M5.0 earthquake – central Mid-Atlantic Ridge

An M5.0 earthquake struck the central Mid-Atlantic Ridge at 14:59 UTC on June 19, 2025. The quake occurred at a depth of 10.0 km (6.2 miles), based on reviewed data from USGS.

The location is within the central segment of the Mid-Atlantic Ridge, a submarine mountain range in the Atlantic Ocean. There are no known cities, islands, or population centers near the epicenter at coordinates 28.8°S, 0.9°E.

Given the remote oceanic setting, there is no major critical infrastructure such as ports, airports, highways, or populated settlements in the immediate area.

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, felt reports, and estimated impact.

This area is seismically active due to the divergent tectonic boundary between the Eurasian, North American, South American, and African plates along the Mid-Atlantic Ridge, where frequent moderate earthquakes occur as the plates move apart.
