Informative Speech On Super Volcanoes
Super volcanoes
We are now in year 2016, and I believe that almost all people in the United State remember the disaster film called “2012”. The catastrophe included great eruptions of super volcanoes in America, such as Yellowstone. There are a lot of scientists doing researches of super volcanoes, and trying to predict when will the super volcanoes erupt again. Today I would like to introduce some knowledge of super volcanoes, and the reason why people do not need to worry about hazards of eruptions of super volcanoes.
“The term "super volcano" implies a volcanic center that has had an eruption of magnitude 8 on the Volcano Explosivity Index (VEI), meaning the measured deposits for that eruption is greater than 1,000 cubic kilometers (240 cubic miles)”. (Questions About Super volcanos, 2015). According to the definition of super volcano, we know that super volcano is actually a kind of volcano, which erupt more than one thousand cubic kilometers of deposits. Within last 2 million years, there are some volcanoes that produced extremely voluminous pyroclastic …show more content…
There is a theoretic solution that people could drill into the volcano, and help it to release some energy. However, this solution has been denied because of unfeasibility. Then government set a lot of observation stations at active volcanoes in order to observe and analysis volcanoes activities. Hence I believe that scientists could notice people when the super volcanoes would erupt, and they could figure out how to prevent eruptions.
To draw a conclusion, we do not need to worry about eruptions of super volcanoes for these following reasons: the probability of eruption is extremely low; scientists do not detect evidences of currently eruptions. On the other hand, I hope scientists could understand why super volcanoes erupt, what causes eruptions, and how to prevent

    Pompeii Research Paper

    Volcanoes are formed on land near coastal areas when a continental plate and an oceanic plate converge. The oceanic plate submerges, due to its higher density, and is pushed deeper and deeper beneath the surface. The high temperature and pressures below melt the rock which creates hot, buoyant magma. Ultimately this magma rises towards the surface and accumulates in a reservoir, known as the magma chamber. The eruption occurs when the pressure within in the chamber surpasses the pressure of the upper rock, magma forces its way through the cracks in Earth’s crust. Magma that is low in gas and silicon dioxide produces thin quickly spreading lava which has a low viscosity, while a magma that is heavily composed of gas and silicon dioxide will yield a thick, viscose magma. The thicker magma builds up and because of this pressure, will cause a large…

    Why Pt. Thunder Is A Volcano

    Overview To all the residents in the village of Boomsdale, recently Dr. Bigbrain with the United States Geological Survey (USGS) has detected small earthquakes coming from Mt. Thunder. For those of you that do not yet know, Mt. Thunder is an active stratovolcano and these earthquakes could be related to an impending volcanic eruption. There are three types of volcanos which include: shield volcanos, scoria cone volcanos, and stratovolcanoes. Unfortunately, stratovolcanoes are the most dangerous, explosive, and deadly volcanoes. The reason for stratovolcano’s explosive tendency is because of the type of magma contained in the volcano’s magma chamber located underground beneath Mt. Thunder.…

    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 in tourism. The severity of these impacts will differ considerably in a MEDC and LEDC where volcanic eruptions have taken place. These may be seen in the Mount St. Helen volcano eruption as well as in the Iceland volcanic eruption. They may also show that the impacts vary from volcano to volcano, place to place.…

    Jfk Research Paper

    Scientist Ben Kennedy begun a very lengthy quest to solve the mystery of the shrinking pumice. This quest would eventually change the way scientists think about volcanoes-forever. One of the things (out of many) that he and his colleagues found out while on the road was that not only the rock was shrinking, the pores that make up the rock were shrinking as well. They think that this was due to the heating of the rock, and the molten rock's surface tension. What the scientist found was how some volcanoes function on the inside. In past years, volcanologists believed that flowing lava sinks back down and settles after an eruption, pressing on the magma below and crushing all of the bubbles, which makes pressure build up under the compacted lava. This leaves the lava sitting there...Until it explodes. Pow! This hints at why some volcanoes will go through cycles of flowing and explosive eruptions.…

    To What Extent Can Volcanic Hazards Be Managed Effectively

    The most recent eruptive period was in the 1980’s. Due to USGS (United States Geological Survey) geologists observations of a large bulge measuring 140m on the north face of the volcano. Using modern laser and radar technology they were able to track the movements of this bulge in order to predict when the volcano was in danger of erupting from a an observation tower 6 miles away. With this data collected the authorities were convinced to shut off the volcano to the local populations who make use of the volcano’s fertile soil for a large logging business and many recreational users who walk dogs or come to enjoy the views. As will be shown later, the shutting of the volcano saved many local thousands of tourists, workers and locals lives alone.…

    Hawaiian Volcanoes Essay Example

    Viewing an erupting volcano is a memorable experience; one that has inspired fear, superstition, worship, curiosity, and fascination throughout the history of mankind. The active Hawaiian volcanoes have received special attention worldwide because of their frequent spectacular eruptions, which can be viewed and studied with a relative ease and safety. The island of Hawaii is composed of five volcanoes, three of which have been active within the past two hundred years. Kilauea's latest eruption still continues as of today. Mauna Loa's latest activity was in 1984 and Hualalai's in 1800-1801, but is likely to erupt again within the next one hundred years. East Maui, or Haleakala, one of the oldest volcanoes, has a long eruptive history and recent activity indicates that the volcano will erupt in the near future. Last but not least, the Loihi Seamount, sometimes known as the "youngest volcano" is an undersea mountain this is still active. Scientists now believe that the hot spots lie in the ocean, deep beneath the volcanoes. These hot spots spew out of molten rock that rises to the water's surface and hardens. After doing this for a long time, the hardened lava forms an island, like the Hawaiian islands (Volcanoes Online).<br><br>The Kilauea volcano is one of the most active volcanoes on earth. It's current eruption started in January 1983, and there is no signs that the current eruption is slowing or will come to an end anytime soon. The U.S. Geological Observatory monitors the daily activities of the volcano, for example-movement of lava flows, earthquakes, surface deformation, and gas production. Kilauea has been monitored ever since, making it one of the better-studied volcanoes. Still there is much we don't understand about the inner workings of this volcano. Unlike most other volcanoes though, Kilauea is approachable. It has been called the "drive up" volcano because of the ease of access to many of its volcanic activity. On February 24, 2000, an article came…

    yellowstone

    A supervolcano is any volcano capable of producing a volcanic eruption with an ejecta volume greater than 1000 km cubed. This is about 1000 times bigger than a normal volcanic eruption. super volcanos don’t tend to be visible from the ground as they are so big. This is because the caldera, a large volcanic crater, are so big, in the case of Yellowstone it is over 40 miles across, so people do not recognize it as a volcano. Super volcanos occur when magma in the mantle rises into the crust from a hotspot but is unable to break through the crust, due to this pressure builds in a large and growing magma pool until the crust is unable to contain the pressure, this is what will and is happening at the Yellowstone caldera. These can also be formed at convergent plate boundaries, this is what is happening at Toba.…

    The Mauna Loa Volcano

    This is partly due to the fact that the volcano was covered in cloud at high elevation and helicopters were not in use; so, most of the information we have comes from what happened on Highway 11 during the eruption. In the months and years following the eruption, the vents and flows have been examined and mapped extensively, however. The eruption occurred along almost the entire length of the SW rift zone (from 8000 to 13,000 ft) and opened up almost simultaneously (like a zipper) from an essentially continuous vent system. Consequently, lava flows poured down at numerous places on both the west and east side of the rift. The eruption lasted only two weeks but the eruption of 1859 lasted almost a whole year. So, given that the flow volume is 4 to 5 times greater than the 1984 eruption (which lasted 3 weeks) it must have been a spectacular eruption. In places the flows were obviously very fluid and flowing rapidly, since they eroded the bases of prehistoric spatter cones during emplacement. It must have been coming downhill like gangbusters! The lava flow was compositionally very heterogeneous, with the upper part of the rift eruption evolved magmas (MgO 7 wt. %). Compositions became more primitive (MgO up to 10 wt. %) down rift. However, the lowest elevation flows were the somewhat more evolved (MgO 8 wt. %). The data are consistent with mixing of a relatively primitive magma with an evolved magma that may have been residing in the rift zone (this older magma has compositions very similar to the lava produced by the 1949 summit…

    Volcanos

    On March 10, 2011, I attended a campus wide experience that was showing a volcano documentary by Maurice and Katia Krafft. They were born and raised in France and would like to retire in Hawaii. They are writers, movie makers, and scientists. In 1988, they circled the globe 8 times to study the many volcanoes of the earth. They love to photograph the many shield volcanoes in Hawaii because they are constantly erupting. To them, their perfect paradise is described as a lava lake not a paradise with crystal clear waters and sunny skies. They were attracted to fire since Maurice was 8 and Katia was 14. They transformed their passion to a way of life.…
