Overview
- The United States Geological Survey and the European-Mediterranean Seismological Centre both recorded the event as magnitude 6.7 with a depth of 10 kilometers.
- Officials issued a USGS Green alert, which signals a low likelihood of shaking-related fatalities and major economic losses.
- Authorities and the Pacific Tsunami Warning Center reported no tsunami threat from the quake.
- The epicenter was located roughly 1,000–1,200 kilometers offshore from small towns on Ascension Island and the coast of Sierra Leone, limiting expected onshore shaking and damage.
- The Mid‑Atlantic Ridge is a spreading plate boundary where shallow quakes are common, so scientists say this event fits regional seismic patterns and is unlikely to change local risk levels.
