The sight of a waterfall underwater may not sound possible. However, a strange phenomenon was observed in Mauritius, where the underwater waterfall was spotted. But there's more to it than meets the eye.

Mauritius Underwater Waterfall Optical Illusion?

The breathtaking underwater waterfall that may be seen near Le Morne Brabant on Mauritius' southwest coast is an optical illusion, according to Travel Awaits. Sand and silt sediments flow due to strong underwater currents resulting in the impression that they were sucked into a large sewer.

As Big Think puts it, what's going on is more than erosion, the same process through which air and ocean currents wear away coastal regions and break up a solid land mass into tiny, grain-sized pieces.

Sand is abundant throughout Mauritius's coastline, an island produced by volcanic activity, and ocean currents carry it back and forth over the shallow shelves surrounding the island.

There are only deeper, bluer, darker seas where the shallow shelves that make up this underwater plateau stop. And what looks to be an "underwater waterfall" when the ocean currents carry that coastline sand off Mauritius' southern point and into the deep ocean waters is the result of sands sinking through the deep water to the ocean floor.

Due to the highly directed nature of the erosion, the underwater waterfall off the southern coast of Mauritius is genuinely a one-of-a-kind phenomenon. At the extreme tip of the underwater plateau, a horseshoe-shaped chasm leads to the deep ocean depths below.

The famous waterfall scene emerges very strongly when the sand is pushed by ocean currents off of the shallow shelf and into that crevice, demonstrating both the might of rushing water and the fragility of small land masses.

The Canadian side of Niagara Falls and the magnificent Icelandic waterfall Goafoss, sometimes known as the "Waterfall of the Gods," are two of the many horseshoe-shaped waterfalls in existence. Perhaps as a result, whenever we encounter something visually similar, even when it appears underwater, our thoughts automatically assume that we are looking at a waterfall.
