5. Conclusion

[17]  The authors consider the analysis performed as a confirmation of two independent hypotheses. The suggestion on triangle trajectories is confirmed by the fact that in a "proper moment and proper place" there appear positive irregularities preceding corresponding earthquakes. On the other hand, joint consideration of the observations at the ground-based stations and on board Mir makes it possible to state that the irregularities preceding earthquakes are detected by two independent methods. The irregularity parameters agree well with the data of 38 cases of macroirregularity detection described earlier. Finally, the data obtained may be considered as an independent confirmation of the hypothesis that an irregularity has "sharp" edges. The earlier results of tomography processing of the data of navigation satellites [Kunitsin et al., 1995] also indicated this fact.
