People standing above the epicenter of a large earthquake will feel the ground shaking before people on the periphery of the quake. The same can be said of their smartphones.

Researchers at the U.S. Geological Survey are trying to figure out whether smartphones might be used to give earthquake warnings.

Ben Brooks, with the USGS, says if a computer was checking for simultaneous movement of a large number of smartphones, it could give people on the periphery of a quake a 10-or-20-second warning.
He says that's enough time to stop a surgeon from starting an operation.

The Clackamas County Sheriff's department has identified victims of Tuesday's shooting at Clackamas Town Center mall. 

The victims who died were 54-year old Cindy Yuille, a registered nurse, and 43-year-old Steven Forsyth from West Linn, who owned a business in the mall. There's no information about how or when their deaths occurred. Police also didn't have specifics about whether the shooter killed himself before or after police saw him. 

It turns out Americans facing death want something they also want in life: choice.
