If you thought the Earth was fully mapped out by now, then you would be wrong. Scientists have just uncovered what could be a massive new island, and we’re not talking about some tiny sandbank. This thing is the size of Spain and has been hiding 1,200km off the coast of Brazil. The thing is, Brazil is already trying to claim it as part of its national territory, let’s break it down.
So, Where Did This Island Come From?

This isn’t some tropical paradise that just popped up overnight. The Rio Grande Rise (RGR), as scientists are calling it, is actually the result of a giant volcanic eruption that covered the ocean floor in basalt lava millions of years ago. Researchers at the University of São Paulo (USP, Brazil) have spent over a decade studying this place, and now, they believe it might be part of a lost continent.
Scientists Have Been Watching This for Years

Geologists have been analyzing Rio Grande Rise for over 10 years, and thanks to new research, they’ve confirmed that its surface has been above sea level in the past. That means at some point in history, this was an actual island. And now, Brazil wants to officially extend its borders to claim it as part of its continental shelf.
The Science Behind the Discovery

Professor Luigi Jovane, who has been leading the study, explained that the clay formations on RGR were created between 30 and 40 million years ago, following the region’s last major volcanic activity 45 million years ago. The entire landmass formed due to tropical conditions, which played a role in shaping the ecosystem. Scientists now believe this region is critical to understanding oceanic ecosystems and climate history.
So, Who Owns It?

Until recently, Rio Grande Rise was considered international waters, monitored by the United Nations International Seabed Authority (aka, no man’s land). But Brazil is now trying to stake its claim to extend its maritime borders beyond the 200-mile zone, which would give it full control over the mineral-rich island. And, let’s be honest, the minerals are probably what they’re after.
What’s So Valuable About Rio Grande Rise?

Scientists have found evidence that this area could be loaded with rare minerals, including cobalt, nickel, and manganese, all of which are super valuable for tech industries. These minerals are used in batteries, electronics, and renewable energy storage. If Brazil successfully claims the territory, they’ll gain exclusive rights to these resources, making it a huge economic win.
Environmentalists Are Sounding the Alarm

As exciting as this discovery is, not everyone is thrilled. Scientists are worried that if deep-sea mining starts, it could destroy entire ecosystems before we even fully understand what’s there. Since this island is still mostly untouched, conservationists are pushing for it to be protected rather than exploited.
A Lost Continent? Some Experts Think So

There’s a theory floating around that Rio Grande Rise could be part of an ancient, submerged continent. Some scientists believe that millions of years ago, this landmass was connected to South America, before slowly sinking below the waves. If true, that would make this one of the biggest geological discoveries of the century.
What Happens Next?

Now that Brazil has officially staked its claim on the Rio Grande Rise, a few scenarios could play out. The United Nations could approve Brazil’s request, granting it full sovereignty over the island and its resources. But it’s not that simple, other nations might contest the claim, triggering a diplomatic tug-of-war over who truly owns the land. If no agreement is reached, the island could remain in international waters, leaving its future tied up in legal battles and ongoing debates over conservation, development, and mineral rights for years to come.
The Future of Rio Grande Rise

Whether it becomes part of Brazil or remains a protected marine reserve, Rio Grande Rise is now on the global map. Expect to hear a lot more about deep-sea exploration, mineral rights, and environmental fights over the next few years. Because once a landmass this big is discovered, everyone wants a piece of it.
Why This Matters

A massive island the size of Spain has been discovered off the coast of Brazil, and the country is already making moves to claim it as part of its territory. Citing geological history and territorial expansion laws, Brazil argues it has rightful ownership. Scientists believe the island could hold valuable minerals, but they’re also warning against deep-sea mining, as some think this landmass may be part of a lost continent.
Could More Islands Like This Exist?

If Rio Grande Rise has been hiding for millions of years, who’s to say there aren’t other lost continents waiting to be discovered? With better deep-sea technology, we could be on the brink of a new age of geological exploration.
Who Will Win the Battle for RGR?

So, is Rio Grande Rise about to become Brazil’s newest territory? Or will international courts step in and keep it neutral? One thing’s for sure, this is just the beginning of a major territorial battle. Whether for science, politics, or profit, everyone wants a claim. Who will win? Stay tuned.
