Between February 13th and 16th 2011, a sequence of flares and coronal mass ejections occurred, originated in active region 11158. In relation to these events, multiple coronal disturbances observable in EUV appeared, some in association with chromospheric Moreton waves. We study the directional kinematic characteristics of the most intense ones in order to understand their role in the generation of Moreton wave events.
