Volcanoes that have erupted within the last decade include Bulusan in the Phillippines and Copahue, which is near the border of Chile and Argentina. Some volcanoes, such as Kilauea in Hawaii and Mount Etna in Italy, have been erupting more or less continuously for decad...
When a volcano erupts, magma from beneath the Earth is forced out of the volcano's mouth in the form of molten lava. Large amounts of gases and ash can also be released with the lava, depending on the type of eruption.
Volcanoes erupt due to pressure that the weight of the rocks puts on the magma and forces it to the surface out any available vent or exit provided to it. The magma is in a reservoir like area under the surface and the pressure from the rocks causes the less dense magma...
A volcano erupts through the build-up and release of pressure, whether that pressure is of its underlying magma, water or both. This release can be explosive, as it was in the famous eruption of Mt. Vesuvius that destroyed Pompeii, or it can be slow and effusive, as it ...
VolcanoDiscovery.com is a website created and maintained by an international group of scientists and volcanologists that provides up-to-date information on current volcanic eruptions around the world. The Smithsonian's Global Volcanism Program also publishes regular eru...
A volcano erupts when the pressure of a subterranean pool of magma becomes great enough to crack the earth's crust. Whether the eruption results in a violent explosion or a slow seepage depends on several different factors, according to How Stuff Works.
The first volcano erupted approximately 4.5 billion years ago. This is when the earth first came into existence, and long before the first humans walked the earth, according to Scholastic, Inc.
