Sentinel Satellite Reveals the Aftermath of Napa's Earthquake

During the morning of August 24, California's Napa Valley was struck by its biggest earthquake in a quarter century. The ESA's brand new Sentinel-1A satellite has now produced an unprecedented visualization of the ensuing rupture. » 9/02/14 2:48pm 9/02/14 2:48pm

An earthquake threat is building up in the central U.S.

Seismologists have found that, contrary to popular thought, earthquakes in the central U.S. are not slowly tapering off — instead the threat appears to be building. » 1/23/14 3:14pm 1/23/14 3:14pm

Yellowstone's Megavolcano is more than twice the beast we feared

Beneath Yellowstone National Park lurks a vast caldera – a high-pressure volcanic cauldron brimming with enough gas and magma to make Mount St. Helens' 1980-eruption look like a middle school science project by comparison. Now, newly reported findings suggest this megavolcanic reservoir is even bigger than previously… » 12/13/13 8:00am 12/13/13 8:00am

Watch as an earthquake sends a massive wave across the US

The USArray project has produced a remarkable animation showing how earthquake waves travel across massive expanses of landmasses. As you'll see in this video, these waves are a lot like ripples on a pond. Very powerful ripples. » 10/30/13 6:20am 10/30/13 6:20am

Comment of the Day: Cat Seismology Edition

In today's comments we watched NASA's website go (temporarily?) dark, talked about the off-screen deaths of our favorite characters, and learned the theory behind your pet's curious pre-earthquake behavior. » 10/01/13 5:48pm 10/01/13 5:48pm

This is what it looks like when a building implodes

You hear the phrase "implode" all the time, but what does it really mean? Now you can find out, in this video of a Cal State Hayward building being neatly demolished over the weekend. » 8/19/13 4:50pm 8/19/13 4:50pm

Yellowstone's megavolcano is more terrifying than we ever imagined

A seismology student from the University of Utah is claiming that the volume of molten magma beneath Yellowstone is 50% larger than previously thought. Given that the caldera could blow up at anytime and with little warning, that's a pretty scary thought. » 4/18/13 4:18pm 4/18/13 4:18pm

A monster truck that pounds the ground to simulate earthquakes

Geologists in New Zealand have a new tool to help them measure the effects of earthquakes. It's called T-Rex, a 64,000 pound (29,000 kilogram) shaker truck that's being provided by the U.S. Network for Earthquake Engineering Simulation. » 1/31/13 7:20am 1/31/13 7:20am

'Perfect storm' of geological factors make the Eastern U.S. more…

As if the folks out on America's east coast don't already have enough to worry about after the onslaught of Hurricane Sandy, it now looks like last year's magnitude-5.8 earthquake in Virginia was no anomaly. According to a report presented this week at the Geological Society of America's annual meeting, the highly… » 11/08/12 10:27am 11/08/12 10:27am

Six scientists convicted of manslaughter for failing to warn citizens…

Six Italian scientists and one government official face six-year jail terms for failing to warn citizens about the ravaging effects of the L'Aquila 6.3 magnitude quake that killed 309 people in 2009. This morning, it took Judge Marco Billi just over four hours to reach this verdict. » 10/22/12 7:50am 10/22/12 7:50am

A Luminescent Map of the World's Earthquakes Since 1898

You're looking at the latest work of John Nelson, who is becoming well known for combining natural-disaster data with brilliant visualizations. The Michigan-based designer first captured our attention with a series of fantastic maps of U.S. tornado data. Now, he's used his talents to chart a century's worth of… » 7/06/12 1:44pm 7/06/12 1:44pm

Burying greenhouse gases underground could cause earthquakes

As the Arctic ice continues to fade away, some scientists have come up with radical solutions to the problem of greenhouse gases. One of these ideas is large-scale Carbon Capture and Storage (CSS), burying those troublesome gases underground — but now it looks like that notion could cause more trouble than it's worth. » 6/19/12 5:01pm 6/19/12 5:01pm

X-rays reveal why the Moon has no volcanoes

The Moon is an almost completely still world, its eternal peace and quiet disrupted only by the occasional meteor or Apollo astronaut. But we now know there's plenty of magma inside the Moon. So why are there no volcanoes? » 2/19/12 4:00pm 2/19/12 4:00pm

An Early Warning System to Predict the Next Supervolcano Eruption

We can't predict a volcanic eruption more than a few days or months in advance. But one of the most devastating eruptions in human history could give us a huge boost in predicting the next massive volcano. » 2/02/12 11:17am 2/02/12 11:17am

Major earthquakes might be triggered by hurricanes

While predicting the next big earthquake is probably impossibility, there's still a lot we can learn about what causes severe earthquakes. We've now identified the trigger for some of the most destructive recent earthquakes, including the 2007 quake in Haiti. » 12/08/11 11:20am 12/08/11 11:20am

What it's like to be trapped in the Washington Monument during an…

Last month's earthquake in Virginia rattled the 555-foot-tall Washington Monument such that it's been closed indefinitely so engineers can assess damage. Buildings all across the Eastern Seaboard were rocked on August 23, but the Monument's security camera footage shows that people visiting the famous obelisk had a… » 9/27/11 7:20am 9/27/11 7:20am

How could an earthquake happen in Virginia?

According to the U.S. Geological Survey, the small town of Mineral, Virginia was was the epicenter of a 5.9 magnitude earthquake earlier this afternoon, making today's quake at least equal in intensity to Virginia's largest earthquake on record, which the USGS says occurred in Giles County, Virginia in 1897. » 8/23/11 12:45pm 8/23/11 12:45pm

East Coast of US shaken by Virginia earthquake

I don't know if any of you on the East Coast of the United States felt that earlier this afternoon (I felt it here in New York City), but according to the United States Geological Survey, a 5.9-magnitude earthquake just hit Mineral, Virginia, a town 100 miles south of Washington DC, shortly before 2:00 PM EST. » 8/23/11 11:06am 8/23/11 11:06am

The Earth's core melts and freezes all at the same time

The inner core of our planet is roughly as big as the Moon, and we can only guess what's going on deep inside our planet. We might now have an answer...and it's even more volatile and weird than we thought. » 5/18/11 10:34am 5/18/11 10:34am
