The impact of an underground explosion can range from the creation of a spherical cavity to the generation of shock waves that can trigger earthquakes.
Types of Underground Explosions:
Mine Explosions:
Mine explosions can occur in underground mines and can be caused by the detonation of explosives or the sudden release of methane gas, which is common in coal mines.
Cavity Collapses:
Underground cavities can collapse due to the instability of the surrounding rocks, generating an explosion or a strong impact. Volcanic Explosions:
Although not strictly underground explosions, volcanic eruptions can have a significant subterranean component, with explosions occurring within the volcano before materials are ejected to the surface.
Effects of Underground Explosions:
Shock Waves:
The explosion generates shock waves that propagate through the ground, potentially causing damage to nearby structures or even triggering earthquakes.
Damage to Structures:
Structures near an underground explosion may be damaged due to vibration and the shock wave.
Gas Release:
In the case of mine explosions, gases such as methane may be released, which can be dangerous.
