Resumen:

In this paper an alternative vision, based on the Chaos Theory, for the analysis of soils systems oscillating under seismic forces is described. The topological tool, Recurrence Plots RPs, enables recognition and treatment of accelerations recorded in seismological stations located on soil deposits. The chaotic attributes obtained from RPs are interpreted for determining the natural period of vibration. This dynamic non-linear characterization could help in the evolution or reinterpretation of some partially understood aspects of seismic phenomena.
