According to a Field Poll, about six in ten people think it will hit sometime in the next ten years. Geologists say they're right to be worried. They think there's a 99 percent chance that California will have a quake with at least a 6.7 magnitude in the next decade or two. They're especially worried about the Hayward Fault.
Fifty-seven percent of Californians put earthquakes as their top concern; wildfires came in second; 23 percent said wildfires scare them the most; tsunamis came in third; 5 percent are nervous about mudslides.
The Field Poll was taken earlier this month. Experts hope all this anxiety over earthquakes will translate into people getting prepared, having earthquake kits in their homes and an emergency plan in place.
