The Southern California Earthquake Data Center (SCEDC) is the primary archive for the Southern California Seismic Network, hosting its earthquake catalog (1932-present), and waveform archive. A copy of these assets is also available in the AWS cloud. (s3://scedc-pds us-west-2 region.) This S3 bucket also contains one month of distributed acoustic sensing (DAS) data from the Ridgecrest region for a 10 km array.

The large timespan of this data alongside consistent curation of the event catalog makes it ideal for many different analyses and research projects. In this poster we present new or updated tutorials, many of which exist as Jupyter or Google Collab notebooks to help r...esearchers use and explore the SCEDC archive.

- How to use the clickable station map as a data discovery tool in your research.

- How to access catalog processing status, important when examining the Ridgecrest sequence which includes events that are not yet manually reviewed

- How to retrieve DAS data hosted at s3://scedc-pds, convert to strain rate, compare modeled earthquake traveltimes against observed DAS recordings, and compute noise cross correlations from continuous passive DAS data.

- How to process seismic data using cloud native AWS services.

- How to retrieve event, phase picks, station, and waveform data from SCEDC through various methods
-- MATLAB (irisFetch and/or GISMO)
-- PySTP
-- FDSN webservices
