Data Types
- Time Series data
- Continuous seismic instrument recordings from thousands of stations worldwide. This is the primary NSF SAGE archive.
- Metadata
- Includes information such as recording instrument characteristics and data quality; this is generally used to determine the time series data to request.
- Event data
- Catalog of 4 million+ events, this is useful in determining the timeframe for retrieving useful data.
- Assembled data
- Discrete collections of waveform data, generally recorded over a period of weeks or months. Assembled data are often active source, meaning that they include artificial seismic events such as explosive blasts intended to seismically map a given region.
- Data products
- Calculated datasets providing a higher-level view of the raw data. For example, the GMV product is an animated map showing ground movement across hundreds of stations during an earthquake.
- Historical data
- Scanned seismograms and other information from pre-digital sources.
Data Delivery
- Web Services
- This is the base delivery mechanism for most NSF SAGE data. It can be accessed directly, but a variety of convenient wrappers are available.
- Application Programming Interfaces
- APIs are available via Java, Matlab, and Python libraries, as well as command line fetch scripts.
- Web Tools
- Downloadable Software
- Other Data Centers
- How to Cite Data Sources
Time Series Data
- Web and Email-based Tools
- BREQ_FAST takes requests via email and delivers data via FTP/HTTP.
- Wilber3 offers a rich UI for acquiring data related to a given seismic event.
