With a staggering 3.500 meters of drop, the largest waterfall on Earth is submerged between Iceland and Greenland, moving more water than the Amazon River and impacting the global climate.
When you think of waterfalls, you imagine the majestic Niagara Falls or the impressive Angel Falls, right? But what if I told you that the largest waterfall on Earth is not on dry land, but submerged in the depths of the ocean? Yes, the Denmark Strait Falls redefines everything we know about the power of water.
This hidden wonder is so grandiose that it dwarfs any waterfall on Earth. Let’s dive into its history and discover why this underwater giant is so important to our planet.
What are waterfalls?
Waterfalls that we see on dry land form when water flows down a steep drop, such as a cliff or overhang. This continuous flow carves the rocks, creating breathtaking landscapes. In addition to their beauty, waterfalls support unique ecosystems by providing moisture and creating ideal environments for specific plants and animals.

Underwater waterfalls, while invisible to the naked eye, are no less spectacular. They don’t “fall” in the same way as land-based waterfalls. Instead, they are formed by currents of water that move due to differences in density, temperature, and salinity. It’s as if the ocean has its own secret waterfalls.
The Denmark Strait Waterfall: The Hidden Giant
Located between Iceland and Greenland, this underwater waterfall drops an impressive 3.500 feet — more than three times the height of Angel Falls, the tallest waterfall on land. Its width of about 480 miles makes it a colossal force on the ocean floor.
The Denmark Strait waterfall is formed when the cold waters of the Nordic seas meet the warmer waters of the Atlantic. The difference in density between these waters creates a powerful flow that transports colossal volumes of water every second. It is a phenomenon that occurs silently, but with a gigantic impact.
The origin and importance of the largest waterfall on Earth
This underwater waterfall is a relic of the last Ice Age, which formed between 17.500 and 11.500 years ago. As glaciers carved the landscape, ocean currents shaped the unique structure we see today. This natural wonder remains active thanks to the ongoing interaction between currents and geological conditions.
In addition to its magnitude, the Denmark Strait cataract plays a crucial role in the thermohaline circulation — the “engine” that regulates global ocean currents. This system distributes heat, nutrients and energy, affecting climate, sea levels and even marine life across the planet.

While waterfalls like Niagara are impressive due to their noise and visible force, the Denmark Strait Falls operate silently, hidden from our eyes. With 3,2 million cubic meters of water flowing every second, it far exceeds the volume of the Amazon River, but its grandeur can only be seen with advanced instruments.
This underwater waterfall is a reminder that not everything powerful needs to be visible. Just as the invisible forces of wind and gravity shape our world, this underwater giant works behind the scenes, sustaining life and balancing the planet.
The largest waterfall on Earth, hidden in the Denmark Strait, shows us that the planet is full of wonders beyond our imagination. Although we can’t see it, its presence influences life across the globe, regulating currents and shaping climates. It’s a powerful reminder that the most important forces aren’t always in plain sight—sometimes they’re hidden deep beneath the ocean.
