PASADENA (AP) — California has received a spurt of federal funding to expand an earthquake warning system intended to provide enough time for trains to brake, utilities and factories to shut off gas lines, and people to dive under a table until the shaking stops. But the money is far short of what’s need to finish the job statewide. California trails Japan, Mexico and other earthquake-prone areas in developing a public alert system, which ideally would provide several seconds of warning after a fault ruptures.
