A volcanic eruption is the expulsion of gases, rock fragments, and/or molten lava from within the Earth through a vent onto the Earth's surface or into the atmosphere.
.A volcanic eruption is a natural phenomenon that occurs when magma, or molten rock material, is released from a volcano. This release can be calm and effusive, or it can be explosive.
Scientific American
Effusive eruptions produce lava flows, while explosive eruptions produce ash and pyroclastic density currents.
Volcanic eruptions can be caused by a burst in the Earth's crust due to the movement of tectonic plates. If the lava is extremely thick, it can build up in the volcano and explode, known as lava domes.
Volcanoes provide a number of environmental benefits, including fertile soils, hydrothermal energy, and precious minerals.
If you're outside during a volcanic eruption, you should seek shelter in a car or a building. If you're caught in volcanic ashfalls, you should wear a dust mask or use a handkerchief or cloth over your nose and mouth. You should stay indoors as volcanic ash is a health hazard, especially if you have respiratory difficulties such as asthma or bronchitis.
