                         ionospheric heights possesses the ability to perturb the 
                         ionosphere. Detailed modelling investigation considering 1-D 
                         dissipative linear dynamics, however, indicates that the magnitude 
                         of ionospheric perturbation strongly depends on the magnetic field 
                         inclination. Physics-based SAMI2 model codes have been utilized to 
                         simulate the ionosphere perturbations that are generated due to 
                         the action of the vertical wind perturbations associated with the 
                         seismic infrasound. The propagation of the seismic energy and the 
                         vertical wind perturbations associated with the infrasound in the 
                         model has been considered to be symmetric about the epicentre in 
                         the north-south directions. Ionospheric response to the infrasound 
                         wind, however, has been highly asymmetric in the model simulation 
                         in the north-south directions. This strong asymmetry is related to 
                         the variation in the inclination of the Earth's magnetic field 
                         north and south of the epicentre. Ionospheric monitoring generally 
                         provides an efficient tool to infer the crustal propagation of the 
                         seismic energy. However, the results presented in this paper 
                         indicate that the mapping between the crustal process and the 
                         ionospheric response is not a linear one. These results also imply 
                         that the lithospheric behaviour during a seismic event over a wide 
                         zone in low latitudes can be estimated through ionospheric imaging 
                         only after factoring in the magnetic field geometry.",
