Strong magnitude 6.1 earthquake strikes Cuba's northwest coast

Historical Rarity

According to the USGS, it was the strongest earthquake since 1880 within a 322-kilometer radius of the epicenter. At that time, a magnitude 6.0 quake had struck near San Cristóbal. The current event is therefore considered historically exceptional for this part of the Caribbean.

There are no reports so far of major damage or casualties. However, ongoing power outages in the region hampered communication, meaning a final assessment of the situation is likely to take some time. Yusmila Hernandez from Pinar del Río in western Cuba also reported: "It felt strong. I had never felt anything like that."

Effects in Mexico and the USA

The quake was felt in the Mexican tourist centers of Cancun and Tulum, as well as on the Mexican Yucatán Peninsula. In Cancun, numerous people left buildings out of fear. Residents in the U.S. state of Florida also registered the tremors.

Concern in the affected region nevertheless remains high. Authorities and rescue services in Cuba inspected buildings and infrastructure, while power supply across large parts of western Cuba remained disrupted. According to experts, the combination of a rare intraplate earthquake and the already fragile building stock increases the likelihood of secondary damage.

Challenges in Assessing the Situation

Earle further explained that while earthquakes within a tectonic plate occur less frequently, they can be perceived over comparatively large areas. The shallow depth of 26 kilometers contributed to the fact that the quake was felt in several countries simultaneously.

Authorities in Cuba, Mexico, and the USA called on the population to remain calm and to be prepared for possible aftershocks. Although no major damage has been confirmed so far, the situation remained tense given Cuba's already strained supply situation.

Experts stress that every strong quake in this region must be carefully examined, as the tectonic conditions in the Caribbean Sea are complex. The USGS announced that it would continue to monitor the readings and possible aftershocks in the coming days.
