    How the Right Mattress Can Ease Back Pain
    Pedestrians stop to examine a crumbling facade at the Vintner's Collective tasting room in Napa, Calif., following an earthquake Sunday, Aug. 24, 2014. Officials in the city of Napa say 15 to 16 buildings are no longer inhabitable after Sunday's magnitude-6.0 earthquake, and there is only limited access to numerous other structures.

    The 6.0-magnitude earthquake that shook California’s Napa Valley early Sunday morning was the biggest temblor to hit the area since 1989, but trends show another -- larger -- quake may be on its way. "There is always that possibility," Cecily Wolfe of the USGS Earthquake Hazards Program told NBC News. "It's small, but any time you have an earthquake, the probability of another earthquake goes up." There is currently a 5 to 10 percent chance of something bigger than a 6.0-magnitude quake coming in the next week, according to the Northern California Seismic System report.
