Explosion

Explosion is the rapid release of energy accompanied by a shock wave, increased temperature, and gas emission. Explosions can result from man-made, natural, or military factors.

Main types of explosions:

1. Chemical — caused by combustion or detonation of explosives (e.g., industrial or military explosions).
2. Physical — caused by rupture under pressure (e.g., gas cylinder explosions).
3. Nuclear — release of energy from a nuclear reaction.

Context in Ukraine:

Explosions in Ukraine are often linked to military activities, especially after Russia's full-scale invasion in 2022. Additionally, industrial explosions at critical infrastructure such as gas pipelines or ammunition depots remain a concern.

Explosions pose a significant threat to civilians, particularly due to landmines and unexploded ordnance that can detonate long after hostilities have ended.
