Remain down until the blast wave has passed and debris
has stopped falling.

A depression in the earth's surface, logs, large rocks, or other
objects provide protection if other cover is unavailable, but only if
immediately adjacent to you. Remember to keep your head toward the
burst when in a ditch or behind a hill. (Figure 1-3.)
