Abstract

The Community Seismic Network (CSN) is a cloud-based, strong-motion network of seismic stations deployed in the greater Los Angeles area. The sensors report three-component acceleration time series data and peak acceleration scalar data for use in assessments of earthquake shaking intensity in buildings and on the ground level, monitoring structural health of instrumented buildings, zonation maps of future shaking potential, and the ShakeAlert earthquake early warning system. The hardware and software behind CSN's client and server architecture are described, as well as network subarrays deployed at Los Angeles Unified School District campuses, the NASA-JPL campus, and in mid-rises and high-rises.

Additional Information

The Community Seismic Network is the product of years of work by many people who have made up the CSN team over the years. The author is a part of this team, and in representing this team wishes to acknowledge their past and ongoing contributions to the CSN project. The current CSN team members are Robert Clayton (Seismological Lab; California Institute of Technology), Thomas Heaton (Department of Mechanical and Civil Engineering, and Seismological Lab, California Institute of Technology), Richard Guy (Department of Civil and Environmental Engineering, University of California, Los Angeles; and Seismological Lab, California Institute of Technology), Julian Bunn (Center for Data-Driven Discovery, Division of Physics, Math and Astronomy, California Institute of Technology), Filippos Filippitzis (Department of Mechanical Engineering, University of Western Macedonia, Kozani, Greece; and Department of Mechanical and Civil Engineering, California Institute of Technology), Yousef Bozorgnia (Department of Civil and Environmental Engineering, University of California, Los Angeles) and Ertugrul Taciroglu (Department of Civil and Environmental Engineering, University of California, Los Angeles). The CSN team is grateful to Caltech, UCLA, the Conrad N. Hilton Foundation, and Computers & Structures Inc., the Gordon and Betty Moore Foundation, and the National Science Foundation for providing support for the Community Seismic Network over the past decade.
