Corrected entry: The explosion of a failed Extremis subject is so strong it vaporizes living organisms in the blast radius along with collateral damage (as shown at the Chinese Theater). In Tennessee, the site of a similar incident, it is shown that the crater of the explosion is a few feet from the corner of two walls. The walls, for some reason, were not obliterated even though the explosion was strong enough to destroy everything else.

Correction: There is severe damage to the walls in Tennessee, and if you watch the Chinese Theater scenes you see that all of the walls surrounding the blast area are intact. The Extremis explosion is a heat-related blast, the bulk of the damage is to organic tissue.
