CSN-LAUSD Network: A Dense Accelerometer Network in Los Angeles Schools

Abstract

Abstract The Community Seismic Network-Los Angeles Unified School District is a network of 300 low-cost microelectromechanical systems accelerometers located in schools in the Los Angeles, California, region. They are capable of accurately recording strong motion up to ±2g and are sufficiently spatially dense that they provide unaliased measurements of strong motions up to 1 Hz following a major earthquake. They are used to provide state-of-health monitoring for the schools and surrounding communities to guide the emergency response. As a research tool, they can be used to provide estimates of the site response at the schools and, therefore, provide a much denser set of site responses for ground-motion prediction than is currently available.
