Performance, Progress, and Promotion of Earthquake Early Warning Worldwide
Session ID#: 162091
Session Description:
In 1993, Mexico initiated the first earthquake early warning (EEW) system with public alerting. The United States, Japan, Taiwan, India, Romania, Israel, Italy, New Zealand, and others are now in various stages of development and deployment of EEW systems. EEW pushes the frontiers of science and engineering yet is an inherently social and humanitarian effort to protect people and key infrastructure from the effects of strong ground shaking. EEW alerts must be issued quickly to provide actionable warning; thus, we must find novel solutions to detect, characterize, and communicate expected shaking based on limited observations. This session explores innovations in data acquisition and telemetry; geophysical algorithm developments that determine alert regions; and education and messaging tailored to mitigate risk and meet societal needs. We welcome abstracts on the intersection of earthquake science, engineering, technology, education, and social science that improve the reliability and utility of EEW systems.
