This paper presents a fracture mechanics model of smooth blasting and pre-split blasting, analyzes the function of stress waves and quasi-static pressureofexplosion in blasting process.
The meltwater from the glacier on top of the volcano ran down into the crater, chilling the magma and then the pressure from underneath caused an explosion.
火山顶部的冰川融水流进了火山口，冷却了岩浆，随后来自底部的压力造成了爆炸。

The pressure increase out of control was at the bottom of the explosion.
