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 Ocean basin where it stands as the most significant geological region as once again its unique characteristic

5. What is the basic structure of a volcano? Vents‚ lava‚ magma chamber‚ and ash 6. What is the difference between an explosive and a non-explosive eruption? Nonexplosive Eruptions * Most common type * Laval flows from them calmly. (can be huge amount) Explosive Eruptions * Rarer than nonexplosive eruptions * Are very destructive as pyroclastic materials are flung into the air. 7. What materials erupt from a volcano? Pyroclastic materials and lava. Types

that produced these explosive eruptions (VEI 3>=3; 2001-2012) is the strato-volcano. The nature of these volcanoes in general. Is that they have deadly pryoclastic flows of hot fragments and toxic gases the explosive nature comes from silica in the magma. The few other types of volcanoes are shield‚ cinder and complex (compound) volcanoes. One type of volcano is‚ Etna this volcano is also entitled a “strato volcano” it produces violent activity including lots of ash‚ lava and gas which causes

historic eruptions have a lot in common. For example‚ both were preceded by tremors and small earthquakes in the days leading up to both of the explosions. Another example is that both are the same type of volcano called a stratovolcano that spew a lot more ash and pumice than other types of volcanos. The final example is that both spewed tons of ash and pumice and in both situations that was why they were considered deadly. Those are examples of the similarities these

To what extent are volcanoes more harmful to our society than earthquakes? Many people may argue that volcanoes are much more dangerous than earthquakes due to the devastating impact it has on people lives and the area it takes place in; however‚ others may solidify that earthquakes are infinitely more catastrophic than volcanoes considering the amount of destruction that it causes. There are two types of plates‚ oceanic and continental. Various types of movement occur along the different types

Assess the extent to which primary rather than secondary impacts are the more serious effects arising from volcanic eruptions. (30 marks) A volcano is an earth hazard that occurs on faults between tectonic plates on a destructive boundary and an eruption is a natural disaster. A primary impact happens immediately after the disaster and before any response like death or collapsing or destruction of buildings. A secondary impact occurs later after the disaster‚ such less farm produce or a reduction

Geoff Hibbs May 4‚ 2012 Primary Succession & Species Diversity of Flora on Mount St. Helens‚ 32 Years PostEruption On May 18 1980‚ Mount St. Helens‚ a stratovolcano in western Washington‚ erupted. The eruption scoured the slopes of the volcano removing vegetation and soil from the vicinity of the mountain. 32 years after the eruption‚ vegetation has returned to the mountain. The author’s main interest in this field is the methods by which vascular plants re-establish themselves after cataclysmic
