Parameter Short explanation Stress drop is associated to the difference between the stress across a fault before and after an earthquake and it is usually included between 10 bar and 100 bar Medium density density of the rocks around the source; generally between 1.5 g/cm3 and 2.8 g/cm3 S-waves average velocity Vs around the seismic source Earthquakes depth depth for which the sensitivity is calculated Minimum number of detecting stations 1 for detection threshold, >3 for location threshold Signal to noise ratio for detection limit limit for an impulse to be visible on the seismogram Magnitude steps increments in the minimum detectable magnitude research Map extension (Percent of the station distances,>0) the map extension of the grid is defined as the maximum distance between the stations times a percent of the same distance for X and Y separately Grid point number numbers of the grid points along X and Y. The program running time increases as the square of this number.
