Is there a word that describes a natural phenomenon which rarely occurs, yet when it does so, it causes widespread destruction?

  • What does high intensity mean here? What sorts of events are you thinking of? You mean like supernovae or climate-changing meteor impacts or lunar eclipses? – tchrist Jun 8 '14 at 15:56
  • The word is catastrophe, natural catastrophe, or natural disaster. – RegDwigнt Jun 8 '14 at 15:57
  • ekpyrosis: the destruction of the universe by fire -ekpyrotic – Third News Jun 8 '14 at 20:29
  • @tchrist exactly the sort of events you mentioned – Rudstar Jun 10 '14 at 8:55

Some words that come to mind are volcanic, eruptive, cataclysmic, orgasmic and paroxysmal.
