Web1 dec. 2012 · These anomalies are found to maximize across the epicentre in the direction opposite to the tsunami propagation suggesting that the large atmospheric/ionospheric disturbances are excited in the region where tsunami does not travel. Acoustic-gravity waves, Ionosphere/atmosphere interactions, Tsunamis Issue Section: Gravity, geodesy … WebA physical mechanism explaining the ionospheric pre-seismic anomalies generated from the ground to the ionosphere were formulated within the framework of the Lithosphere-Atmosphere-Ionosphere Coupling (LAIC) model. The detailed classification of these anomalies was presented for different ionosphere regions, and the signatures of these …
