Low order explosions are characterized by what feature?

Low order explosions are typically associated with a pushing or cratering effect rather than a high-order detonation, which would create a wave of destruction. This characteristic is evidenced by the way low order explosives, such as black powder, function; they produce a slower rate of pressure increase compared to high order explosives. The pushing effect creates large fragments of material being displaced, which can be significant in terms of the resulting damage.

The large broken pieces observed after such explosions are a result of the explosion’s energy manifesting as a push, which can scatter debris over a wide area, albeit with less destruction than a more violent explosion would entail. This pushing effect is crucial in forensic investigations as it aids in understanding the nature and mechanics of the explosion, helping to establish the type of explosive used and the implications for safety and structural integrity.
