I actually live close enough to the place where the explosion happened that I heard a loud noise outside when it happened. I thought it was something my dad was doing outside because he was working with the tractor, but it wasn't. Some people felt their houses shake and thought it was an earthquake. Later on when we were watching the news, my dad told me that his boss asked him to work near the place where the explosion happened, but he turned down the job because he had work to do at home. thank god that he said no to the job!
