"The project focused on new methods to simulate strong ground motions for past and future earthquakes. Two main methods were developed for forward broadband modeling of finite-extent seismic sources: (i) integration method based on representation theorem"@en . "2009-01-15+01:00"^^ . "Understanding damaging effects of past earthquakes, and simulating strong motions for future events is a challenging problem. The proposing team can contribute to its solution both theoretically and practically (seismic stations of the Charles Universityoperate in Greece since 1997). The main research goal is to develop new mathematical methods for the forward strong-motion prediction due to finite-extent source models. Several methods, combining deterministic and stochastic features are suggested. Theground motions will be computed for selected sites, or stations, but also for areas (expected ground-motion maps). Free parameters will be tuned by comparisons with observed data, such as the acceleration time series, response spectra, macroseismic mapsand attenuation curves. The most critical aspect of the strong motion simulation is realistic description of the fault heterogeneity. That is why, in parallel with forward simulations, new methods of the finite-source slip inversion will be also"@en . . "0"^^ . . "Neuvedeno."@en . .
