PROBLEMS OF GEOCOSMOS

Proceedings of the 7th International Conference "Problems of Geocosmos" (St. Petersburg, Russia, 26-30 May 2008)
(1) the dipole that consists of a pair of positive and negative potentials at the western and eastern boundaries of
the near-epicentral area (Fig. 3, dip1); (2) the dipole elongated in the meridianal direction for ~1500 km (Fig. 3,
dip2); (3) the point monopole charge that consists of one positive charge at the epicenter (Fig. 3, mono1); (4) the
fulfilled rectangular regions of positive charges (Fig. 3, mono2-mono3); (5) positive charged (equipotent)
straight lines of different directions (Fig. 3, mono4-mono6).
