      New Clues May Help Predict Earthquakes

      Researchers could be closer to predicting earthquakes hours before they happen, with an article in the journal Nature detailing how scientists detected seismic changes in rocks as much as 10 hours before two small California temblors. “Hurricane [warnings] give you an idea of what could be done,” one researcher told the BBC of such a breakthrough—still perhaps years away in daily application.

      China Quake Beat the Odds

      The earthquake that leveled parts of China’s Sichuan province last month was a geological oddity arising from usually inactive faults, LiveScience reports. The bizarre seismological coincidences behind the quake explain why no one was able to predict the event, which claimed 69,000 lives. More »

      Big Quakes Beget More Shakes Worldwide

      Massive earthquakes like this month's in China's Sichuan province can quite literally make waves on the other side of the Earth, a new seismology study finds. The surface tremors resulting from events like Indonesia's tsunami-triggering quake in 2004 lead to increased seismic activity around the globe—from two to five times the average, LiveScience reports.

      5.2 Quake Again Rattles West

      The latest in a series of shakers to rattle the West was a 5.2 magnitude earthquake that struck a rural area 190 miles northwest of Sacramento last night. No injuries or damage were immediately reported.
