A magnitude 6.4 earthquake struck west of Cuba on Monday, but authorities say there is no tsunami threat to Antigua and Barbuda and no action is required.

The Pacific Tsunami Warning Center said the earthquake occurred at 1800 UTC (2 p.m. Eastern Time) in the Cuba region at a depth of 33 kilometres (20 miles). The quake’s 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 said that based on all available data, there is no significant tsunami threat from the earthquake. However, it noted there is a very small possibility of tsunami waves along coastlines nearest to the epicentre.

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

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