Optimizing Earthquake Early Warning Performance: ElarmS‐3

  author={Angela I. Chung and Ivan H. Henson and Richard M. Allen},
  journal={Seismological Research Letters},
The University of California Berkeley’s (UCB) Earthquake Alert Systems (ElarmS) is a network-based earthquake early warning (EEW) algorithm that was one of the original algorithms developed for theU.S. west-coast-wide ShakeAlert EEW system. Here, we describe the latest update to the algorithm, ElarmS v.3.0 (ElarmS-3 or E3). A new teleseismic filter has been developed for E3 that analyzes the frequency content of incoming signals to better differentiate between teleseismic and local earthquakes…
