general relativity - Can gravitational waves escape from inside of black holes?

I understand that light cannot escape from inside of an event horizon because the spacetime curvature is too warped for photons to escape. On the other hand, gravitational waves are ripples of spacetime curvature itself (as opposed to light being IN the spacetime), so if there is some internal dynamical structures inside of blackholes (forget about no hair theorem for the moment) that produce gravitational waves, can those gravitational waves escape from inside of event horizon?
