    Self-sustained vibrations in volcanic areas extracted by Independent Component Analysis: a review and new results by E. De Lauro, S. De Martino, M. Falanga, M. Palo

    Published 2011-12-01
    “…A volcano is a complex system where a fluid source interacts with the solid edifice so generating seismic waves in a regime of low turbulence. Although the complex behavior escapes a simple universal description, the phases of activity generate stable (self-sustained) oscillations that can be described as a non-linear dynamical system of low dimensionality. …”

    Analysis of the simultaneous influence of the horizontal seismic load components on buildings by Stevanović Dušan, Salatić Ratko, Bubalo Andrej

    Published 2022-01-01
    “…Earthquake records indicate that earthquake motion is an irregular oscillatory soil movement as a consequence of the heterogeneity of the soil material, as well as due to reflection, refraction, and interference of seismic waves. The trajectories of soil particle movement during an earthquake are proven to be chaotic, so the approximation of seismic effects by a simplified collinear model is very rough from an engineering point of view. …”
