However, Type II supernovae dump the vast majority (99%) of their energy into neutrino radiation. Moreover, the extremely high energies of supernova neutrinos (MeV range) increases their interaction cross-section as well as the damage they can do when they do interact. If a supernova (or hypernova) were to occur close enough to Earth it could cause a mass extinction due to neutrino radiation alone. Consider, supernova 1987A radiated so many neutrinos that it increased the neutrino flux at Earth by 10,000x compared to the Solar flux.
