A prototype, earthquake early warning system, worked as designed when an actual quake gently shook California last Friday. Researchers reported the results Tuesday at the annual meeting of American seismologists.
Last year, a private foundation in collaboration with the U.S. Geological Survey gave a multimillion dollar grant to create an automated earthquake warning system for the Pacific Coast states. The idea is to provide advance notice to prepare people for severe shaking. It could come via a cell phone alert or a pop-up on your computer or TV screen.
