Have you ever felt an earthquake? What was it link? What did you do? More than 143 million people are exposed to potentially damaging shaking in the United States. The US Geological Survey (USGS) along with universities and state agencies in Washington, Oregon, Nevada, and California are developing the ShakeAlert Earthquake Early Warning (EEW) System for the West Coast. Several Counties including Japan, Mexico, Taiwan, and China already use EEW systems. A ShakeAlert can also be sent to a hospital, a light rail system, a fire station, a water provider utility, or a school to trigger automated actions such as starting emergency generators slowing down trains, opening fire house doors, closing water system valves, or playing a pre-recorded message on a loudspeaker.
