Peak Particle Velocity Doesn't Cut It

A number of famous studies have shown that house damage relates better to peak particle velocity than to acceleration or displacement. The relationship is true but doesn't go far enough. Why, for example, can construction shots go well above 1.0 or 2.0 inches per second without reportable damage? Recent studies have shown that vie must look at frequency and duration of an event in addition to amplitude. The complexity of measuring frequency, duration, and amplitude makes the average blaster in the field shudder. An even more excruciating problem is the need to obtain such data inside the building or residence in order to accurately predict the damage potential or human response to nearby blasting. The author reviews current research programs and suggests new areas of research necessary to help maintain a balance between complicated research requirements and simple field measurements.
