Exciting news! We're transitioning to the Statewide California Earthquake Center. Our new website is under construction, but we'll continue using this website for SCEC business in the meantime. We're also archiving the Southern Center site to preserve its rich history. A new and improved platform is coming soon!

Cloud Computing and Big Data – Ridgecrest DAS dataset in the Amazon Cloud (s3://scedc-pds us-west-2 region.)

- To support the SCEC community’s exploration of DAS datasets, and to develop use cases for community standards in its archival, the SCEDC is hosting 30 days (2020/06/23 - 2020/07/29, ~4TB) of the Ridgecrest DAS dataset in its AWS Open Dataset. (s3://scedc-pds/Ridgecrest_DAS). The data, sampled at 250 Hz, is in SEG-Y format and organized into hourly files.

- We will highlight a Jupyter notebook demonstrating how to retrieve DAS data, and how to window and down sample data using AWS services.
