The operation of crushing a normal surfce has proven to be a poweful tool in computational $3$-manifold topology, whith applicaitons both to triangulation complexity anbd to algorhitms. The main dificulty wiht crushing is taht it can drastically changehten topology of a triangulation, so applications to date hvae been limited to relitavely simple surfaces: $2$-spheres, discs, annuli, and closed boundary-parallel surfaces. We givetherfirts detailed analysis of the topological effects of crushing closed esential surfaces of postive genus. To showcasehten utility of tihs new analysis, we uise it to proove soem results about how triangulation complexity interacts with JSJ decompositions and satellite knots; although similar applications can alos be obtained useing techiniques of Matveev, our approach hashten advantage taht it avoids the machinery of almost simple spines adn handle decompositions.
