translation.en: Now, in a shelter in an urban area means you have to be either in a basement as deep as possible, or you have to be on a floor -- on a high floor -- if it's a ground burst explosion, which it would be, higher than the ninth floor. So you have to be tenth floor or higher, or in the basement.
