Abstract
The Pacific coast of the contiguous United States hosts the highest seismic risk in the country due to the intersection of high‐seismic hazard and the high densities of population and infrastructure. The regional seismic networks in Washington, Oregon, Nevada, and California have operated for many years and have collected long catalogs and large amounts of seismic waveform data in a variety of formats, including digital records. These data are available for engineering purposes and research into earthquakes, other natural and man‐made seismic sources, and the Earth’s structure. The West Coast networks are closely coordinating as they embark on the implementation of West Coast ShakeAlert, an earthquake early warning system.

The authors thank our partners in earthquake reporting at the U.S. Geological Survey (USGS) regional networks, as well as their and our staff members who ensure that the seismic stations are operating, the data are flowing, and the earthquake information and data are being disseminated. The authors are also grateful for the financial support of our real‐time earthquake information operations from the USGS (USGS Cooperative Agreement G15AC00023: California Institute of Technology [Caltech], G15AC00042: University of California, Berkeley [UCB], G15AC00052: University of Nevada, Reno [UNR], G15AC00053: University of Oregon [UO], G15AC00054: University of Washington [UW]), and from our state governments (California Governor's Office of Emergency Services [CalOES]: 6012‐2017 [Caltech], 6011‐2017 [UCB]), as well as funds and collaboration from other partner organizations. The development, implementation, and buildout of the West Coast ShakeAlert earthquake early warning (EEW) system have been supported by the USGS (G19AS00034 [Caltech], G19AC00298 [UCB], G19AC00265 [UNR], G19AC00294 [UO], G19AC00297 [UW]), the Gordon and Betty Moore Foundation (Grant Numbers 3023 and 5529 [Caltech], 3024 and 4916 [UCB], 3025 [UW]), and our state governments (CalOES 6172‐2018 and 6142‐2018 [UCB], 6166‐2018 California Geological Survey [CGS]). The authors also thank the editors and the three reviewers, two anonymous and David Oppenheimer, for their enthusiasm for our efforts and their comments and suggestions that contributed to a very much improved article. The authors thank Fabia Terra for producing the figures, and all those who contributed station information to support her work.
