The Earthquake A major earthquake hit a remote part of Pakistan (near the border with Iran), claiming 45 lives and prompting a new island to rise from the sea just off the country’s southern coast. According to the USGS, the earthquake has a magnitude of 7.7 and tremors were felt all the way to New […]
A magnitude 8.3 earthquake that struck deep beneath the Sea of Okhotsk on May 24, 2013 still poses a lot of questions to geophysicists. At a depth of about 609 kilometers (378 miles), the kind of rupture which generates an earthquake of this magnitude should just not happen. The vast majority of significant earthquakes takes […]
Could the Yellowstone supervolcano be waking up? In his 53 years of monitoring seismic activity in and around the Yellowstone Caldera, Bob Smith has never witnessed two simultaneous earthquake swarms; now, the Utah University geophysicist has seen not two, but three such swarms. “It’s very remarkable,” Smith said. “How does one swarm relate to another? […]
Instead of digging through layers of rocks, a few paleontologists focused their efforts on ‘digging’ through museum collection instead – and their efforts were quite successful. Their unique approach led to the discovery of never-before seen structures, which they think are something called dino-fuzz. The fluffy structures trapped in the small bits of ancient amber […]
When the Sahara comes to mind, lush greenery and gorgeous, fast flowing waters might be the last scenery that crosses you. Not too long ago (geological frame), however, the region known today as the Sahara may have been crossed by three giant rivers the size of the Nile, according to a recent palaeohydrological model made […]
Geophysicists trying to understand hotspot volcanoes have used a process known as seismic tomography and detected previously unknown finger-like structures of heat, some thousands of km long. The vast majority of volcanoes arises at contact zones between tectonic plates. However, another, entirely different type of volcano exists: hotspots are volcanic regions which can appear even […]
Land clearing and human habitation put significant pressure on local species – combine this with globalization and a general recklessness of the population, and you get a big, negative impact (both environmental and economic) from invasive plants. But invasive plants aren’t something new – they’ve been around for hundreds of millions of years. Scientists have […]
A 350 million year old fossilized scorpion has become the world’s oldest known land animal to have ever walked the supercontinent Gondwana. Ancient history It’s 350 million years ago – take a moment to ponder that. Take a long human lifespan of 100 years, and multiply it by 100, and again by 100 – now […]
Geophysical data from Greenland have revealed the existence of a canyon comparable in size with the Grand Canyon beneath the ice sheet. The canyon has the characteristics of a winding river channel and is over 750 km long and it is often as deep as 800 m. This immense feature is thought to predate humanity […]
A surprisingly diverse range of life forms exists deep in the oceanic crust, but they live at an extremely slow pace. Long lived bacteria, which reproduce only once in 10.000 years, have been found in rocks 2.5km below the ocean floor, rocks which are 100 million years old. Viruses and fungi have also been found […]
A fossil of a small, forest-floor-dwelling animal called Megaconus puts a big question mark on the evolution of mammals – it suggests that its group predated animals, while another one, from its tree dwelling ‘cousing’ Arboroharamiya shows the group belonged to the mammals. The two fossils have paleontologists scratching their heads, not knowing where to […]
A new, unusual species of dinosaur has been discovered in the deserts of Utah. The 5m-long is a member of the triceratops family, and as fierce as they may look, this dinosaur was a herbivore. The huge ‘nose’ and exceptionally long horns are unlike any other dinosaurs previously described, which explains its name – Nasutoceratops […]
The king of all predators, the godfather of his time, la creme de la creme – Tyrannosaurus Rex (T. Rex) was the ultimate predator… or was he? When Jurassic Park came out, even though the cinema crowd went wild as T. Rex smashed and ate velociraptors (and the occasional human), at the time, there was […]
Lots of volcanoes erupted in 2009 – but one of them really screamed out. Its unique howls provide a glimpse into the very heart of the volcano, and also in some unexplained processes that accompany an eruption. It’s not unusual for swarms of small earthquakes to precede a volcanic eruption – it’s quite common. As […]
A trio of papers recently published in Science link hydraulic fracking and geothermal energy production to numerous earthquakes in the United States. Most of these events have been relatively small, with a magnitude of under 5.0, but a few were quite significant – including the 5.6 event that hit Oklahoma on 6 November 2011, damaging […]
Scuba divers have discovered a primeval underwater forest off the coast of Alabama – a cypress forest which was incredibly well preserved for over 50.000 years. The bald cypress forest was buried under ocean sediments (almost certainly sand), isolated from oxygen (which is the main enemy of preservation), thus preventing them from rotting; however, the underwater […]
Rock permeability in the geologic fault that unleashed China’s 2008 quake shows that fractures mend quicker than was thought. A devastating earthquake The 2008 Sichuan earthquake struck at 02:28:01 PM China Standard Time, with a magnitude of 8. It came as quite a surprise, as the area is not particularly active from a seismic point […]
More and more discoveries seem to hint at a watery past for Mars. Now, NASA research shows that hunks of frozen carbon dioxide (dry ice) may glide down some Martian sand dunes on cushions of gas similar to miniature hovercraft, plowing away as they go down. This study could explain one of the mysteries of […]
Typically on Earth, days usually have a temperature maximum somewhere after lunch, and a minimum during the night. But for Mars, things are pretty different: “We see a temperature maximum in the middle of the day, but we also see a temperature maximum a little after midnight,” said Armin Kleinboehl of NASA’s Jet Propulsion Laboratory […]
You may have heard about the Tunguska event – a huge blast of energy which occurred in 1908 over Russia and flattened more than 2,000 square kilometres of forest. More than a century since, its remarkable that scientists have yet to confirm the source of what undoubtedly is the biggest Earth impact in recorded history. The leading […]
Living fossils, fast adapters Sturgeons have been conserved as fossils ever since the early Cretaceous – some 130 million years ago; they are what we call ‘living fossils’. But a new study by University of Michigan researchers revealed that in some aspects, sturgeons are one of the fastest-evolving fish on the planet. “Sturgeon are thought […]
If you’ve ever visited a cave, you probably know the golden rules: Watch you’re head, stay on the track, and keep your grase paws off the formations! Why the last one? Well, because the hands and dirt you have on your hands can impede their growth. But when you go inside a cave as a […]
At 55 million years old, it represents the earliest known member of this broad group of animals that includes humans. It may be no bigger than a mouse, but it is a primate, and a very valuable one at that; paleontologists have named it Archicebus, which roughly translates as “ancient monkey”. The team which described […]
As bad as earthquakes can be, and we’ve recently had our fair share of earthquakes around the world, the tsunamis they generate can be even worse. When an earthquake has a significant effect in a body of water, it displaces large quantities of water – and it is that displacement which causes the huge waves […]
In a quest to make concrete not only more durable but also more sustainable, a group of geologists and engineers have found inspiration in the ancient Romans – whose imposing buildings have passed the test of time, surviving two millennia. Geology and the Romans Using classic microscopy, as well as the Advanced Light Source at […]
Despite the fact that triceratops are some of the most well known dinosaurs, finding a complete skeletons is an extremely rare treat. It was one of the last non-avian dinosaur genera to appear before the Cretaceous–Paleogene extinction event – the extinction which caused the end of dinosaurs and the Mesozoic. The scientists from the Black […]
The only two (significant) places in our solar system, that we know of, which can create opals are Central Australia and Mars, so by studying the geologic processes which led to the creation of these minerals in the first place, we can perhaps find out more about the Red Planet. As a geologist, I was […]
Detailed analysis and review have confirmed the scientists’ initial opinion – the pebble containing slabs Curiosity stumbled upon last year were indeed part of an ancient streambed. When the Curiosity rover landed on Mars, it was expecting to find lots of things – but finding evidence of ancient water so close to the land site […]
NASA’s GRAIL mission had been studying the Moon’s gravitational field for 9 months, with great results – they have discovered the massive regions which cause irregularities in the Moon’s gravitational field, making it uneven. Planetary gravitational fields The Earth, the Moon, and pretty much all planets have irregular gravitational field – first of all because […]
The fossil, which still retains impressions of feathers, is 160 million years old, predating the oldest Archaeopterix fossil found by 10 million years. Scientits have named it Aurornis, which means “dawn bird”. Aurornis and Archaeopteryx Aurornis enables us not only to better understand the emergence of birds, but also to understand how powerful flight originated. […]
Well the title may be a little flashy, but here’s what it’s about: some highly unusual minerals have been found at the centers of impact craters on the moon. Geologists working on the case believe that they may be the shattered remains of the space rocks that made the craters, but didn’t exhume any material […]
Usually, species are named after defining trait, or sometimes, more rarely, after somebody famous in the field, but every once in a while, they get some rather cooky names – like is the case with Kooteninchela deppi. Cambrian and scrissors Pronounced Koo-ten-ee-che-la depp-eye, the 505-million-year-old fossil is a distant relative of lobsters and scorpions, and […]
A paleoclimate study has shown that a huge mass of warm water stretched out from Indonesia over to Africa and South America four million years ago had a huge impact on tropical changes, suggesting that current climate models are a too conservative. The Pliocene era started 5.332 million years ago and lasted until 2.588 million […]
New research by The Open University and Lancaster University showed that another type of volcanic eruption in Iceland could cause significant disruption throughout the Old Continent. Published in Geology, the study found magma that is twice as ‘fizzy’ as previously believed, which increases the likelihood of disruptive ash clouds from future eruptions. Magma can […]
Usually, the military taps into what science does and uses its technologies – but for once, it was the other way around. Using unmannes planes typically designed for city warfare, scientists were able to keep track of toxic volcanic fumes. The Dragon Eye remote-controlled plane weighs in at just under 6 pounds (2.7 kilograms), with […]
While taking a walk with her parents on U.K.’s Isle of Wight (map) in 2008, Daisy Morris, who was then no more than 5 years old, came across blackened “bones sticking out of the sand”. Her family took the bones to paleontologist Martin Simpson at the University of Southampton, who, with the help of colleagues, […]
The current leading theory that explains the mass extinction of the dinosaurs – once the dominant group of animals on Earth for millions of years – states that an asteroid impact some 65 million years ago brought their demise, wiping them out along with 70% of all life on the planet. A new study, however, […]
Some 200 million years ago half of all life on Earth went extinct, thus providing a window of opportunity for the dinosaurs to evolve in now unoccupied niches and dominate the planet for the next 135 million years. Curiously enough, after the dinosaurs were at their own term wiped out by a calamity – presumably at the […]
Almost always I happen to discuss global warming, something that often comes up. Still, the Earth was hotter in its history, like say right after the Cretaceous, so what’s the problem? In this article, we’re gonna clarify the aspects that differentiate those geologic periods from nowadays. Some sixty million years ago, there was virtually no […]
Scientists at Scripps Institution of Oceanography at UC San Diego have found a layer of liquefied molten rock in Earth’s mantle that may be acting as a lubricant for the sliding motions of the planet’s tectonic plates. This discovery has very far reaching implications, which can solve some of the long standing geological puzzles, as […]
Millions of years ago, an ancient tectonic plate called the Farallon oceanic plate used to sit between the Pacific and North American plates. In time, the plate “disappeared” beneath the North American one, however geologists at Brown University have now found physical surface remnants of the plate under sections of central California and Mexico. The Farallon surface […]
A new theory based on a simple but viable geologic model claims that over 80 percent of all commercial gold deposits were formed in a flash. Gold seams are formed when mineral-rich waters flow through networks of cracks in rocks some 5-30 km deep. But the exact mechanism through which the gold is deposited is […]
Ok, so big news on the horizon: alien life forms have been found in a meteorite that recently crashed in Sri Lanka, on December 29, bringing along a new perspective on how we view the origin and movement of life. But… have they really? Well, sorry to burst your bubble ladies and gentlemen, but in […]
A new analysis of data from NASA’s Lunar Orbiter Laser Altimeter (LOLA) shows that molten rock created by lunar impacts has been around for much longer than previously believed. During its earliest days, the Moon was covered in an ocean of molten rock, pretty much like every planet out there. As that lunar magma ocean […]
Paleontologists spend a majority of their working years studying fossils with only one objective – to unearth a discovery that will further benefit mankind’s understanding of dinosaurs. One such recent discovery established the presence of a hitherto unknown herbivore dinosaur. This discovery was made possible thanks to efforts by Clint Boyd of the South Dakota […]
We have a rather sound image in our heads of Antarctica: cold, barren and damn well inhospitable. Million of years ago before a big freeze turned the continent into a huge popsicle, Antarctica was flat, covered in vegetation and riddled with flowing rivers and life. University of Arizona researchers have sampled key sediments from the Lambert Graben […]
Our understanding and appreciation of Mars has greatly shifted in the past decade alone. If previously scientists used to thought the planet had been dead and bared geologically-wise for billions of years, recent evidence shows that Mars has been marked by a series of geological events. Using radar technology, scientists have now found water-carved channels buried […]
By observing several indicators, a team of researchers from Oregon State University’s College of Earth, Ocean and Atmospheric Sciences concluded that in as few as 87 years from now, temperatures are expected to be bigger than anytime in the existence of the human species. Paleoclimatic research is providing a more detailed look on how the […]
Paleontologists from the University of Florida have unearthed remarkably well-preserved fossils of two crocodilians and a mammal previously unknown to science during recent Panama excavations that began in 2009. The animals lived during the Miocene, a period that lasted from about 23.03 to 5.332 million years ago; the flora and fauna from the Miocene was […]
Climate change deniers were ecstatic – our planet wasn’t warming as fast as models predicted it; ha! Everything crumbles down, global warming is a hoax and all is good in the world, right? Wrong. The main question in science is “Why?”, and researchers started asking the question. Are all the models wrong, is there something […]
