These huge bubbles arise from many supernovae occurring close together in both space and time and are called "superbubbles." The supernovae are correlated because stars tend to form in clusters and massive stars live for a relatively short time. Thus when the massive stars supernova, they are still relatively close together and do so within a few hundred thousand years of each other (which is a short time compared to Galactic timescales).
