event: an identifier ID of the generated scenario
a_parameter: proportionality parameter controlling the strength of the high-frequency source radiation
Vr: rupture velocity [km/s]
slip_real: realization of the (random) slip distribution with asperity prescribed in the middle, on one or the other side, or both sides, (i.e., one of the 8 slip distributions)
nucl_alongstrike: position of nucleation point along strike of the fault [km] (0 corresponding to NW)
nucl_updip: position of nucleation point along dip of the fault [km] (0 corresponding to the top of the fault)
fault_size: area of the fault rupture [km2]
stress_drop: stress parameter or stress drop [MPa] aggregates parameters according to Eq. (7) in Čejka et al. (2024), i.e. it is a combination of rupture velocity, rupture size and scalar seismic moment.

Note: strike/dip/rake angles to 155°/45°/85°, 
latitude and longitude of the fault center is 42.7063° N, 13.2532° E,
and the scalar seismic moment is set to 2.6x10^18 N*m (Pizzi et al., 2017; Gallovič et al., 2019).
