What Happens during a Volcanic Eruption?

Answer

During a volcanic eruption, the pressure in the magma chamber builds up and pushes the magma upwards. This magma is eventually forced out through vents resulting in dangerous, bright orange jets of lava being shot hundreds of metres into the air. Afterwards, excess magma flows from the vents and a much slower speed.

Ask.com Answer for: what happens during a volcanic eruption
When a volcano erupts, hot magma (molten rock), gases and volcanic ash are emitted. The explosiveness of the eruption depends on the consistency of the magma and the amount of pressure built up prior to eruption.
There are different types of volcanic eruption, but what is common to all of them is the seismic activity. When a volcano erupts, the first sign will be an earthquake, then it will start sending out ash and gas until finally, lava is expelled from the crater. Some eruptions are so violent that ash can reach several thousand feet into the atmosphere.
