The U.S Bureau of Mines has studied the vibration and airblast impacts of munitions disposal blasts at the U.S. Army Ammunition Depot, McAlester, Oklahoma. The impacted community believed that the army was causing structural damage, had an active political action program, and was contemplating legal action. Using techniques developed for analyzing mining blasts, the Bureau installed multichannel recording systems at 11 houses on and around the base. Ground vibration, airblast, and structural response was monitored over a period of 18 months. Distances to monitored structures ranged from 3.9 to 15.2 Km with the closest outside community being Savanna at 6.2 Km. This paper is a summary of the study, which is described in detail in a contract final report to the U.S. Army; it was found that adverse effects on structures from ground vibrations and airblasts were unlikely and nil, respectively, although airblast amplitudes could possibly be high enough to occasionally break windows at the closest structures.
