A new study adds strong evidence that deep-injection wells can occasionally nudge a fault into activity. The key is figuring out how it happens, then learning to avoid whatever is making it happen.
As a flood of new exoplanets swim into our ken, we have ways of turning these pixel-size steams of data into insights about our own planet.
New evidence from high-pressure experiments and earthquake waves suggests the presence of water-rich melt at the base of the upper mantle, far deeper than previous estimates.
Even before the drought, farmers around California were sucking down the groundwater faster than the environment could keep up. Now, the U.S. Geological Survey reports the practice has caused land in the Coachella Valley to sink up to two feet in some places. ...Read More
When future geologists, whatever species they may be, look for our signs in the fossil record of the future, it may be this newly described amalgam of plastic and sediment.
Recent cutting-edge techniques are opening a new approach for earthquake forecasts by matching foreshocks -- small quakes occurring on the same stretch of fault that subsequently fails in the large mainshock -- to changes on the seafloor.
A research expedition in the Gulf of Mexico has stumbled on a field of beautiful natural sculptures made of asphalt on the sea floor.
Power players in California water policy seem to agree for once: It's time to get serious about groundwater.
A group of biologists asks their peers to start documenting newly discovered and "rediscovered" species by non-destructive techniques instead of killing a specimen to bring home.
A new paper attempts to describe a realistic picture of the unimaginable: a colossal cosmic impact that left a crater 500 kilometers across on the ancient Earth.
50 years ago today, the Good Friday earthquake in Alaska sent shockwaves through earth science itself.
New research has mapped 19th-century earthquake ruptures along the San Andreas Fault in a study that combines geologic and human records.
And some say that a fracking boom in California will raise the ante.
A porpoise fossil has been unveiled as a unique mammal that skimmed the seafloor with its sensitive, protruding lower jaw.
A wave generated by Japan's monstrous Tohoku earthquake destroyed Crescent City's fishing harbor. Engineers say the new design should withstand a 50-year event.
No early reports of damage or injuries. Quake hit at 10:18 p.m., centered off Humboldt coast. ...Read More
Experts have tracked a group of rare meteorites back to a single source on Marsthe crater Mojave near the red planet's equator.
Elizabeth Kolbert’s book “The Sixth Extinction: An Unnatural History” centers around two premises: that humans are witnessing a very high rate of species extinction and that humans are causing much of it.
