The method combines the use of the logic decision tree and the empirical relationship between the Tectonic Stress Index, TSI, and a series of K in situ values obtained from an extensive database. The decision tree considers geological and geophysical factors affecting stress magnitudes both on the regional and local scale.


Emphasis has been placed on the influence of mineralogy and fabric on the strength and deformation properties, and Please select Ok if you would like to proceed with this request anyway. Since La Laguna soils show similar engineering-geological characteristics to other widely distributed tropical volcanic soils, a review has been made of the different hypotheses which attempt to explain the abnormal properties of these soils.
