New Webservice Tools and Updates at the Center for Engineering Strong-Motion Data (CESMD)
Session: Strong-Motion Data Processing and Dissemination: State-of-the-Art and Outlook
Type: Oral
Date: 4/23/2021
Presentation Time: 10:00 AM Pacific
Description:
The Center for Engineering Strong-Motion Data (CESMD), an internationally utilized joint center of the U.S. Geological Survey (USGS) and the California Geological Survey (CGS), provides a single access point for earthquake strong-motion records and station metadata from the CGS California Strong-Motion Instrumentation Program (CSMIP), the USGS National Strong-Motion Project, the USGS Advanced National Seismic System, and other affiliates. The CESMD has developed new tools to facilitate access to strong-motion data and metadata for use in post-earthquake response and scientific and engineering research applications. The Center provides raw and processed strong-motion data via the Engineering Data Center (EDC) and Virtual Data Center (VDC) web portals currently hosting more than 52,000 records with peak ground accelerations greater than 0.1%g from over two thousand earthquakes. This presentation will highlight updates at CESMD and new tools available to the seismic and engineering community for accessing strong-motion datasets at CESMD. These updates include: 1) an initiative to merge the waveform databases at the EDC and VDC, 2) new access options to station metadata, earthquake information, and strong motion records via either the web-interface or a web-services client, 3) an interactive map interface to facilitate easy user viewing and access to earthquake, station, and record information, 4) development of a new web application tool for data conversion, 5) efforts to standardize the format of waveform records in the database into a consistent format, 6) a modernized compilation of seismic station site geology, measured or inferred Vs30 values, shear-wave profiles, NEHRP site class, and available structure instrument deployment schematics, and 7) a special studies page with several research topic-specific ground motion datasets that offer uniform processing of records from a variety of sources.
