New Delhi: A strong offshore earthquake struck northwest of Cuba on Monday, sending tremors across the Caribbean, the Gulf of Mexico and parts of the southeastern United States in a rare seismic event that was widely felt across multiple countries.
Authorities confirmed that the quake measured magnitude 6.1, according to the United States Geological Survey (USGS), and originated at a shallow depth of about 26 kilometers. The epicentre was located approximately 104 kilometers west-northwest of Mantua in western Cuba.
Rare and Unusual Seismic Activity
Seismologists described the earthquake as unusual due to its location within a tectonic plate rather than along a major plate boundary. Experts noted that no quake of comparable strength had been recorded within roughly 320 kilometers of the region since the late 19th century, highlighting its rarity.
Tremors Shake Western Cuba
The quake was strongly felt across western Cuba, including Havana and Pinar del Río. Residents reported buildings swaying and people rushing into the streets as panic spread. Many said they had never experienced such intense shaking before.
Concerns were heightened by existing infrastructure vulnerabilities and ongoing power outages in parts of the country, which made communication and emergency response more difficult. Authorities carried out rapid assessments, though no major structural damage or casualties were immediately reported.
Effects Reached US and Mexico
The tremors were also felt across southern Florida, including Miami, Fort Lauderdale and areas further north. Several buildings were evacuated as a precaution, and some transport services were briefly halted for safety inspections. Despite the strong sensation of shaking, officials confirmed there were no reports of injuries or significant damage.
In Mexico’s Yucatán Peninsula, including Cancun, Playa del Carmen and Tulum, hotels, offices and commercial buildings were briefly evacuated as residents experienced noticeable tremors. Local authorities activated emergency protocols, but no major damage was recorded.
No Tsunami Threat, Aftershocks Possible
Experts confirmed that no tsunami warning was issued following the quake. However, they warned that western Cuba could experience aftershocks, though these are expected to be weaker and unlikely to significantly affect distant regions.
Second Quake in Iran
In a separate event, a magnitude 5.0 earthquake struck southern Iran near Hormozgan province. Authorities reported no immediate casualties or damage. Iran remains one of the world’s most seismically active regions due to its complex fault systems.
