Inverting full waveforms into 1D seismic velocity model of the upper crust by neighborhood algorithm - Corinth Gulf, Greece

Popis výsledku v původním jazyce

We investigated inversion of full waveforms into formal 1D velocity models. 'Formal' means that the models are primarily intended to simulate complete seismograms close to real records, rather than to reflect the true crustal structure from the geological point of view. The method is demonstrated for a magnitude M-w 5.3 earthquake (centroid depth of 4.5 km), recorded at 8 three-component stations in the Corinth Gulf region, Greece, spanning the epicentral distance range from 15 to 102 km, and frequencyrange from 0.05 to 0.2 Hz. The forward problem was solved by the discrete wavenumber method, while the inversion was performed with the neighborhood algorithm. As such, not only the best-fit models, but also suites of the models almost equally well satisfying data were obtained. The best resolution was found in the topmost similar to 10 km. Extensive testing of the model parametrization enabled identification of the most robust features of the solution. The P- and S-wave velocities are c
