Overview
- A magnitude 6.1 quake struck offshore western Cuba on Monday, June 8, 2026, at a shallow depth of about 10–26 kilometers, according to the USGS.
- The shallow depth helped transmit perceptible shaking across western Cuba, much of Florida and parts of Mexico with reports from Miami, Orlando, Tampa and as far north as Tallahassee.
- Federal agencies including the National Weather Service and the National Tsunami Warning Center assessed there was no tsunami threat for the U.S. East and Gulf coasts and urged continued monitoring.
- Precautionary responses included brief evacuations of some high‑rise and government buildings, temporary theme‑park ride closures and multiple non‑emergency service calls, but no confirmed major damage or fatalities were reported.
- Seismologists say the event is one of the larger instrumentally recorded quakes in the Gulf region since 1950 and may produce aftershocks, so officials are keeping emergency and seismic monitoring active.
