An eruption begins when there is a buildup of pressure within a volcano due to the accumulation of magma beneath the Earth's surface. This pressure can be caused by the movement of tectonic plates, the melting of rocks, or the release of gases. Once the pressure exceeds the strength of the surrounding rock, it results in an explosive release of magma, gases, and ash, leading to a volcanic eruption. The initial rupture often occurs at a weak point in the volcano, allowing the magma to escape.
