DEVELOPMENT OF "TYPICAL" URBAN AREAS AND ASSOCIATED CASUALTY CURVES.
DIKEWOOD ALBUQUERQUE NM

A block-by-block, building-by-building survey of information from the Sanborn maps was conducted. Occupancy, block area, total floor area, height, number of floors, construction details, etc. were recorded for each building in the block being surveyed. These data were punched on IBM cards, verified, and put on magnetic tape. Computer summaries were then made of these data. From these summaries statistical analyses were made to detect whether any differences in construction occurred for given land uses due to 1 geographic region and 2 urban area size. From these results lists of typical urban areas were developed. From these basic data it was then possible to draw total mortality and total injury curves for an unwarned population daytime for each of the ten typical urban areas. These curves are presented for surface and the Hiroshima scaled height of burst 846 feet and for yields of 0.4, 1, 4, 10, 25, and 50 Mt. Capability is also provided for estimating casualties in a nighttime and a warned configuration. With this set of casualty curves classified by typical urban area and with land-use maps for the various cities of interest across the country, one is in a position to make both a practical and realistic casualty assessment on a national scale.
