How an Underwater Waterfall Formed on Mauritius Island

What is an underwater waterfall and how does it work?

An underwater waterfall is a mesmerizing optical illusion created by sand and silt runoff from the island’s rivers that flows down the underwater slopes, resembling a waterfall. The force of ocean currents pushes the sediment down, creating the illusion of water cascading below the surface.

Understanding the Phenomenon of Underwater Waterfalls

To truly understand the phenomenon of underwater waterfalls, it is important to grasp the concept of an optical illusion. An optical illusion occurs when our eyes are tricked into perceiving something that is not actually there. In the case of the underwater waterfall, the illusion is created by the interaction of various factors, including the submarine plateau, ocean currents, and the unique geography of Mauritius Island.

An underwater waterfall is not actually a waterfall in the traditional sense. Instead, it is an optical illusion created by the movement of sand and silt deposits off the coast of Mauritius Island. The illusion is formed by the interaction of the submarine plateau, ocean currents, and the steep slope leading from the shore to the ocean floor. As sand and silt slide down this slope, they give the appearance of a cascading waterfall. According to some of the best travel guides, one of the most famous locations to witness this optical illusion is off the coast of the Le Morne Peninsula, a UNESCO World Heritage Site. The underwater waterfall in this area is a breathtaking sight that attracts visitors from around the world.
