Performance and Progress of Earthquake Early Warning Systems Around the World
Earthquake early warning (EEW) systems aim to rapidly detect that an earthquake is happening and issue alerts for incoming shaking. Such systems can provide crucial seconds for people and automated systems to take protective actions before shaking arrives, potentially mitigating the impacts of damaging ground motions. The development and operation of EEW systems is a multidisciplinary effort at the intersection of seismology, engineering, and social science. Timely alerting requires both sophisticated network engineering to provide real-time seismic and geodetic observations as well as earthquake characterization algorithms that use small portions of these data to rapidly detect earthquake shaking and estimate ground motion distributions. Social science and emergency management research help determine what alert messages should say and illuminate public perception of the system’s performance. Selecting alerting strategies that balance tradeoffs among prediction accuracy, available warning time, and the level of shaking for which users desire alerts requires insight from all disciplines.
There are many EEW systems around the world that are in various stages of operation and development. The details of a given EEW system vary, but system operators look to each other for new ideas and lessons learned from recent earthquakes. This session welcomes contributions across all disciplines of EEW science, including abstracts that discuss the performance of current EEW systems, the development of new EEW approaches, and education and outreach efforts to encourage adoption of these systems.
