Earthquakes in Mauritius

Mauritius has catalogued 135 M4+ earthquakes since 2005 (ranked 70th of 187 countries), with the strongest reaching magnitude M6.3.

Mauritius ranks 70th of 187 countries by catalogued seismic activity - a country with limited but non-zero seismic activity, averaging about 6 M4+ events a year alongside 9 significant M6+ earthquakes since 1900. Its M6+ record runs from 1931 to 2019, peaking in 1931.

Value

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.

Frequently asked questions

How many earthquakes have occurred in Mauritius?
The USGS catalog records 135 earthquakes of magnitude 4.0 or greater in Mauritius since 2005, an average of about 6 per year. Separately, 9 significant (M6+) earthquakes are catalogued back to 1900.
What was the strongest earthquake in Mauritius?
The strongest catalogued earthquake in Mauritius measured magnitude 6.3. Across the full M4+ catalog the average magnitude is 4.7 - most earthquakes are moderate.
How seismically active is Mauritius?
By catalogued M4+ activity, Mauritius ranks 70th of 187 countries worldwide - a country with limited but non-zero seismic activity. Its busiest year for major (M6+) events was 1931, with 1.
How deep are earthquakes in Mauritius?
Across the 9 major (M6+) events on record, the average depth is 13 km. 100% were shallow (under 70 km), where surface shaking is strongest at a given magnitude.
Where does this data come from?
Every figure is derived from the USGS Comprehensive Earthquake Catalog (ComCat). M4+ counts cover 2005 onward (the period of consistent global completeness); the significant-event series covers M6+ back to 1900. Nothing is modelled or estimated.

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
