Northern California Earthquake Data Now Available in AWS Cloud

Description: 

The Northern California Earthquake Data Center (NCEDC) is a permanent archive and distribution center for multiple types of digital data related to earthquakes in central and northern California. The NCEDC is located at the university of California, Berkeley, and has been accessible to users via the Internet since mid-1992. Time series data mainly come from broadband, short period, and strong motion seismic sensors, as well as from other geophysical instruments. Earthquake catalogs include origin time, hypocenter, magnitude, moment tensor, focal mechanisms, phase arrivals, codas, and amplitude data. Metadata and instrument response for seismic sites are accessible in various formats for all data channels archived at the NCEDC. The NCEDC also provides support for earthquake processing and archiving activities of the Northern California Earthquake Management Center, a component of the California Integrated Seismic Network (CISN). Data holdings currently consist of more than 184 TB of data encompassing 29 networks and 2,640 stations. In 2023, the NCEDC archive became part of the AWS (Amazon Web Services) Open Data Sponsorship Program and all of its data are now mirrored in the cloud (s3://ncedc‐pds; us‐east‐2 region). Tutorials (https://ncedc.org/db/cloud/getstarted-pds.html) and data structure (https://ncedc.org/db/cloud.html) are available to facilitate user access to this public data set. This allows the NCEDC to leverage AWS cloud infrastructure and provide users the ability to provision gigabit connections to the archive as well as take advantage of the computational resources offered by AWS.
