1 Mt Surface Blast: Pressure Damage
Key:
 |
12 psi (pounds per square inch) Radius: 1.7 miles [Note: The outside edge of this shaded area represents the 12 psi ring. Blast pressure within the ring is greater than 12 psi; blast pressure outside the ring is less than 12 psi.] At the center of the ring lies a crater 200 feet deep and 1000 feet in diameter. The rim of this crater is 1,000 feet wide and is composed of highly radioactive soil and debris. Nothing recognizable remains within about 3,200 feet (0.6 miles) from the center, except, perhaps, the remains of some buildings' foundations. At 1.7 miles, only some of the strongest buildings -- those made of reinforced, poured concrete -- are still standing. Ninety-eight percent of the population in this area are dead. |

5 psi Radius: 2.7 miles Virtually everything is destroyed between the 12 and 5 psi rings. The walls of typical multi-story buildings, including apartment buildings, have been completely blown out. The bare, structural skeletons of more and more buildings rise above the debris as you approach the 5 psi ring. Single-family residences within this this area have been completely blown away -- only their foundations remain. Fifty percent of the population between the 12 and 5 psi rings are dead. Forty percent are injured. |
