Lecture 16: March 8, 2016 Volcanoes  Explanations – Supernatural forces, assigning nature a personality. o Greco-Roman – Volcan (God of Fire) o Iceland – Surtr o New Zealand – love triangle o Hawaii – Pele o Kamchatka – Kurkh (Great Raven) o Pacific Northwest – Bridge of Gods  Rational Explanations o Greece and Roman  Empedocles – world divided into four elements Earth, Air, Fire, and Water.  Plato – an underground river of fire feeds all volcanoes.  Aristotle – earth full of underground passages where wind blows through. Volcanoes fed by fire caused by narrow friction of the wind when it flows through narrow passages.  Ovid – fire fed by fatty foods, when food used up eruptions stop. o Later European Views  Volcanoes are entrance to hell.  Agricola – vapor under pressure cause eruptions  Volcanoes caused by combustion of various materials/rocks.  Kepler – volcanoes are conduits for the tears and excrement ? Volcanoes have had positives and negatives for people, both in ancient times and today. ? Explanations for volcanic activity include:  Love triangles between giants and supernatural beings.  Winds traveled through underground caverns.  Tempered Gods. ? Volcanic eruptions can impact areas far from the volcano. ? Volcanic Activity has been linked to:  Mass migration of people.  Myths of Atlantis.  Crop failures.  The writing of Frankenstein. Lecture 17: March 10, 2016 Magma – molten rock below the surface of the earth. Lava – molten rock that has reached the surface of the earth and is either still molten or solidified. Tephra – fragments of material produced during a volcanic eruption – ash, lapilli, and bombs. Angle of Repose – the angle at which material will stay composed. Types of Volcanoes and Shapes:  Cinder Cone – material (tephra) erupts and piles around central vent – 25-35 degrees.  Stratovolcano (Composite) – made up alternating layers of tephra/lava – 30- 35 degrees.  Shield Volcano – all lava flows that build up volcano – 10-20 degrees.  Fissure – no central vent – dike. ? The steepest angle at which granular material comes to a stable rest is its angle of repose. ? The type of volcano that is most dependent on the angle of repose for its shape is a cinder cone. ? A shield volcano has the gentlest slope. Caldera – most typically stratovolcano – volcano erupts so much material that it collapses in on itself.  Aniakchak Caldera, Alaska  Crater Lake, Oregon  Katmai Caldera, Alaska  Aso Volcano, Japan ? Calderas can form at either a shield or stratovolcano. Lava Dome – lots of lava erupts and cools in place at top of volcano. Tuya (Subglacial Volcano) – lava hits meltwater and lava shatters. Where do Volcanoes occur?  Oceanic-Oceanic – typically Stratovolcanoes, can be shield.  Oceanic-Continental – mostly large stratovolcano, but can get all types.  Mid-Ocean Ridge – fissure eruptions.  Continental Rift – fissure eruptions, can possibly have cinder cones, shield, or stratovolcano.  Hot Spot – fissure or shield volcanoes.  Flood Basalts/Large Igneous Provinces – fissure eruptions. ? Transform Margins are not associated with volcanoes. Lecture 18: March 22, 2016 ? Transform margins are not associated with volcanism. ? Shield Volcanoes have the gentlest slopes of any volcano. ? Most of the worlds above sea volcanoes are stratovolcanoes and occur at subduction zones. Magma – mixture of liquid rock, gas bubbles, and crystals of various types of minerals.  Ways to get: o Wet partial melting (called flux melting) o Decompression Melting o Heat Transfer Melting – melts part of crust.  Types: o Basaltic – low silica – more dense – fluid - hot o Andesitic o Dacitic o Rhyolite (felsic) – high silica – less dense – viscous - cold Density – mass/volume – number and weight of molecules = amount of mass. Buoyancy – how something might rise because of different properties of its surroundings. ? The addition of water can lower the melting point of rock. ? Divergent Margins is more likely to have magma generated by decompression melting. ? Felsic magmas have more silica than mafic magmas.
