What Mauritania's numbers mean
Mauritania ranks 119th of 187 countries tracked - a country with limited but non-zero seismic activity.
- About 1 M4+ earthquakes strike Mauritania per year on average. See the full country ranking
- 0% of Mauritania's catalogued major earthquakes are shallow (under 70km) - shallow events generally produce stronger surface shaking than deep ones of the same magnitude. How depth affects shaking
- The strongest catalogued event reached M4.6. Compare against neighboring or similarly-ranked countries before drawing conclusions from magnitude alone. Compare strongest earthquakes
