Amazing interactive globe shows the very different location of your city 750 million years ago

Earth has changed quite a bit in the past 750 million years or so. Due to plate tectonics—the shifting of the Earth's surface—the location of your city is likely far from where it is today. Computer scientist Ian Webster created this stunning interactive "Ancient Earth Globe" that pinpoints your city where it was located at various points in deep history, from 20 million to 750 million years ago. You can also learn about what was happening with the flora and fauna at the time. From CNN: ...

Scientists see an earthquake boomerang back and forth in the Atlantic

An earthquake ran quickly east before turning west beneath the Atlantic Ocean near the equator in 2016.Such earthquakes are likely to pack significantly more destructive power.Land-based boomerang earthquakes may have been witnessed, but have never been recorded seismographically. It was definitely an odd story Rosario García González told in the summer of 2010.González is an elder of the indigenous Cucapah community in Baja, California/Mexico. He and his wife were in their trailer in Paso Infe...

Terrawatch: lasting legacy of Taiwan's 2009 typhoon season

Typhoon Morakot left country with more quakes after changing stress pattern in Earth’s crustEleven years ago, Typhoon Morakot slammed into Taiwan, deluging the country with 3,000 litres of rain per square metre in three days. Catastrophic flooding and landslides followed and more than 600 people died.It is considered one of the worst tropical cyclones in Taiwan’s recorded history. But that wasn’t the end of it. New research reveals that the typhoon also left Taiwan with a legacy of extra earthqu...

Ancient Mars May Have Been Less Wet Than We Thought

Ice sheets, and not rushing rivers, sculpted many Martian valleys, according to scientists. The new research suggests ancient Mars wasn’t as warm and wet as we thought, but an expert we spoke to remains unconvinced.Read more...

This might be the oldest creature to have ever lived on land

An ancient millipede-like creature living in Scotland may have been the first creature to live on land.A fossil representing Kampecaris obanensis was first discovered in 1899 on the Scottish isle of Kerrera. It's now been radiometrically dated to 425 million years ago. If the new research is correct about the age of the fossil, then scientists have been greatly underestimating how rapidly bugs and plants evolved to transition to life on land. Scientists now believe that a fossilized relative o...

A landslide is imminent and so is its tsunami

A remote area visited by tourists and cruises, and home to fishing villages, is about to be visited by a devastating tsunami.A wall of rock exposed by a receding glacier is about crash into the waters below.Glaciers hold such areas together — and when they're gone, bad stuff can be left behind. The Barry Glacier gives its name to Alaska's Barry Arm Fjord, and a new forecasts trouble ahead.Thanks to global warming, the glacier has been retreating, so far removing two-thirds of its support for ...

Is poop-filled drinking water what killed ancient giant sloths?

Evidence collected from an ancient boneyard in Ecuador suggests that a group of 22 ancient giant sloths died in a wallow of their own feces. Other mammals, such as a deer, a horse, an elephant-like creature called a gomphothere, and another species of ground sloth were identified at the site. The fate of the sloths parallels that of modern hippos who can become lethally poisoned in times of drought when the feces to water ratio shifts in their watering holes. Evidence collected from a fossil t...

Gloriously colorful new geologic map of the moon

These images are from the new Unified Geologic Map of the Moon, the most detailed lunar map ever created. Just released by the U.S. Geological Survey, it melds data from last century's Apollo mission era with fresh information captured by NASA’s Lunar Reconnaissance Orbiter and the Japanese Aerospace Exploration Agency’s SELENE lunar orbiter. From Science News: Each splash of color identifies a discrete rock or sediment formation, including craters, basins and ancient lava fields. For...

Earth may have been a 'water world' 3bn years ago, scientists find

Chemical signatures in ancient ocean crust point to a planet without continentsScientists have found evidence that Earth was covered by a global ocean that turned the planet into a “water world” more than 3bn years ago.Telltale chemical signatures were spotted in an ancient chunk of ocean crust which point to a planet once devoid of continents, the largest landmasses on Earth.

NASA provides first evidence of “marsquakes”

The spacecraft InSight detected tremors from deep underneath the rust-colored surface of Mars indicating, for the first time ever, that the planet is geologically active. The quakes could potentially give seismologists insights into the interior composition of the planet.The Insight lander also uncovered magnetized rocks "consistent with a past dynamo with Earth-like strength" under the surface of the landing sight. Stirrings detected from deep below the surface of the Red Planet indicate, fo...

The scientific secrets inside a single grain of moon dust

While scientists have studied Moon rocks for 50 years, researchers have for the first time conducted deep analysis on a single grain of lunar dust, atom by atom. Using a common materials science technique called atom probe tomography that's not widely used by geologists, the Chicago Field Museum's Jennika Greer and colleagues probed the grain of soil -- about the width of a human hair -- and were able to learn about the Moon's surface its elemental composition. From the Field Museum: In...

Earth’s Oldest Asteroid Impact is Two Billion Years Old

The oldest asteroid collision on the planet, the Yarrabubba impact crater in Western Australia, is a whopping 2.229 billion years old. After analyzing minerals at the crater site, researchers have found the asteroid hit at the end of an era called Snowball Earth (one of the planet’s ice ages). Scientists, led by Dr Timmons Erickson (a geochronologist at Houston’s NASA Johnson Space Center), studied around …

What Are Sinkholes and How Do They Work?

A sinkhole opened up and swallowed a bus this week in China, killing several people. A few months ago, another sinkhole opened up below a bus in my hometown of Pittsburgh; in that case, though, everybody escaped safely. Besides buses, sinkholes can also swallow cars, pedestrians, and houses. Here’s the rundown on what…Read more...

A tectonic plate may have split apart, pulling Europe toward Canada

Geologists have long puzzled over a flat, featureless region off the coast of Portugal that's been the location of several earthquakes.A team may have confirmed that a drip-shaped mass, buried 155 miles below the seafloor, might be responsible for the seismic activity.If confirmed, the drip-shaped anomaly also suggests that geologists have for the first time observed the early stages of a subduction zone. None Since 1969, some geologists have been puzzled by a 7.9-magnitude earthquake struck off...

'Hovercraft effect' may explain deadly speed of volcanic gas clouds

Superheated gases and rock fragments can reach speeds of up to 400mph by travelling on cushion of air, say scientistsCrouched figures, a child with its mother, a dog writhing on its back – the harrowing plaster casts of the dead of Pompeii reveal that when the end came in AD79, it was as swift as it was final.Caught in the eruption of Mount Vesuvius, many died when buildings collapsed under heavy ash and pumice. But for those still alive, another catastrophe was about to hit as deadly currents o...
