Fortran and Matlab codes

Empirical Green’s function (EGF) method to calculate Apparent Source Time Functions (ASTFs)

A Fortran code and Gnuplot graphics scripts are available to perform the inversion and to automatically visualize the results.

Method published in: V. Plicka, F. Gallovic, J. Zahradník, A. Serpetsidaki, E. Sokos, N. Vavlas, A. Kiratzi (2022). The 2022 Samos Mw7 earthquake: Source model depicting complexity and rupture directivity, Tectonophysics 843, 229591, https://doi.org/10.1016/j.tecto.2022.229591. PDF PDF-Suppl
