Earthquake Early Warning Optimization and Efficacy
Several elements contribute to the optimization of an Earthquake Early Warning (EEW) system’s performance, including: the design of the network, choice of sensors, algorithm refinement and means of communications. The processing of data and the accuracies and latencies this introduces also require analysis to ensure warnings are timely and meaningful. For example, the inclusion of site amplification in estimating intensities and the extent of the potentially impacted region should improve the accuracy of the EEW system; it may, however, slow the distribution of alerts. Additionally, EEW systems can only be effective if people and systems respond appropriately. Technical recipients must have automated systems in place to initiate protective measures, and people need to take safe response actions, such as to Drop, Cover and Hold on. To establish the necessary culture of awareness and preparedness, EEW organizations must work with others, including emergency measures organizations, to ensure a broad, consistent and authoritative EEW education and outreach effort. Such initiatives should include engagement with critical infrastructure operators and take special care to address particularly vulnerable populations, such as low income, new immigrants, Indigenous and elderly.
This session invites abstracts on all aspects of optimizing EEW systems, including sensor and communication developments, optimizing methodologies and system assessment and abstracts related to Education, Outreach and Engagement for EEW.
