Listening to the sped-up vibrations of earthquakes offers a tantalizing glimpse of the deep physics behind seismicity as well as everyday sounds.
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.
Scientists are creeping their way toward better understanding of earthquake swarms, those annoying and sometimes damaging seismic pests we get in 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.
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.
