Volcano facts What causes volcanoes? Inside the earth's core there is a red-hot liquid rock, called magma. Volcanoes happen when magma rises to the surface of the earth, which causes bubbles of gas to appear in it. This gas can cause pressure to build up in the mountain, and it eventually explodes. When the magma bursts out of the earth, it is called lava. E-mail this page to a friend next Back to top^^ Homepage ... Club

Volcanism is part of the process by which a planet cools off. Hot magma, rising from lower reaches of the Earth, eventually, but not always, erupts onto the surface in the form of lava. During the eruption of a volcano, flowing lava and ash , forming a large cone. This cone is what we know as a volcano. Among the different kinds of volcanoes are: shield volcanoes cinder cones composite volcanoes The most prevelant of kinds of volcanoes on the Earth's surface are the kind which form the " Pacific Rim of Fire ". Those are volcanoes which form as a result of subduction of the nearby lithosphere.

The youngest mountain Mount St. Hellacious Mount St. Helens, one of the Cascade volcanoes along the Pacific coast, is back to rumbling, gassing, belching and generally making people nervous. She's quiet, then she's loud. A lava dome is building inside the crater, sure evidence that molten rock is rising. October 2004: Mount St. Helens in Southwest Washington State is erupting again. The mountain is seen from the Johnston Ridge Observatory. During the 1980 eruption, a hurricane of rock swept over this ridge, killing volcanologist Dave Johnston. Photo USGS The mountain could go back to sleep. Or it could go ballistic without further notice: "As long as this eruption is in progress, episodic changes in the level of activity can occur over days, weeks, or even months. Increase in the intensity of eruption could occur suddenly or with very little warning and may include explosive events that produce hazardous conditions within several miles of the volcano." That's as far as the experts can tell us. We can't add much, except to remember her horrific sideways blast of 1980, which burned, crushed, buried or asphyxiated 57 people, most of them outside the official danger zone.

Quick Facts about Mountains There are more than active volcanoes on the Earth . W e currently know of 80 or more which are under the oceans. The Earth's crust is made up of huge slabs called plates, which fit together like a jigsaw puzzle. These plates sometimes move. The friction causes earthquakes and volcanic eruptions near the edges of the plates. The theory that explains this process is called plate tectonics Did you know? Volcanoes are like giant safety valves that release the pressure that builds up inside the Earth. What is a Volcano? A volcano is a geological landform (usually a mountain) where magma (rock of the earth's interior made molten or liquid by high pressure and temperature) erupts through the surface of the planet. In simple terms a volcano is a mountain that opens downward to a pool of molten rock below the surface of the earth. It is a hole in the Earth from which molten rock (magma) and gas erupt.

No other company in the world has invested so heavily in the area around the mountain gorilla parks in these two countries. Over the last decade, Volcanoes Safaris has taken over 5,000 clients on gorilla safaris and we currently employ over 100 people globally. This exceptional track record makes Volcanoes Safaris the No. 1 Gorilla Safari Company. Volcanoes Safaris has created an unrivalled and integrated set of ecotourism services to share with clients the great apes of Africa. Volcanoes was at the forefront of opening tourism around the Ugandan gorilla parks a decade ago and in 2000 became the first international up-market safari company to take clients to see gorillas in post-conflict Rwanda, a vital step in relaunching its international tourism. Volcanoes is now using this pioneering experience to advise conservation organizations, governments and donors on how to launch great ape ecotourism in the forgotten forests of the Congo Basin.

Our scientific analysis provides the vital information needed for thorough planning and will help minimise the impact of future volcanic eruption. We maintain permanent surveillance at active and potentially active volcanoes - the best way to detect the early signs of increasing seismic and volcanic activity.

The catastrophic eruption of Mount St. Helens on May 18, 1980, made clear the awesome destructive power of a volcano. Yet, over a time span longer than human memory and record, volcanoes have played a key role in forming and modifying the planet upon which we live. More than 80 percent of the Earth's surfaceabove and below sea levelis of volcanic origin. Gaseous emissions from volcanic vents over hundreds of millions of years formed the Earth's earliest oceans and atmosphere, which supplied the ingredients vital to evolve and sustain life. Over geologic eons, countless volcanic eruptions have produced mountains, plateaus, and plains, which subsequent erosion and weathering have sculpted into majestic landscapes and formed fertile soils. Ironically, these volcanic soils and inviting terranes have attracted, and continue to attract, people to live on the flanks of volcanoes. Thus, as population density increases in regions of active or potentially active volcanoes, mankind must become increasingly aware of the hazards and learn not to "crowd" the volcanoes. People living in the shadow of volcanoes must live in harmony with them and expect, and should plan for, periodic violent unleashings of their pent-up energy.
