A powerful 6.1-magnitude earthquake struck off the northwestern coast of Cuba early Tuesday, sending tremors across large parts of the Caribbean and as far north as southern Florida, according to the United States Geological Survey (USGS).
The earthquake occurred west-northwest of Mantua, Cuba, at a shallow depth estimated between 10 and 26 kilometers beneath the Gulf waters, intensifying the shaking felt across the region. Buildings reportedly shook in Havana, while residents in Miami, Orlando, Tampa, and other Florida cities also reported noticeable tremors. (Reuters)
Authorities confirmed there was no tsunami threat following the earthquake, although emergency services across Cuba and parts of Florida initiated precautionary inspections and public safety assessments. (ABC News)
Tremors Trigger Panic Across Cuba and Florida
Witnesses in Havana described scenes of panic as buildings swayed and residents rushed outdoors. Hotels and residential structures in western Cuba experienced prolonged shaking, though no immediate reports of major structural collapse or fatalities were released by Cuban authorities.

In Florida, emergency management agencies received widespread reports of shaking from residents across Miami-Dade County, Orlando, Tampa, Jacksonville, and surrounding regions. Several office buildings in Miami were temporarily evacuated as a precaution. (FOX 35 Orlando)
The National Weather Service office in Miami stated it had received multiple public reports confirming tremors across southern Florida, emphasizing that no tsunami danger was expected from the seismic event. (NDTV Profit)
One of the Strongest Gulf Region Earthquakes in Modern Records
Seismologists described the earthquake as one of the strongest recorded in the Gulf region in modern history. According to USGS historical data cited by multiple outlets, no earthquake of similar strength had struck within roughly 200 miles of the epicenter since the late 19th century. (Reuters)
Researchers noted the quake was unusual because it occurred within a tectonic plate region rather than directly along a major plate boundary, making such strong seismic events comparatively rare in this part of the Caribbean. (Reuters)
The quake was reportedly detected by seismic monitoring stations more than 1,000 miles away, including instruments in the northeastern United States. (CT Insider)
Transportation and Public Services Briefly Disrupted
The earthquake also caused temporary disruptions to transportation and entertainment facilities in Florida. Some elevated transit services in Miami were briefly suspended while safety checks were carried out. Several attractions at Walt Disney World in Orlando reportedly paused operations as a precautionary measure after guests felt shaking. (AP News)
Authorities in Cuba and the United States continue monitoring the possibility of aftershocks, though officials emphasized that no large-scale emergency had developed as of Tuesday morning. (New York Post)
Emergency Monitoring Continues
Cuban emergency authorities, the USGS, and regional disaster agencies remain on alert as engineers assess infrastructure impacts in western Cuba, where older buildings and fragile infrastructure may face increased risk. (Reuters)
Public safety officials urged residents to remain cautious, avoid damaged structures, and follow emergency guidance in the event of aftershocks.
