The properties of traveling ionosphere disturbances (TID) (their horizontal sizes are 1–4 thousand kms, excesses of a background are 15–30 %), formed in F2 layer as a result of strong earthquake in time of heliogeophysical perturbations are explored. The irregularities arise 10–15 h before earthquakes and move horizontally with a transonic speed on distances of a few thousand kms up to round—the - world trajectories focused approximately along an arc of a major circle, transiting above epicenter region. Information of spent examination was caused by spatial - time differences of dynamics of F2-layer of an ionosphere in time of the heliogeophysical disturbances from dynamics of quasicausative seismic macro-scale ionosphere irregularities.
