We present a detailed numerical study of solutions to the Zakharov-Kuznetsovequation in three spatial dimensions. The equation is a three-dimensionalgeneralization of the Korteweg-de Vries equation, though, not completelyintegrable. This equation is $L^2$-subcritical, and thus, solutions existglobally, for example, in the $H^1$ energy space.  We first study stability of solitons with various perturbations in sizes andsymmetry, and show asymptotic stability and formation of radiation, confirmingthe asymptotic stability result in \cite{FHRY2020} for a larger class ofinitial data. We then investigate the solution behavior for differentlocalizations and rates of decay including exponential and algebraic decays,and give positive confirmation toward the soliton resolution conjecture in thisequation. Finally, we investigate soliton interactions in various settings andshow that there is both a quasi-elastic interaction and a strong interactionwhen two solitons merge into one, in all cases always emitting radiation in theconic-type region of the negative $x$-direction.
