Air Overpressure
Like blast vibrations Air overpressure waves radiate outward from a blast, diminishing with distance.Air overpressure from blasting is measured in either decibels or psi or, in the case of SI(metric) units, in Pascals.

Scaled depth of burial (SD or SDoB) is an empirical measure of blast energy confinement and can be described as the ratio of the stemming material to the amount of explosive within a space equivalent to 10 x hole diameters (Tobin, 2013)
Blast vibrations propagate outwardly as shockwaves from the blasthole with their intensity diminishing over distance. Shockwaves from multiple blastholes can combine to reinforce or cancel each other out. These waves can also reflect off variability in geological ground conditions.
