There is a big BOOM in your home, upon inspection you find 1/3 of your home is gone, your first thoughts are?

You are sleeping, bathing, watching TV, etc, and an earsplitting boom literally shakes your home; pictures fall off the wall, décor knocked from shelves. When you go to the direction of the boom to investigate, you find ⅓ of your home has been blown away; there isn’t anything bigger than a phonebook you can see, it looks like the place has been shredded. Nothing is burning, it is just gone, blown away. What is your first thought?
