M5.1 Shallow Earthquake Recorded Near central Mid-Atlantic Ridge

USGS Week reports M5.1 near central Mid-Atlantic Ridge, with a 10.0 km catalog depth.

The event began at Fri, 04 Sep 2026 23:38:40 GMT. USGS Week reports magnitude 5.1, 10.0 km catalog depth, and coordinates 9.467, -40.847.

The catalog location label is central Mid-Atlantic Ridge; no separate nearest-city field was supplied with this solution. By catalog depth, this is a shallow event. The magnitude-derived energy estimate is 2.82e+12 joules, or about 674 tons of TNT equivalent; that calculation describes source energy, not local damage.

The current catalog entry does not include a public felt-report count. Other attached observation fields include catalog significance score 400. No official casualty or damage statement is attached to the normalized event evidence.

The USGS Week catalog currently marks the solution as reviewed. No station-count, phase-count, residual, gap, or uncertainty fields were supplied in the normalized record. 1 alternate network solution is retained for comparison.

The provider record does not carry a tsunami flag at publication time. Magnitude, depth, and location can change as monitoring networks add observations and review the solution.
