- Abstract
- This study involves the development of a general computer model for calculating the initition and spread of fire from a nuclear attack on an urban area and its application to the cities of Detroit, Albuquerque and San Jose. Each city is represented by several hundred tracts which are distinguished from one another in terms of the size and composition of the built up area and the width and length of the firebreaks to the built up areas in adjacent tracts. Two codes are employed to evaluate the fire damage; the first computes the percent of buildings ignited in each of the several categories of built up area used to represent the city as a function of distance from ground zero; the second computes the spread of fire by radiation and firebrands witin and between tracts as a function of time. Pictorial illustrations were generated for each of the cities showing the percent of buildings undamaged by fire in each of the tracts at 0, 1, 3, 10 and 28 hours after a 5 MT burst. Volume 1 of the report contains a description of the development of the computer model and the procurement of data while Volumes 2, 3 and 4 indicate the fire damage to the cities of Detroit, Albuquerque and San Jose, respectively, from the 5 MT burst.
