The essentials
No tsunami threat issued after Cuba's 6.1 magnitude earthquake despite regional shaking.
Authorities have confirmed that no tsunami warning was issued following the 6.1 magnitude earthquake that struck off western Cuba. Despite the earthquake's strength and wide geographic reach—with shaking felt in Florida and Mexico—the seismic activity did not generate conditions warranting a tsunami alert.
The absence of a tsunami warning reflects the depth and location of the earthquake relative to ocean basins. Coastal communities that experienced the initial shaking faced no secondary hazards from tsunami waves, allowing populations to return to normal activities once ground motion subsided.

Earthquake magnitude insufficient for tsunami generation
The 6.1 magnitude earthquake and its offshore location did not create the conditions necessary for significant tsunami generation. Seismic parameters—including depth, magnitude, and fault orientation—determined that no tsunami warning was warranted, protecting coastal infrastructure from unnecessary precautionary measures while maintaining public safety protocols.
Widespread shaking confirmed with no secondary marine threat
Though the earthquake was felt across Florida and Mexico, the geological characteristics of the event meant coastal populations faced only the primary seismic hazard. The lack of a tsunami warning distinguished this event as primarily a ground-motion event rather than a compound seismic-marine disaster.
