Abstract
Abstract Following the 2019 Ridgecrest, California, earthquake sequence, we compiled ground-motion records from multiple data centers and processed these records using newly developed ground-motion processing software that performs quality assurance checks, performs standard time series processing steps, and computes a wide range of ground-motion metrics. In addition, we compute station and waveform metrics such as the time-averaged shear-wave velocity to 30 m depth (VS30), finite-rupture distances, and spectral accelerations. This data set includes 22,708 records from 133 events from 4 July 2019 (UTC) to 18 October 2019 with a magnitude range from 3.6 to 7.1. We expect that the rapid collection and dissemination of this information will facilitate detailed studies of these ground motions. In this article, we describe the data selection, processing steps, and how to access the data.
