KGS--Yuma Project


This web site has been created in support of the Kansas Geological Survey's Yuma Project. For information on this project, please contact Rick Miller, project investigator.

Data and Information available online

Update message archive

To keep everyone as current as possible on the status of KGS work on the site characterization at the SWTR site on YPG, this web page will be frequently updated with data and status reports. I will send everyone on the YPG list an e-mail when the web page has been updated. We are beginning to produce large chunks of processed data and need to begin planning the movement of this data across several platforms and institutions. Hopefully using this web page in the prescribed fashion will provide the necessary heads up and status reports critical to streamlining the data transfer activities.--Rick Miller

1-D Data Files

1-D data file for station 1030. Included are Vp (refraction), Vp (tomography), Vs (surface wave inversion), Qp (2 x Qs), Qs (Qr (z) assuming 1/2 wavelength criteria), Qr (f) (surface wave inversion). These data were extracted from the 2-D data set currently being geostatistically analyzed for posting tomorrow.

Surface Elevation of the Yuma Site

Contour maps, block diagrams, and
data to download are available from this page.

Map of Acquisition Lines

This schematic shows the survey lines identified by their number designations. These numbers are consistent with the field notes, processed station numbers, and GPS data.
