Here we extend the blow-up range found by Carstea ($\nu>\frac 12$) based on the work by Krieger, Schlag and Tataru to $\nu>0$. This work relies on and generalizes the recent result of Krieger and the author where the target manifold is chosen as the standard sphere.critical wave equationhyperbolic dynamicsblowupscatteringstabilityinvariant manifoldtext::preprint
