The annual open-ended celebration of geology and its related sciences takes place all this coming week. See what's happening and where to take part.
Experts have tracked a group of rare meteorites back to a single source on Marsthe crater Mojave near the red planet's equator.
For long-term earthquake planning in the Mississippi Valley region, we need to know whether earthquakes are fading away, as some suggest, or not. A new study argues that we're in a "steady as she goes" phase.
Critical Zone Observatories, or CZOs, are designated sites around the world where scientists study the crucial environmental interactions that occur on the Earth's surface. This new frontier in research can lead to further insights on sustainable civilization.
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.
New tools and old-fashioned sleuthing have cleared away a century's worth of errors from our detailed picture of what the San Andreas fault did to Portola Valley in 1906.
The science of earthquake prediction is fraught with the human tendency to seek conclusions beyond the reach of the data. In this setting, even the fruitless hypothesis of sunspots is seductive.
In the new Gallery of California Natural Sciences, to be unveiled tomorrow, no one will mistake California for someplace else again.
