Earthquake Early Warning Live in California! Current Status and Challenges

In October 2019, Earthquake Early Warning (EEW) alerts were made publicly available throughout California for the first time ever. This milestone followed closely on the heels of the 2019 Ridgecrest sequence, which included both the largest main shock and the most energetic aftershock sequence encountered by the US ShakeAlert EEW system (with public alerts only available in Los Angeles at that time). These events contributed to the already rapidly advancing realm of EEW research, which spans a wide range of fields including computer science, earthquake physics, seismic network design, social science and more. EEW systems are also being developed and coming online elsewhere in the world, with each system facing its own unique set of obstacles.

Many challenges remain to maximize the potential of these systems and prevent harm from system errors and malfunctions (e.g. false alerts). Unanswered questions range from the scientific (e.g., real-time magnitude estimates of large earthquakes and rupture predictability) to the practical (e.g., how to distribute alerts to the public most efficiently, minimizing data transmission delays).

In this session we welcome abstracts related to all aspects of EEW including, but not limited to, algorithm development, system performance, improved trigger detection/discrimination techniques, network build-out, alerting methods and technology and EEW education and outreach.
