The risk of living near a volcano is obviously very high‚ but these risks are calculated. People don’t live on the side of a volcano because of the thrill‚ there is much more to why people do it. The dangers of living so close to an active volcano can be catastrophic‚ lava flows‚ lahars‚ and pyroclastic flows can all be devastating‚ so why then do people do it‚ people like those who live on the sides of Merapi‚ Indonesia‚ and those of Pinatubo in the Philippines‚ there is no denying that it happens

Im guessing and hoping everyone has probably heard this saying hundreds of times before. Either by friends‚ parents‚ or other relatives. Now as cliche as that may sound‚ and probably the hundred more times more you are going to hear this‚ the fact of the matter is it is true. Now im sure‚ everyone in this has thought about the end of the world and whether or not the end is near? From the issue of global warming‚ it being mentioned in religious texts‚ to the conspiracy theory of huge asteroids

Undara Lava tubes consist of a lava field remaining from a massive volcanic eruption of Mt Undara which occurred 190‚000 years ago. During the Cenozoic‚ there was wide spread igneous activity in Eastern Australia. Volcanism commenced in the late Cretaceous (approximately 70 Ma) and continued through the Cenozoic. The cenozoic is the current geological era. It began 66 million years ago and continues today. About 23.3 km³ of lava flowed from the Mt Undara volcano at an estimated rate of 1000 m³ a

With reference to examples‚ discuss the ways in which the nature of volcanic hazards can vary Events that cause death‚ injury and damage to property and infrastructure are known as natural hazards. Volcanic eruptions can swiftly become natural hazards which can quickly lead to major loss of life and widespread damage. Primary hazards that are associated with volcanoes include; pyroclastic flows‚ Tephra‚ Lava flows and volcanic gases. Pyroclastic flows are waves of very hot gases and tephra with

Impact Approximately 57 deaths‚ about $1.1 billion in property damage; caused a partial collapse of the volcano’s flank‚ deposited ash in eleven states and five Canadian provinces. With no immediate precursors‚ a magnitude 5.1 earthquake occurred and was accompanied by a rapid series of events. Mount St. Helens produces small to large explosive eruptions‚ which send varying quantities of ash and tephra into the atmosphere Tephra (rock fragments and particles ejected by a volcanic eruption

Me and My Volcano Volcanoes exist all around the world. They can be very dangerous or unharmful. Some may seem unharmful because of their appearance‚ but they really are harmful to humans and wildlife. Volcanoes occur when two tectonic plates collide or‚ when there is a hot spot in the crust and constructive forces build a volcano. There are two types of volcanic flows pyroclastic and mud flows. Pyroclastic volcanoes occur when the amount of magma in the chamber collects and the pressure

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

EARTH ENVIRONMENTS I: GEOMORPHOLOGY AND SOILS Question: compare and contrast the styles of eruptions and the volcanic features both landward and seaward of the Andesite Line. “The term andesite line predates the geologic understanding of plate tectonics.” In that it was the term first used to describe the unique structure of the gushing destructive volcano boundary. This term used for the first in 1912 by a man known to be Patrick Marshall of New Zealand. The andesite line is located in the Pacific

Mount Yasur is an active volcano on Tana Island‚ Vanuatu with a height of 361 m above sea level‚ located on the coast near Sulphur Bay‚ that lies to the southeast of the taller mountain Tukosumera‚ which was active in the Plesistocene. It has a largely unvegetated pyroclastic cone with nearly a circular summit crater of 400 m in diameter. It is a stratovolcano caused by the eastward-moving Indo-Australian Plate being sub-ducted under the westward-moving Pacific plate. It has been erupting continuously

A metamorphic Rock can be formed by simply being under the earth’s surface‚ being exposed to extremely high temperatures and a huge amount of pressure from the layers of rock above. These rocks can be formed by tectonic processes‚ some which include‚ continental collisions (this is a process that causes friction‚ distortion and horizontal pressure). These rocks can also be formed when rock becomes heated rapidly by the intrusion of a hot molten rock‚ (called magma) and it comes from the earth’s interior
