Volcanic eruptions occur when pressure builds up beneath the Earth’s surface, usually due to the movement of tectonic plates or the presence of a magma chamber. As molten rock, or magma, rises towards the surface, it encounters resistance from the surrounding rock layers, causing pressure to build. When this pressure becomes too great, it can lead to a sudden release of energy, resulting in an eruption.

There are several types of volcanic eruptions, ranging from relatively mild effusive eruptions, where lava flows steadily from the vent, to explosive eruptions, characterized by the violent ejection of ash, gas, and volcanic rock fragments. The type of eruption depends on factors such as the composition of the magma, the presence of gases, and the shape of the volcano’s vent.

Once an eruption begins, the magma may travel upwards through cracks and fissures in the Earth’s crust, eventually reaching the surface through a volcanic vent. The release of pressure causes gases dissolved in the magma to expand rapidly, propelling magma, ash, and other volcanic material into the air. This can result in the formation of lava flows, ash clouds, pyroclastic flows, and other volcanic phenomena, which can have significant impacts on the surrounding environment, including damage to infrastructure, loss of life, and changes to the landscape.
