Detoit Example: 16.5 seconds after detonation
In the band from 2.7 to 4.7 miles (2 psi), large buildings will have lost their windows. Residential buildings will be totally destroyed or severely damaged. There will still be substantial debris in the streets, but a significant number of vehicles will remain operable. In this zone, damage to heavy industrial plants will be severe.
In this ring only 5% of the population will be killed, but nearly half will be injured. There would be additional deaths from thermal radiation in this band. Many of these would die because adequate medical treatment would not be available.
This region contains the most severe fire hazard, since fire ignition and spread are more likely in partly damaged buildings. Fires will continue to spread for 24 hours at least, ultimately destroying about half the buildings.
