Seismic risk mapping

  • Jixel offers a service that allows the automatic identification of the seismic risk of a site, obtained through stratigraphy of soil, of simulated and of real earthquakes. The service is based on the SHAKYGROUND software, developed by IES and capable of simulating the effect of an earthquake on an urban or industrial area. SHAKYGROUND has been tested in real situations, so to verify the correctness of the simulations outcomes and the measured damages.
    The service generates seismic risk maps on the basis of Vulnerability and Exposed Value, starting from the risk values obtained from the SHAKYGROUND outcomes.
  • The simulations outcomes are the seismological basis for the design of anti-seismic buildings and for the optimization of land planning. The SHAKYGROUND characteristics can identify in advance sites that are not suitable for building, and define more easily Emergency Plans in case of earthquakes. They also can guide the experts on the buildings dimensioning. The outcome spectrums generated by SHAKYGROUND may be directly compared to the spectrums foreseen by the law (e.g. EC8, US Building Code).
    SHAKYGROUND is also available as a software suite for Microsoft Windows.
