A magnitude 6.4 earthquake struck west of Cuba on Monday, prompting reassurances from authorities that Antigua and Barbuda faces no tsunami threat and that no action is required by residents.

According to Antigua News Room, the Pacific Tsunami Warning Center reported that the earthquake occurred at 1800 UTC (2:00 p.m. Eastern Time) in the Cuba region, at a depth of 33 kilometres (20 miles). The epicentre was located at 22.8 degrees north latitude and 85.3 degrees west longitude.

In a tsunami information statement issued shortly after the event, the centre confirmed that based on all available data, there is no significant tsunami threat from the earthquake. The agency did note, however, a very small possibility of localised tsunami waves along coastlines nearest to the epicentre.

Authorities advised that no action is required and indicated that no further statements are expected unless additional information becomes available or conditions change.

The Pacific Tsunami Warning Center issued its statement in support of the UNESCO/IOC Tsunami and Other Coastal Hazards Warning System for the Caribbean and Adjacent Regions.
