Summary
The projective seismicity of a single earthquake results from the local seismicity of the concerned quake. For the focal region a spherical and a cylindrical model are discussed. The volume of the focal region is identified with the focal volume. For calculation of the radius of both the sphere and the cylinder a common formula based on the Båth and Duda relation between the focal volume and the magnitude of an earthquake is used.
