as magnitude-7.3 before being upgraded, was 125 km north-west of Lucea, Jamaica.
