health‚ property‚ or environment. It is easy to locate volcanoes‚ but it is very difficult to predict exactly when activity will take place‚ particularly a major eruption‚ this makes it difficult to prepare or plan for one. There is a very big difference that helps prepare for a volcanic hazard and that is whether you are in a MEDC or a LEDC. In a MEDC monitoring volcanic zones and potential hazards is an option many LEDC’s don’t have. In Italy at Mt Etna they have Geo-monitoring programs which focus

This also shows relief. * On the west‚ there is pacific plate called “The Ring of Fire” –more than 50% of world’s volcanoes‚ earthquakes occur in this area. 1.1 Geological Structures: Stable Landforms * Ancient Platforms or (Cratons): is about 2 billion years ago when they were created Russia has 2 ancient platforms or Cratons: * Eastern European Cratons

Plural volcanoes‚ or volcanos‚ any vent in the crust of the Earth or other planet or satellite‚ from which issue molten rock‚ pyroclastic debris‚ and steam. Volcanism (vulcanism) is the name given to the processes and phenomena associated with the surficial discharge of such material from volcanoes‚ geysers‚ and fumaroles. Volcanoes figure prominently in the mythology of many peoples who have learned to live with eruptions‚ but science was late in recognizing the important roleof volcanism in

Me and My Volcano Volcanoes exist all around the world. There are three types of volcanoes‚ they are shield volcano‚ cinder cone volcano and a composite volcano. A volcano is a place where ash‚ gases‚ and molten material rock from deep underground erupt to the surface. Lava comes out of a vent ‚ then it turns into a lava flow. When external waters‚ such as groundwater ‚ mixes with magma and then it turns into steam. The violence of an eruption depends on the amount of gas that was dissolved

the “scientific study of the origin‚ history and structure of the earth”. It involves understanding earth’s processes‚ materials and its effects on all forms of life. From earth elements such as rocks and mountains to natural phenomenon such as volcanoes and earthquakes‚ the field of geology encompasses a wide range of concepts fundamental to many professions and to civilization in general. Scientific disciplines such as civil engineering and environmental sciences‚ for instance‚ rely on a deeper

Melanie Brooke Yeakley 1. What is the myth from which volcanoes get their name? •It comes from the little island of Vulcano in the Mediterranean Sea off Sicily. Centuries ago‚ the people living in this area believed that Vulcano was the chimney of the forge of Vulcan--the blacksmith of the Roman gods. They thought that the hot lava fragments and clouds of dust erupting from Vulcano came from Vulcan’s forge as he beat out thunderbolts for Jupiter‚ king of the gods‚ and weapons for Mars‚ the god

differences between the material erupted by these volcanoes. Volcanic eruptions are caused by a red-hot liquid rock‚ called magma inside the earth’s core. Volcanoes erupt 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. The type of magma in the earth can create different volcanoes. If the magma is quite thin‚ the gas can

Philippines also suffered $550 million USD in damage. Volcanic eruptions are the Earth’s most powerful and destructive forces. An eruption begins when pressure on a magma chamber forces magma up through the volcano’s vents. The explosion of Mount Tambora‚ which is still active‚ is one of the tallest peaks in the Indonesian
