Permanently Instrumented Field Sites Database, UCSB



Published on


Search, Sort and Compare Field Sites Waveform Data Stored in the Project Warehouse!


The NEES@UCSB facility consists of permanently instrumented geotechnical test sites designed to improve our understanding of the effects of surface geology on strong ground motion.

Click the View Database button to browse, search, sort, plot and compare the UCSB Field Sites waveform data stored in the NEEShub Project Warehouse.

How to Use the Data View to Explore Field Sites Waveform Data

When you click the View Database button, you will be able to browse, search, explore and plot Field Sites Waveform Data

  • Explore by Event, Station, Magnitude, Latitude, Longitude, Depth, Time and Azimuth
  • Use Map to locate Stations and Events
  • Click on the Waveform Data column for any Event to View Waveform Data, where you can select one or more Channels to plot and compare with the inDEED waveform visualization tool.

Here is an example showing how to find valuable information about El Mayor (magnitude 7.2) in the Project Warehouse with a few clicks!

Layout Data View for all 8 Field Sites

This data view displays station layout and site information for all eight UCSB permanently instrumented field sites . The data was pulled from the NEES@UCSB web site.

The instrumentation at these sites includes surface and borehole arrays of accelerometers and pore pressure transducers designed to record strong ground motions, excess pore pressure generation and liquefaction that occurs during large earthquakes. An instrumented structure is also monitored to improve our understanding of soil-foundation-structure interaction (SFSI) effects. See the NEES@UCSB web site for more information.

You can access the SEED Reference Manual (Standard for Exchange of Earthquake Data) for information about the international standard format for exchange of digital seismological data. The appendix "Channel Naming Convention"defines the meanings of the channel characters used in the Site Channels data view.
