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.

Observed impact record

What ComCat observed after earthquakes in Mauritius

USGS recorded Modified Mercalli Intensity (MMI) for 1 events in this catalogued record; their average observed intensity was MMI 0.0. These are only events with an observation, not an estimate of future shaking or a safety rating.

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.
