Four Indian Ocean Earthquakes in Ten Days: Should Mauritius Worry?
A meteorologist from the Vacoas weather station says the four recent tremors pose no danger to Mauritius, but explains what the data shows.
Four earthquakes were recorded in the Indian Ocean over a period of roughly ten days, prompting concern among residents of Mauritius and the wider region. Avinash Dookhee, a forecaster at the Mauritius Meteorological Services station in Vacoas, a town in the central highlands of the island, says there is no cause for alarm.
According to Dookhee, these tremors are of low magnitude and fall within the range of seismic activity that is considered normal for this part of the ocean. Between November 2025 and November 2026, a total of 68 earthquakes of weak magnitude were recorded in the Indian Ocean region, suggesting that multiple small tremors in a short space of time is not an unusual pattern.
The Mauritius Meteorological Services, based in Vacoas, is the government agency responsible for monitoring weather and seismic activity affecting the island. It operates as part of a broader regional network that tracks tremors across the Indian Ocean, an area that, while less seismically active than the Pacific Rim, still experiences regular low-level activity due to the movement of tectonic plates beneath the ocean floor.
Mauritius itself sits on the African Plate, and the island has no major fault lines running directly beneath it. This geological position means the country is not considered a high-risk earthquake zone, though tremors originating further out in the ocean can occasionally be felt on the island.
The concern that arises when multiple earthquakes occur in quick succession is understandable, particularly given the memory of the 2004 Indian Ocean tsunami, which was triggered by a massive undersea earthquake off the coast of Sumatra and caused widespread destruction across the region. However, that event involved a quake of magnitude 9.1, one of the largest ever recorded. The tremors recently detected near Mauritius are incomparably smaller.
What this means: For residents of Mauritius, there is no immediate risk associated with these four tremors. Low-magnitude earthquakes in the Indian Ocean are recorded dozens of times a year and rarely produce effects that are felt on land. Authorities continue to monitor the situation, and any significant change in seismic patterns would be communicated through official channels. Tourists and expatriates living in Mauritius do not need to take any special precautions at this time.

Frequently Asked Questions
Is Mauritius at risk from earthquakes?β
Mauritius sits on the African Plate and has no major fault lines beneath it, making it a low seismic risk zone. The Mauritius Meteorological Services in Vacoas monitors regional tremors and says the recent low-magnitude earthquakes in the Indian Ocean pose no danger to the island.
How many earthquakes were recorded near Mauritius recently?β
Four earthquakes were recorded in the Indian Ocean over approximately ten days. More broadly, 68 low-magnitude tremors were detected in the region between November 2025 and November 2026, indicating this level of activity is within normal range.
Who monitors earthquake and weather alerts in Mauritius?β
The Mauritius Meteorological Services, headquartered in Vacoas in the central highlands of Mauritius, is the government body responsible for tracking weather and seismic events. It issues public alerts when any risk to the island is identified.
