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.
A volcanic eruption starts with the build up of pressure in the magma chamber. A bulge in the crater may indicate a impending eruption. Earthquakes may also precede an eruption.
Volcanic eruption can be classified mainly based on the name of the volcano. They are Surtseyan eruption, Plinian eruption, Vulcanian eruption, Strombolian eruption and Hawaiian eruption.
The 79 AD eruption of Mount Vesuvius, which destroyed Pompeii, was a Plinian eruption. In fact, it was the description of this eruption by Pliny the Younger that lead to the term Plinian.
The answer is : Magma with low viscosity. It makes for a weak volcanic eruption. If the viscosity is low (thin), non-explosive eruptions usually begin with fire fountains due to release of dissolved gases. When magma reaches the surface of the earth, it is called lava.
An major eruption
Phreatic Eruption (an explosive volcanic eruption)
A volcanic eruption starts with the build up of pressure in the magma chamber. A bulge in the crater may indicate a impending eruption. Earthquakes may also precede an eruption.
Vesuvius began erupting on August 24, 79 CE
The explosive eruption on Mt. Etna took place on May 23, 1992. In all, Etna was actually erupting and venting gas for almost two years before it calmed again.
Permanent dentition begins with the eruption of the first permanent molars.
Volcanic eruption can be classified mainly based on the name of the volcano. They are Surtseyan eruption, Plinian eruption, Vulcanian eruption, Strombolian eruption and Hawaiian eruption.

no it was a loud eruption
The toba eruption was ultra plinian.
What kind of eruption? If it is a huger eruption then you should eat a sandwich.
