The JSJ decomposition encodes the automorphisms and the virtually cyclic splittings of a hyperbolic group. In this paper, the author studies the automorphisms of a hierarchically hyperbolic group that satisfies some weak acylindricity conditions. To study these automorphisms he constructs an object that can be viewed as a higher rank JSJ decomposition. This construction is studied in the case of right angled Artin groups.
