2. ITIS023 Mercure Basin Fault ITCS038 Remediello-Mormanno Composite source DISS reports that the seismogenic potential associated to such faults is Mw 6.4.

3. Source Model – Mercure Basin Fault Approximated 1D wave-propagation (ray theory) Lenght=22km ; Width=13km Strike, dip, rake= 335°, 60°, -90° Top depth = 1 km Mw=6.4 Slip distribution = Heterogeneous (with 2 main patches of slip) rupture velocity = 0.8 Vs

5. DSM Synthetic seismograms are computed through a modified versione of the stochastic method proposed by Boore (1983) for point source model: Gaussian noise is modulated with acceleration envelopes, computed solving the rapresentation theorem for an extend source The amplitudes are scaled applying a Reference Fourier spectrum, whose parameters (corner frequency and distance from the fault ) are inferred from the modelling of the extend source. = X  Random Noise Deterministic Envelope IFFT (point-source-like Reference Spectrum) Synthetic Seismogram
