Government researchers in China have asked a select group of farmers to monitor abnormal behavior among their livestock — behaviors that could be indicative of imminent earthquakes. »
If you want beautiful fireworks bursting in the sky, you’re going to need to mine the Earth first. Here’s the geology of the minerals that give fireworks their vibrant colours. »
Pixar’s geological love story Lava isn’t just meant to evoke the tropical islands of Hawaii; it’s actually inspired by a real underwater volcano off the coast of the Big Island. We spoke to the short film’s director and learned about the real geology simmering beneath Lava. »
On April 22, 2015, a stratovolcano in southern Chile called Calbuco erupted for the first time in 42 years. Filmmaker Martin Heck was in the area shooting a neighboring volcano, when Calbuco came alive. He fixed his cameras on its undulating plumes of ash. This gobstopping time-lapse is the fruit of the images he… »
At some future juncture, we’re going to need more living space, whether it be found on another planet or through the expanse of our planet’s existing surface area. In his latest venture into worldbuilding, Oxford University research fellow Anders Sandberg explores some of the more extreme possibilities.
When we think “ancient Mars,” we often picture roaring rivers, warm oceans, and if we’re being optimistic, perhaps some simple life forms. But it’s also possible the Mars of eons past was not a water-covered paradise at all. It may, in fact, have resembled a giant, dirty snowball. »
Two new studies show that current groundwater use has reached unsustainable levels, a “tipping point’ that threatens to undermine regional water security. »
“Are geologists... better than engineers? ... able to drill to the center of the Earth? ... the sexiest man [sic] alive?” Geologist Miles Traer (previously here & here) typed “Are geologists...” into Google then used the rest of the alphabet and auto-complete to finish the questions. He then did his best to answer… »
According to the Intergovernmental Panel on Climate Change, the world’s sea levels are poised to rise dramatically in the future — as much as 200 feet (60 meters) in some parts. China’s coastlines are considered to be among the most vulnerable areas, as conveyed by these rather disturbing maps.
Preparations for NASA’s next mission to Mars are kicking into high gear. And the technology the space agency is building for the Martian lander slated to launch in 2016 is enough to make science fiction fans foam at the mouth. »
No, these aren’t about to hatch out and reveal a bloodthirsty monster with acid blood. They’re spherical rock formations, created by the natural processes of sedimentary concretion and erosion. But they really, really look like alien eggs. Check out some fascinating videos of spherical rocks all over the world. »
Glaciers around the world are in retreat, but not Alaska’s Hubbard Glacier. It’s steadily advancing into Disenchantment Bay, threatening to block the entrance to Russell Fjord and disrupt life in the nearby town of Yakutat. »
Roughly 3.3 billion years ago, Earth’s early life forms were plunged into an unimaginable hell, when a series of massive asteroids smashed into the young planet, vaporizing the oceans and scorching the skies. »
This satellite image of Washington’s Mount St. Helens comes courtesy of NASA’s Earth Observatory, which notes that tomorrow is the 35th anniversary of the volcano’s eruption and subsequent landslide, which killed 57 people. Scientists still keep a close watch on the site from both the air and ground. »
This past weekend, a rare underwater landslide in the town of Sørkjosen, Norway, resulted in extensive damage to a wharf, some buildings, and a sea wall. Local authorities have shut down a major road for fear it too could be sucked into the sea, resulting in a 435-mile (700-km) detour. »
Don’t worry. This isn’t a repeat of Dressgate, nor is it a matter of perception. Iolite, or cordierite, really does change color depending on where the light is coming from. Find out why. »
