Buildings shook in Havana, earthquake of 6.1 magnitude occurred off the coast of Cuba
A powerful earthquake of magnitude 6.1 struck offshore near Cuba, sending noticeable tremors through the capital, Havana. According to early reports, the quake was felt strongly across the region, but there were no immediate reports of structural damage or casualties.
What happened
The earthquake occurred beneath the ocean, which initially raised concerns about a possible tsunami. Authorities, however, quickly confirmed that no tsunami warning or watch had been issued in connection with the event. Residents in several Havana neighbourhoods reported feeling the shaking, and some moved outdoors as a precaution.
Why offshore quakes raise tsunami concerns
Undersea earthquakes can, in some cases, displace large volumes of water and trigger tsunamis — which is why offshore events are assessed quickly for that risk. Many quakes, though, do not generate one; the outcome depends on factors like depth, magnitude and the type of fault movement. In this case, officials determined no tsunami threat existed.
Understanding a magnitude 6.1 quake
A 6.1 magnitude earthquake is considered moderate-to-strong and can be felt over a wide area. Whether it causes damage depends heavily on depth, distance from populated areas and local building standards — which is why a strongly felt quake can still result in little or no damage.
What authorities advised
Seismologists continued to monitor the situation given the offshore origin, and the Cuban government urged the public to stay informed through official channels. Emergency services reported no incidents caused by the quake.
