If you’ve had your fill of depressing predictions for the future, here’s one that is both fascinating and as innocuous as they come: as ice caps melt, Earth’s rotation is slowing down, and that’s making our days ever so slightly longer.
It took 2,500 seismometers, 23 explosive blasts, and countless earthquakes, but researchers now have a much better idea of what the magma chambers look like deep below Mount Saint Helens. The weird bit? It looks like it shares a magma chamber with a whole field of local volcanoes.
What lurks beneath the dusty red surface of Mars? NASA’s InSight Lander is launching next spring to go delving deeper than ever before as the first Martian geophysicist.
Earthquakes can create copycat events up to 1,000 kiometers away — and it could be the result of the vibration of small particles, according to new computer simulations of seismic activity in the Earth.
It’s often said that we know less about Earth’s deep interior than we do about the surface of Mars (or at this point, maybe even Pluto). A new global map of subatomic particles called antineutrinos is helping to change that. It’s showing scientists just how radioactive our little Blue Marble is.
The explosions that devastated Tianjin yesterday were so powerful, they registered as seismic activity by China’s National Earthquake Network. And the “quakes” geophysicists saw don’t even begin to capture the magnitude of the blasts.
In 1982, the ground beneath the historic port city of Pozzuoli began to rise like a cake in the oven. Within two years, the swell had exceeded 6 feet. Then the earth started shaking—first, a swarm of microquakes. When the first magnitude 4 quake hit, Pozzuoli became a ghost town overnight.
Standing on the surface of Venus, your body would be crushed by the immense pressure, fried by the lead-melting heat, and dissolved by sulfuric acid thunderstorms. Too bad, because if you could survive on Venus, you might witness some epic volcanic eruptions.
Your typical thunderstorm strikes in summer, when the atmosphere is full of warm, moist air. So when lightning strikes in the middle of a winter blizzard, there is something strange going on. Thundersnow involves an entirely different type of lightning, and our skyscrapers are a key part of it.
From a satellite, the plumes venting from two volcanoes in the Democratic Republic of the Congo look like clouds. Right now, they're just spewing harmless steam and gas. But that could change.
At school, we were all taught that volcanoes—just like the one rumbling away in Iceland—erupt when narrow jets of magma are forced outwards from the core of the Earth. It's a compelling enough story that it's appeared in textbooks for decades—but it's also, apparently, completely wrong.
Yellowstone National Park is riddled with constantly changing geothermal hot spots—it's part of the reason for the park's famous geysers. But this past Thursday, the area around one section of road got so hot that asphalt literally started melting.
The Earth's magnetic field protects life on Earth, shielding it from damaging radiation and moderating our climate. So the idea that it could completely flip around, or collapse altogether, should cause us to worry, right? Well, yes and no.
Around 3.26 billion years ago — long before the dinosaurs — a massive asteroid measuring nearly 36 miles (58 km) across smashed into the Earth. Geologists have now reconstructed this cataclysmic event, and it was far, far bigger than we thought. Here's how things went down on that fateful day.
Everyone knows that Yellowstone is home to a super-volcano—but it turns out that the magma reservoir it sits atop is at least 2.5 times larger than we previously thought.
Gravity's often assumed to be constant across the entire planet, but because the Earth varies in shape and density, that's not really the case. Now, this super-accurate gravity map reveals that the fluctuations are even more extreme than scientists previously thought.
This is a light that never goes out: an eternal flame, hidden behind a waterfall in Erie county, New York, which is a result of natural gas seeping out from underground rocks.
This week, a group of geologists report that they've found a lost continent off the coast of Scotland. 55 million years ago, about 10 million years after dinosaurs died out, a chunk of the seafloor erupted from beneath the water. It created a small continent that existed for at least a million years, covered in…
