In-depth interviews will be conducted with the providers and users of the earthquake early warning system in order to establish a detailed understanding of its development, operation and deployment. An investigation of this experience with the world's only publicly available earthquake early warning system is needed to adequately identify transferable lessons which could inform decisions regarding the deployment of an early warning system in the U.S. and to enhance the understanding of human behavior in warning situations. ***
