  22. 22. Volcanoes CHAPTER 2 22
  23. 23. Definitions      Viscosity - the property of a fluid that resists the force tending to cause the fluid to flow Magma - molten material beneath or within the earth's crust, from which igneous rock is formed Lava - the molten, fluid rock that issues from a volcano or volcanic vent Ash - the powdery residue of matter that remains after burning Caldera - A large crater formed by volcanic explosion or by collapse of a volcanic cone. 23
  24. 24. What is a volcano?  A volcano is an opening in the Earth’s crust, which allows hot magma, ash and gases to escape 24
  25. 25. Structure of a Volcano 25
  26. 26. What Greeks Believed  Volcano is from the Latin word vulcan  Thought it was an entrance to the fiery underworld.  Thought the god of Fire, Hephaestus, lived beneath Mt. Etna 26
  27. 27. Ring of Fire!!  90% of volcanoes are in the Ring of Fire which is band of volcanoes circling the Pacific Ocean 27
  28. 28. Largest Volcano in the World • • • • • Mauna Loa, on Hawaii’s Big Island Shield Volcano Made by several lava flows Top to bottom 56,000 ft Last eruption in 1984 28
  29. 29. Classify  Active - has erupted since the last ice age  Dormant – hasn’t erupted in the last 10,000 years, but is expected to erupt again  Extinct – no one ever expects it to erupt again 29
  30. 30. Types of Volcanoes  Shield volcano  Stratovolcano  Supervolcano  Submarine volcano  Subglacial volcano  Mud volcano 30
  31. 31. Shield Volcano     Broad, shield like profile Formed by the eruption of low-viscosity lava that can flow a great distance from a vent Since low-viscosity magma is typically low in silica, shield volcanoes are more common in oceanic than continental settings. Found in Hawaii and 31
  32. 32. Stratovolcano     Tall conical mountains composed of lava flows in alternate layers Also known as composite volcanoes, created from several structures during different kinds of eruptions Made of cinders, ash and lava. Cinders and ash pile on top of each other, lava flows on top of the ash, where it cools and hardens, and then the process begins again. Mt. Fuji, Mt. Vesuvius, and Mt. Mayon are examples 32
  33. 33. Supervolcano  Large volcano that usually has a large caldera and can potentially produce devastation on an enormous, sometimes continental, scale  Such eruptions would be able to cause severe cooling of global temperatures for many years afterwards because of the huge volumes of sulfur and ash erupted  They are the most dangerous type  Examples include Yellowstone Caldera in Yellowstone National Park and Valles Caldera in New Mexico  Hard to identify centuries later, 33
  34. 34. Submarine Volcano  Common features on the ocean floor.  Some are active and, in shallow water, blast steam and rocky debris high above the surface of the sea.  Many others lie at such great depths that the tremendous weight of the water above them prevents the explosive release of steam and gases, although they can be detected by hydrophones and discoloration of water because of volcanic gases. Pumice rafts may also appear. Even large submarine eruptions may not disturb the ocean surface. • Because of the rapid cooling effect of water as compared to air, and increased buoyancy, submarine volcanoes often form rather steep pillars over their volcanic vents as compared to above-surface volcanoes. They may become so large that they break the ocean surface as new islands. 34
  35. 35. Subglacial Volcano      Develop underneath icecaps. Made up of flat lava which flows at the top of extensive pillow lavas When the icecap melts, the lavas on the top collapse leaving a flat-topped mountain. Also called table mountains Examples are in 35
  36. 36. Mud Volcano  Formations created by geo-excreted liquids and gases, although there are several different processes which may cause such activity.  The largest structures are 10 kilometers in diameter and reach 700 meters high. 36
  37. 37. Mt. St. Helens  Located in Washington  Stratovolcano  Most famous for eruption on May 18, 1980  Most active volcano in United States 37
  38. 38. May 18, 1980  Most catastrophic eruption  57 people killed, 250 homes, 47 bridges, 15 miles of railway, and 185 miles of highway were destroyed  Caused a mass debris avalanche bringing the elevation from 9,667ft to 8,365ft  Made a horseshoe shaped crater 38
  39. 39. Volcano Benefits  Provide valuable mineral deposits  Fertile soils  Geothermal energy  Lava can build new land, like in Hawaii 39
  40. 40. Safety tips •Stay away from active volcanoes. • If you live near an active volcano, keep goggles and a mask in an emergencykit, along with a flashlight and a working, battery-operated radio. • Know your evacuation route. Keep gas in your car. If a Volcano Erupts in your Area • Know your evacuation route. Keep gas in your car. • Evacuate only as recommended by authorities to stay clear of lava, mud flows, and flying rocks and debris. •Avoid river areas and low-lying regions. •Before you leave the house, change into long-sleeved shirts and long pants and use goggles or eyeglasses, not contacts. Wear an emergency mask or hold a damp cloth over your face. •If you are not evacuating, close windows and doors and block chimneys and other vents, to prevent ash from coming into the house. •Be aware that ash may put excess weight on your roof and need to be swept away. Wear protection during cleanups. •Ash can damage engines and metal parts, so avoid driving. If you must drive, stay 40 below 35 miles (56 kilometers) an hour.
  41. 41. Conclusion Now, to sum up my presentation the main points of my presentation is about Pacific ring of fire. Pacific ring of fire is a group of volcanoes surrounding many counties. Philippines is a part of pacific ring of fire Volcano is very destructive. Volcano can make an Earthquake because of volcanic activities and some after volcanic eruption. In conclusion, my recommendations are : your mind should be active in calamities you have to be ready if theres any calamities written in this conlusion. 41
