6.1‑Magnitude Earthquake Off Cuba Hits Gulf, Shakes Florida

On Monday, June 8, a 6.1‑ magnitude earthquake struck the southern Gulf of Mexico, 64.9 miles west‑northwest of Mantua, Cuba. The U.S. Geological Survey (USGS) recorded the event at 2 p.m. Eastern time, marking one of the strongest tremors recorded in the Gulf in the past century.

The quake produced weak shaking (Modified Mercalli Intensity 3) over a broad area. Residents in Miami, Tampa, and other parts of Florida reported noticeable vibrations. In Miami, several high‑rise buildings were evacuated, and the Dadeland Metrorail Station was temporarily closed. According to city officials, four calls were made that appeared to be related to building movements, but all were cleared and no injuries were reported.

Emergency services in Florida were notified of the seismic event. The Miami Fire‑Rescue reported that calls for service were made from multiple neighborhoods, yet no significant damage or injuries were observed. City statements emphasized that the situation remained stable and that teams were monitoring for any subsequent aftershocks.

Officials from the National Weather Service and the National Tsunami Center confirmed there was no tsunami threat associated with the earthquake. This assessment is consistent with the depth and distance of the seismic activity.

While the tremor was felt across Florida, it was also reported in areas of Mexico. A user in Playa Del Carmen noted that the ground had been shaking for about a minute, describing it as “worse than the two earthquakes I’ve experienced in LA.”

Seismologists are continuing to review data from the event. The USGS may revise the reported magnitude based on additional measurements, and updated intensity maps will be released as aftershocks are documented.

For residents in the Gulf region, the 6.1‑ magnitude quake serves as a reminder of the persistent seismic activity under the Atlantic Ocean. While the event did not cause damage, it highlighted the importance of preparedness and the need for ongoing monitoring by geological and emergency agencies.
