Impact of Hydrothermally Altered Soil on Vegetation as a Tool in Geothermal Exploration,
Abstract
The spectral reflectance of vegetation over the Caldera of Los Humeros is used to locate potential geothermal areas. The ratio of Landsat band 7 to band 5 is found to be an excellent discriminant between anomalous and background trees. A maximum likelihood classification outlines the anomalous vegetation. This is coupled with a criterion to account for bare spot, mud ponds, fumaroles, and other surface manifestations. The result is an outline of the area with highest level of geothermal activity.
