Five seconds before the South Napa Earthquake struck, UC Berkeley’s ShakeAlert detected the quake.
Some parts of California’s mountains have been uplifted by as much as half an inch in the past 18 months because the massive amount of water lost in the drought is no longer weighing down the land, causing it to rise a bit like an uncoiled spring.
Italy is approaching the next frontier in earthquake forecasting: an "operational" system that will make quake forecasts routine, whose contents we can take in stride.
The Alquist-Priolo law keeps new homes away from active earthquake faults. But a study finds that the resulting 'fault zone parks' attract wealthy residents despite the seismic hazard.
New work shows that the simple mineral sphalerite has geochemical powers suitable for helping life to arise from precursors in the mineral kingdom.
A new paper marshals evidence detailing the catastrophic landslide and mega-tsunami that struck Lake Tahoe during the late Pleistocene.
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.
