  • An analysis of the neotectonic activity and the current stress state of the eastern border of Madrid Basin has been carried ont using structural-methods (fault population analysis), as well as seismological methods.

    Two stress tensors have been established:

    - Tensor 1: with a N150ºE shortening trend, characterized mainly by strike-slip faults. This tensor corresponds to the "Guadarrama" stress field (Capote et al., 1990), wihch causes the Central System structure; dated middle Aragonian-lower Pleistocene in the eastern border of Madrid Basin (Muñoz Martín, 1993).

    - Tensor 2: dated post-Iower Pleistocene, with a N150°E extension trend, characterized basically by normal faults.

    Actual stress tensor deduced focal mechanisms by the seismological method is compatible with the paleostress field deduced for the middle-Iower Pleistocene (tensor 2).
