ATLANTIC OCEAN — A large 6.0 magnitude earthquake struck the Atlantic Ocean east of Antigua and Barbuda at 10:50 AM on Saturday morning May 16, 2026, sending shockwaves across the region but prompting no tsunami threat for the Caribbean or the United States at this time according to initial assessments following the seismic event.
The earthquake epicenter is located in the open Atlantic east of the Lesser Antilles island chain, placing it in the vicinity of Puerto Rico, Hispaniola, and the broader eastern Caribbean region.
6.0 Magnitude Earthquake Strikes Atlantic East of Antigua and Barbuda at 10:50 AM
The 6.0 magnitude earthquake struck at 10:50 AM Saturday morning May 16, originating in the Atlantic Ocean to the east of Antigua and Barbuda in the Lesser Antilles chain of the eastern Caribbean.
A 6.0 magnitude earthquake is classified as a strong seismic event capable of causing significant shaking across a wide area, particularly for island communities and coastal regions situated closest to the epicenter in the eastern Caribbean.
The location of the earthquake in the open Atlantic east of Antigua and Barbuda places it in one of the seismically active zones of the Caribbean basin where tectonic activity regularly occurs along fault systems running through the Lesser Antilles island arc.
No Tsunami Threat Issued for Caribbean or United States Following 6.0 Quake
Following the 6.0 magnitude earthquake east of Antigua and Barbuda, officials have confirmed that no tsunami threat is expected for the Caribbean or the United States at this time, providing significant reassurance to coastal communities across the region that could otherwise be vulnerable to tsunami activity from a seismic event of this magnitude.
The absence of a tsunami threat means that while the earthquake itself was a significant seismic event, the specific characteristics of the fault rupture and the location of the epicenter did not generate the type of seafloor displacement needed to trigger dangerous ocean waves toward Caribbean islands or the United States coastline.
Residents across Antigua and Barbuda, Puerto Rico, Hispaniola, and surrounding eastern Caribbean communities are advised to remain aware of any updates as monitoring of the situation continues following the initial 6.0 magnitude strike.
Monitoring Continues as Aftershocks Remain Possible Following Atlantic Earthquake
Following any significant earthquake event of 6.0 magnitude, aftershocks remain a possibility in the hours and days following the initial seismic event, and residents across the eastern Caribbean region closest to the epicenter should be prepared for potential follow-up shaking.
The broader Caribbean region including Cuba, Hispaniola, Puerto Rico, and the Lesser Antilles island chain falls within the zone where ground shaking from the 6.0 magnitude event may have been felt, though the open ocean location of the epicenter limits the direct impact on populated land areas.
Officials have committed to providing continued updates as the situation is monitored and more detailed information becomes available regarding the full impact of Saturday morning’s large 6.0 magnitude Atlantic earthquake east of Antigua and Barbuda.
