A method and system of processing seismic data includes acquiring
three-component seismic data and combining horizontal components of the
three-component seismic data to obtain a merged horizontal component.
Frequency spectra are determined for the acquired three-component seismic
data. A ratio of a vertical component of the seismic data to the merged
horizontal component is determined. A V/H integration-measure is obtained
from the integration of the area bounded by a selected minimum-amplitude
value and the amplitude values greater than the selected
minimum-amplitude value and the V/H integration-measure is stored in a
form for display.
