The verdict
Mauritius is moderately seismically active, above the global median, with 135 M4+ earthquakes logged since 2005 and 9 major M6+ events since 1900, the strongest reaching magnitude 6.3.
- 1931
- busiest year (1 major events)
- 13 km
- average recorded event depth
- 100%
- of events are shallow (<70 km, the most damaging kind)
Average catalogued magnitude is 4.7 - most events are moderate M4-5 tremors that are felt but rarely cause damage. On the M4+ activity ladder Turkmenistan sits immediately above at 143 events and Poland sits immediately below at 130.
Where Mauritius sits in the catalog
Rank 70th of 187 tracked countries (62th percentile by M4+ count since 2005). On the M4+ activity ladder Turkmenistan sits immediately above at 143 events and Poland sits immediately below at 130.
- Turkmenistan - next more active (143 M4+)
- Poland - next less active (130 M4+)

What this shows Mauritius's most active year for major earthquakes was 1931 (1 M6+ events). Major-quake counts are irregular, they track the episodic release of tectonic stress, not a smooth trend.
2 of 135 catalogued M4+ events since 2005 reached M6.0 or higher.

About Mauritius's figures
135 M4+ events since 2005 · strongest M6.3 · average M4.7 · 9 M6+ significant events since 1900 · latest M4+ catalog stamp Jul 6, 2026. Computed from the USGS Comprehensive Earthquake Catalog (ComCat). See the methodology and USGS ComCat.

What Mauritius's numbers mean
Mauritius ranks 70th of 187 countries tracked - a country with limited but non-zero seismic activity.
- About 6 M4+ earthquakes strike Mauritius per year on average, though major (M6+) activity is episodic - 1931 was the busiest year on record with 1 significant events. See the full country ranking
- 100% of Mauritius'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 M6.3. Compare against neighboring or similarly-ranked countries before drawing conclusions from magnitude alone. Compare strongest earthquakes
