These Weird Underground Objects Might Shake Our Plane

Deep inside the Earth, there are two huge rock blobs that have confused scientists for a long time. They are located far apart from each other, one under the Pacific Ocean and the other under Africa. These strange rock masses are so unique that they even make seismic waves move more slowly. Scientists call them large, low velocity provinces,

but they are just two massive, mysterious rock blobs that are bigger than entire continents and stranger than anything else inside the Earth. They are so dense that they might be pieces from another planet. Until recently, no one knew what they were, where they came from, or why they existed. These mysterious blobs could hold the key to understanding Earth’s deepest forces.

They are powerful enough to shape earthquakes, cause volcanic eruptions, and even influence how life on Earth evolved. Now, we may finally uncover the truth about them. These geological giants are hidden about 1,800 meters below the Earth’s surface. Each one is 10.

Maybe a huge object hit Earth about 4. 5 billion years ago, and this impact created both the moon and these large blobs inside Earth. Scientists think it might have been a planet called Thea, which was about the size of Mars and was somewhere near the asteroid belt. It crashed into Earth long ago.

Some people think it could have been chunks of Earth’s crust from back then. Maybe these chunks were pushed deep into Earth’s interior by tectonic plate movements. A new study says these blobs are big piles of ocean floor crust that have been sinking into Earth for billions of years.

They might have formed from the material that gets pulled down when tectonic plates collide. Over a billion years, pieces of ocean crust could have been swallowed by the mantle. Eventually, they came together to form two large regions deep inside Earth.

But even though both blobs formed the same way, they aren’t exactly the same. There’s a place called the Pacific Ring of Fire

The main question is how do these things keep changing? Scientists believe that big columns of hot rock, called mantle plumes, are coming up from deep inside the Earth. These plumes might be helping move the tectonic plates in the Pacific. If this is true, then these huge underground masses aren’t just sitting still.

They’re almost like living things. They’re always changing and affecting the surface of our planet. But why should we care? Because these strange underground features might be changing Earth’s surface in ways we don’t fully understand. For one, they could influence Earth’s magnetic field.

That’s because they affect how heat flows through the mantle and the core. They might also hold secrets about the history of plate tectonics. Studying them could help us find out when subduction started on Earth—whether it was over 4 billion years ago or much more recently.

These blobs might also be behind volcanic activity. There’s a theory that extremely hot.

That could mean these huge structures might one day break through Earth’s crust, causing massive super volcanic eruptions. These eruptions could last for millions of years. Underneath the Earth’s surface, there are also monsters unlike anything else on the planet—super volcanoes.

They are so huge, so destructive, and so rare that no one has ever seen one erupt. A normal volcanic eruption can be really scary. Lava shoots up into the sky, ash fills the air, and whole cities can be covered in fire and rock. But a super volcano is something completely different.

A super volcano isn’t just bigger—it’s a whole different kind of volcano. When they erupt, they tear the Earth apart, creating huge craters called calderas. Some of these craters are more than 30 miles wide. A regular volcanic eruption might send up a few cubic miles of lava and ash. A super volcano, however, can send up over 240 cubic

The biggest and most terrifying event happened at the end of the Perian period. Almost 90% of all sea creatures and 70% of land animals disappeared completely. Scientists have found about 20 super volcanoes on Earth today.

The most well-known ones are Yellowstone in the United States, Toba in Indonesia, and Topa in New Zealand. The last time Yellowstone erupted was around 2 million years ago. It threw out almost 590 cubic miles of material, which could cover a city like New York.

That was just one of three big eruptions at Yellowstone. The most recent super volcano to erupt was Topa in New Zealand, which happened about 26,500 years ago. But super volcanoes don’t just destroy—they change the whole planet.

About 74,000 years ago, the Toba super volcano erupted in Indonesia. Some scientists think this eruption caused a volcanic winter that lasted for a whole

It can include things like rising magma, the ground swelling, earthquakes under a volcano, changes in gas emissions, and more. The issue is that while we can predict short-term eruptions, the long-term ones are still unknown. Yellowstone last erupted 630,000 years ago. It’s really overdue for another eruption.

But volcanoes don’t work like clocks. Just because one erupted before doesn’t mean it will erupt again for sure. The time between eruptions might be random. Scientists think Yellowstone could erupt again, but it might just be a small lava flow instead of a huge super eruption. Are we ready for a super eruption if it happens?

Probably not. Scientists say we are more prepared for an asteroid than a super volcano. When Hunga Tonga Hunga Haabai erupted in 2022, it blocked communications, caused tsunamis, and filled the sky with ash. And that was only a magnitude 5 eruption.
