  We study the leading (LO) and the next-to-leading order (NLO) stability of
multipole perturbations for a static dielectric M2-brane with spherical
topology in the 11-dimensional maximally supersymmetric plane-wave background.
We observe a cascade of instabilities that originates from the dipole (j=1) and
quadrupole (j=2) sectors (the only unstable sectors of the LO) and propagates
towards all the multipoles of the NLO.
