Causes of Volcanic Eruption
Volcanic eruptions have these three primary causes:
1. The Magmatic Buoyancy
Magma buoyancy creates a background overpressure that can gradually rise. This overpressure either prepares the magma chamber for a subsequent trigger or may eventually cause a super-eruption on its own.
2. Dissolved Pressure in the Magma
Nearly all magmas at Earth’s depths have gas dissolved in the liquid; however, as magma rises toward the surface, pressure decreases and the gas separates into a vapor phase. This is comparable to highly pressurized bottles of fizzy drinks.
3. Increased Pressure in the Magma Chamber
Pressure rises when magma fills the chamber. Magma can burst through the crust and erupt as a volcano if the pressure builds up sufficiently. Volcanic eruptions typically take place above subduction zones.
Volcano Eruption
A Volcanic Eruption is the release of hot gases, molten rock, and hot rock fragments through a volcano. A volcano is a vent in the crust of a planet or satellite. Volcanic eruptions can result in catastrophic property and human loss. Volcanic eruptions might even be almost harmless, like most volcanoes in Hawaii. They can also be extremely devastating, as when Pompeii was destroyed by Vesuvius’ explosion in 79 CE. In this article, we will look into the definition, causes, types, and effects of volcanic eruptions. We will also explore the recent volcano eruptions.
