PROBLEMS OF GEOCOSMOS

concentration can be observed during ionosphere storms at the transitional and low latitudes; as well as at the
midlatitudes in the early stages ionosphere storm, if this storm begins at a day time.
CONCLUSION
The above reviewed situations demonstrate that diagnostics of seismic TIDs is quite possible in many
cases, as there are essential differences in the character of time and spatial changes allowing us to distinguish
these disturbances from perturbations of solar and magnetosphere origin. However data configurations that are
submitted in figs. 1~3, are not possible for all earthquakes. One of the reasons is in actual properties of a
network of ionosphere stations - nonuniform spatial arrangement and, naturally, only on land. Other difficulties
are the detection of TIDs on the background of other disturbances in the ionosphere. It is represented that this
short-term harbinger could be the essential block in blanket algorithm of the seismic-ionosphere forecast.
