Fusion frames are widely studied recently due to its many kinds of applications. In this paper we focus on the erasure of a fusion frame; we use a bounded linear operator to equivalently characterize a given fusion frame to be robust to an erasure of any numbers of elements; it turns out that our result is more general and covers some important results previously obtained by Asgari, Casazza, and Kutyniok. We also present a more general equality result for any fusion frame (not restricted to be tight), which improves the fusion version of a theorem obtained by Li and Sun.
