M5.0 earthquake – central Mid-Atlantic Ridge

A magnitude 5.0 earthquake was recorded at 11:42 UTC on June 20, 2025, in the central Mid-Atlantic Ridge. The quake occurred at a shallow depth of 10.0 km (6.2 miles), according to reviewed data from the USGS.

The coordinates place the event along the central section of the Mid-Atlantic Ridge, a vast undersea mountain range which runs the length of the Atlantic Ocean between the Americas, Europe, and Africa. The area is far from major landmasses and population centers, with no nearby cities or settlements.

Critical infrastructure such as ports, airports, highways, or energy facilities are not present in the vicinity owing to the mid-ocean location of the event.

There is no tsunami threat associated with this earthquake, based on its location and available data.

The significance index is 385 (on a scale that runs through 1 000), based on magnitude and estimated impact.

The Mid-Atlantic Ridge is a tectonic plate boundary where the North American and Eurasian plates diverge from the South American and African plates. The region is seismically active, producing frequent moderate to strong underwater earthquakes as the ocean floor gradually spreads.
