Abstract
The high-frequency electromagnetic permittivity and attenuation rate were measured in situ in a block of densely welded ash flow tuff compressed uniaxially. For stress changes up to 800 psi, the electromagnetic properties were found to be independent of stress, except where the water content of fractures may have been controlled by aperture changes induced by the compressional loading.
