On 29 March 2014, a Moreton wave was detected with very high cadence with the Halpha Solar Telescope for Argentina (HASTA). The wave was associated with an X1 flare in AR 12017 and a coronal mass ejection (CME). We analyze the connection between the Moreton wave and the EUV signatures observed with the Atmospheric Imaging Assembly onboard the Solar Dynamics Observatory (SDO/AIA). We study the kinematics of the wave fronts along several directions using stack plots and find links between the features observed in the chromosphere and low corona at various wavelenghts. We also analyze the association between the waves and the CME. To explain the propagation of the observed EUV wave fronts and their chromospheric traces, we propose a 3D geometrical model based on an expanding and outward-traveling coronal shock-wave front that intersects the solar sphere. Finally, we discuss the particular conditions of the coronal medium and the possible origin of the shock wave.
