A magnitude 5.0 earthquake struck the southern Mid-Atlantic Ridge at approximately 10 kilometers (6 miles) depth, according to the U.S. Geological Survey. The Mid-Atlantic Ridge is an underwater mountain range that runs down the center of the Atlantic Ocean, marking where the North American and Eurasian plates (in the north) and South American and African plates (in the south) are slowly spreading apart.
Because this earthquake occurred in the open ocean far from populated coastlines, impacts to populated areas are expected to be minimal. However, sensitive seismic instruments across the Atlantic basin and beyond will have detected the event clearly. The depth of 10 km is relatively shallow for underwater earthquakes, which can sometimes trigger minor tsunami activity—though initial assessments indicate no significant wave threat.
What You Should Know
Who is affected: Coastal communities along the Atlantic, particularly in West Africa, the Caribbean, and parts of Europe and North America, should remain aware of ocean conditions. Mariners in the mid-Atlantic should monitor local maritime alerts.
What to watch: Keep an eye on official NOAA and USGS updates if you live near the Atlantic coast. While this magnitude 5.0 event is moderate, it serves as a reminder to have a tsunami preparedness plan if you’re in a coastal zone.
Preparedness pointers: If you’re coastal, know your evacuation routes and the location of higher ground. Download weather alert apps that include tsunami warnings. For those inland, earthquakes of this size reinforce the value of having an emergency kit with water, first aid supplies, and a battery-powered radio—useful for any natural disaster.
