where Vo is the maximum ground particle velocity at the seismograph, Do is the distance of the seismograph from the blasting, and D is the distance from the blasting to the position in question and in the same general direction. The distance Do may not be greater than D, and D cannot be more than five times Do. This determined velocity at the site of any dwelling house, public building, school, church, or commercial or institutional building normally occupied shall not exceed the two inches per second limit.
