Has the eighth wonder of the world been rediscovered after 131 years?

The mythical New Zealand monument that was believed destroyed by the volcanic eruption of Mount Tarawera in 1886, the White and Pink Terraces may not be destroyed. The terraces were on the edges of Lake Rotomahana until Mount Tarawera erupted on June 10, 1886, causing a cataclysm equivalent to the one that originated the most powerful bomb of all time, that of the Tsar.

This is the new mineral that has been found inside a diamond
Called goldschmidtita in honor of Victor Moritz Goldschmidt, the founder of modern geochemistry, a new mineral has been discovered inside a diamond unearthed from a mine in South Africa. The finding was made by Nicole Meyer, a graduate student at the Diamond Exploration Research and Training School of the University of Alberta (Canada) and the details have been published in American Mineralogist.
There are tracks of Gran Adria, a lost continent that is below the mountains of the Mediterranean
There are tracks of Gran Adria, a lost continent that is below the mountains of the Mediterranean
Geologists from several countries, when investigating all mountain ranges from Spain to Iran in detail for ten years, have found evidence of the existence of the lost continent of Grand Adria, a piece of continental crust the size of Greenland, which once separated from the North Africa sank in the mantle of the earth beneath southern Europe.
Identified diamonds as old as the Moon in the Earth's mantle
Identified diamonds as old as the Moon in the Earth's mantle
Hidden at 410 kilometers in the Earth's mantle, somewhere between the crust and the core, it is suspected that there is a reservoir of diamonds as old as our natural satellite, according to a new study carried out by the Australian National University. These diamonds would be in a large reserve of relatively intact rock since the formation of the planet, safe from the violent geological activity and extraterrestrial impacts that hit Earth.
Our beaches and much of our technology had the same creator: plate tectonics
Our beaches and much of our technology had the same creator: plate tectonics
Earthquakes, volcanoes or mountain formations depend on plate tectonics. The tectonic plates that are part of the Earth's surface and the landslides that are observed between them in their movement over the fluid earth mantle, their directions and interactions. Also thanks to plate tectonics we have a material that did not exist on the primitive Earth, because it was literally created by it and that we currently use in microchips.
It is the first time we have found real evidence of extraterrestrial carbon in terrestrial rocks
It is the first time we have found real evidence of extraterrestrial carbon in terrestrial rocks
A study by the Center for Molecular Biophysics of CNRS, the official research center of France has shown extraterrestrial carbon in terrestrial rocks. Specifically, organic matter from outside the Earth has been discovered preserved in a thin layer of sedimentary rock 3 years ago.
These glass spheres found in the sand on the beach are atomic debris from Hiroshima
These glass spheres found in the sand on the beach are atomic debris from Hiroshima
On the beach of the Japanese peninsula of Motoujina, tiny glassy spheres and other strange particles have been found that can be defined as atomic debris from Hiroshima, which is very close to here, as a result of the US attack with an atomic bomb in 1945. Based on the volume of vitreous residues found in the sands of the beach, Wannier and his colleagues estimated that a square kilometer of beach sand in the area, collected from its surface at a depth of approximately 10.16 centimeters, would contain approximately between 2.

Towards the end of December 2014, NASA researchers realized that the satellites were detecting a volcanic column near Tonga, in the Pacific Ocean. By the end of January 2015, the eruption was over and new lands stretched between two older islands, called Hunga Tonga and Hunga Ha'apai.
The 1.5 km tsunami that swept the world at the time of the dinosaurs
The 1.5 km tsunami that swept the world at the time of the dinosaurs
Scientists led by Molly Range, from the University of Michigan Ann Arbor, have conducted simulations of the consequences of the impact of the Chicxulub asteroid, which killed dinosaurs 66 million years ago. This model suggests that the impact of the asteroid not only had important effects on the global atmosphere and biosphere, but also created a tsunami that had global effects.
This was the largest volcanic eruption in history.
This was the largest volcanic eruption in history.
The eruption of the Tambora volcano, on the Indonesian island of Sumbawa, in 1815, was the most powerful ever recorded, as we have already explained. However, we can establish the power of the volcano also with other parameters. For example, calculating what has been the biggest effusive eruption, that is, when lava flows flow in a volcano instead of violently erupting.
This is one of the most recent islands that has formed and is barely 50 years old.
This is one of the most recent islands that has formed and is barely 50 years old.
The islands make you feel, as the name implies, isolated from the rest of the world. Especially if you land on the most remote island on Earth, 2,500 kilometers from any inhabited site. But the islands can also be so recent that, in addition, you can feel that you are treading a virgin terrain, typical of another planet.

What is the largest iceberg on record?
Some of the figures of fresh water that we can find in the longest and largest rivers in the world are hard to imagine, like these two that dispute the first place, but if we look at frozen fresh water, then these figures become derisory The largest mass of fresh water we know, for example, is the Antarctic polar cap, which contains approximately 70% of all the fresh water on the planet.
These were the biggest waterfalls ever on Earth
These were the biggest waterfalls ever on Earth
Although Niagara Falls immediately come to mind when we think of large waterfalls, there are 500 in front of them. There are even much bigger ones, although it depends on how we define "big". However, all the waterfalls that we can locate throughout our world fall short if we compare them with those that were once in the past.
The Dead Sea was probably devastated by a meteor 3,700 years ago
The Dead Sea was probably devastated by a meteor 3,700 years ago
About 3,700 years ago, as preliminary results presented at the annual meeting of the American Schools of Oriental Research suggest, the heat wave unleashed by an explosion in the sky destroyed cities and agricultural settlements north of the Dead Sea. This cataclysm instantly destroyed civilization on a 25km wide circular plain called Middle Ghor.
Where is the ocean water going?
Where is the ocean water going?
A new study published in the journal Nature reveals some mysterious complexities about the water cycle of our planet, in particular, the amount of ocean water that is trapped inside the earth through plate tectonics. According to the study, the amount is about three times more than we thought.
This is the largest body of fresh water in the world but we cannot access it
This is the largest body of fresh water in the world but we cannot access it
All the water on Earth, 97.5% is salty and the other 2% is frozen in the polar caps. So what percentage of water can we drink? Well, we have approximately 0.5% of all the water in the world, so most of the world's drinking water is unattainable, for now, for us.
About seven millimeters a year: at this rate the fastest growing mountain in the world grows
About seven millimeters a year: at this rate the fastest growing mountain in the world grows
The orography changes over time, although it does so at a rate so delinquent that it is impossible for us to register with our senses. In fact, there are mountains that grow over time. The one that does it at the fastest speed of all is the Nanga Parbat, in Pakistan. Nanga Parbat There are still mountains that have not been able to climb for the human being, like this one, although it is not the highest in the world.

Would you buy Martian land for $ 20 per kg?
A custom of some travelers is to bring a small stone or some earth from the exotic place they have visited. Can you imagine a sample like that but from Mars? Better: a sample of Martian land without traveling to Mars. And, in addition, for the affordable price of 20 dollars a kilogram.
Humans are responsible for some of the oscillations in the Earth's turn.
Humans are responsible for some of the oscillations in the Earth's turn.
We already explained what would happen if all the Chinese in the world jumped simultaneously. Advance: no, the Earth's orbit would not change one iota. However, ironically, all of us are responsible for some of the oscillations in the Earth's turn. Although not in the way we believe.
This well in China is so deep that it crosses Cretaceous strata
This well in China is so deep that it crosses Cretaceous strata
The well is located in the Songliao Basin, one of the largest continental sedimentary basins in the world. And it is so deep that, for the first time, it has penetrated a continental layer of strata from the Cretaceous period of the Earth. Located in the basin that has the most important reserves of oil and natural gas in China, the well is specifically 7.
How many mountains over seven thousand meters have not been climbed yet?
How many mountains over seven thousand meters have not been climbed yet?
On Earth there are 169 mountains that exceed 7,000 meters of altitude. Of these, the human being has scaled almost all of them, because they have only ten left to crown (for now). The highest in the world (without climbing) Of the 40 highest mountains in the world, only two were left uncrowned in 1985.
