Coastal subsidence and precision GPS data helped scientists "anticipate" a major earthquake in Coast Rica, placing us one small step closer to earthquake prediction.
The obscure rare-earth metals turn out to be unexpectedly essential to life in hot volcanic mud--and probably elsewhere.
California's $25 billion fix for the Sacramento-San Joaquin Delta depends on making wildlife groups and water users happy. With the latest release of the state's plan, it's looking harder to do both.
A $100 million effort to push the world's cities toward better disaster resistance is making a test case with a "gang of four" Resilient Cities: Alameda, Berkeley, Oakland and San Francisco.
Drilling mud is the slick concoction used to cool and lubricate a drill bit, and it’s used for all kinds of wells, including oil and gas. Environmental groups are turning their attention to drilling mud, which is currently exempted from water monitoring.
After the massive destruction of the 1971 Sylmar earthquake, state lawmakers passed a law to prevent new buildings from being developed on top of active earthquake faults. But that requires knowing where they are. Mapping earthquake faults is both time-consuming and costly, and the state has a long way to go.
The short list of climate proxy species gains a new member in the critical Arctic Ocean region, a crusty red alga named Clathromorphum compactum.
Listening to the sped-up vibrations of earthquakes offers a tantalizing glimpse of the deep physics behind seismicity as well as everyday sounds.
Ancient ice is an important source of information about global climates of the past. Although the ice itself is a valuable record, the real prize is the air bubbles preserved in it, some that could be as much as 1.5 million years old.
Slowly and painstakingly, geologists are turning the imaginary time scale of Earth's deep history into exact boundaries marked on the ground with metal disks.
A newly published study from the University of Washington demonstrates how we can forecast landslides that will follow a major earthquake in the Bay Area.
Nature shows almost no signs of the Loma Prieta earthquake 24 years later. But the human landscape still carries scars that should remind us to practice continual preparedness.
California governor Jerry Brown signed legislation over the weekend that reaffirms the state’s commitment to working with Nevada to preserve Lake Tahoe.
Scientists are creeping their way toward better understanding of earthquake swarms, those annoying and sometimes damaging seismic pests we get in California.
The practice of science is like the practice of juggling: it all depends on the skill and trust of partners. The late Terry Wright, professor emeritus at Sonoma State University, was an exemplar of the type.
The rise of a small, fuming island after a large distant quake may not be such an exotic event. Look for one when the next Big One strikes California.
Two new papers shed light on the deepest earthquakes: one by documenting the largest deep event yet recorded, the other by reproducing these events at the nanoscale in the high-pressure lab.
A new climate chronology for California has come from one of our quintessential trees, the blue oak.
