The understanding of the earthquake source experienced a significant progress when it was recognized that their occurrence is tightly linked to tectonic activity (Süss, 1873, 1875). Indeed, the most prominent seismoactive zones are found along the midatlantic ridges, the mountain belts and along major fault systems in the continental plates, i. e., zones with intensive [...]

The simplest description of the seismic source is the concept of a point source (see Fig. 1). Even though in contrast with common physical and geological concepts the point source is still used for certain purposes, such as earthquake geographics or earthquake statistics. The parameters for the point source essentially are:
