...Volcano Video Part 1/2 Two geologists have been testing there hypothesis of volcanoes trying to predict when they will erupt. Cheutt has been using A/B types to forecast an eruption of volcanoes while Stan Williams uses gas to monitor sulfur dioxide from volcanoes to predict when they it will also erupt. Both geologists’ methods worked. In a situation, like a volcanic eruption, people shouldn’t sit around questioning about whether they should evacuate or not. People should hit the road because there is no time for answers when so many lives are in danger. If LA was in need of an evacuation, I feel that the government should send armies out to evacuate LA within 24 hrs. Minorities should make sure to take along plenty of waters, blankets, and other important necessities needed. However, I do not believe it is possible for everyone to evacuate because LA is not that small and there are complicated people out there who would stay. I believe volcanologists made irresponsible decision going into Galeras ignoring signs of an eruption putting there lives in danger. If I had to apply scientific method in action, my observation will be saving lives. The hypothesis will be A/B type or gases to predict volcanoes. The experiment will be Cheutt using seismographs to put to test while Stan Williams gets close to volcanoes to monitor sulfur dioxide. Even though both methods worked, Cheutt’s hypothesis was more accurate for forecasting when volcanoes will erupt because the seismograph...

...the Indian union territory of Andaman and Nicobar Islands. The island is small, covering an area of approximately 6.8 square kilometres.[1] It was classified as a dormant volcano by the Geological Survey of India. Barren Island (Andaman Islands) Barren Island (coordinates: 12°16′N 93°51′E) is located in the Andaman Sea, one of the most easterly of the Andaman Islands. It is the only confirmed active volcano in South Asia. Along with the rest of the Andamans, it is a part of the Indian Union Territory of Andaman and Nicobar Islands, and lies about 135 km (84 mi) northeast of the territory's capital, Port Blair. The first recorded eruption of the volcano dates back to 1787. Since then, the volcano has erupted more than ten times, with the most recent one which started in September 2010 and continued through January 2011. The Black Tusk The Black Tusk is a stratovolcano and a pinnacle of volcanic rock in Garibaldi Provincial Park of British Columbia, Canada. At 2,319 m (7,608 ft) above sea level,[3] the upper spire is visible from a great distance in all directions. It is particularly noticeable from the Sea-to-Sky Highway just south of Whistler, British Columbia. Distinctive and immediately identifiable, The Black Tusk is among the best known mountains in the Garibaldi Ranges of the Coast Mountains. The volcano is part of the Garibaldi Volcanic Belt which is a segment of the Canadian Cascade Arc, but it is not within the geographic boundary of the Cascade Range. Blackfoot diatreme...

...volcano A volcano is a place on the earths surface for any other planets or moons surface) where molten rock and gases erupt through the earths crust.Volcanoes vary quite a bit in their structure-some have rocks in the earths crust where lava erupts, and some are domes, shields, or mountain-like structures with a crater at the summit.Magma is molten rock within the earths crust.When magma erupts through the earths surface it is called lava. Lava can be thick and slow-moving or thin and fast-moving. Rock also comes from volcanoes in other forms, including ash (finely powdered rock that looks like dark smoke coming from the volcano) and cinders (bits of fragmented lava). Inside a volcano The magma chamber is a collection of magma inside the earth, below the volcano. The main vent is the main outlet for the magma to escape. secondary vents are smaller outlets through which magma escapes. The crater is created after an eruption blows the top off the volcano. An eruption occurs when pressure in the magma chamber forces magma up the main vent, towards the crater at the top of the volcano. some magma will also be forced out of the secondary vent at the side of the volcano. Different types of volcano Volcanoes can be described in terms of activity and can be: Still active and erupt frequently. Dormant (temporarily inactive but not fully extinct). Extinct (never likely to erupt again). Volcanoes can also be described by their shape or type. ...

...Impacts on the environment | Impacts on the people | Between 4 - 5 million cubic metres of lava was unloaded in the form of pyroclastic flows. This means that thousands of houses were buried all over the island by ash and rocks. Because the houses are buried people are outside with no shelter meaning they have to rebuild the houses, however there are no services so people have no jobs so are making no money. This meansthey are unable to build many homes to shelter people. | When the volcano shows signs of eruption people are required to leave to area for safety reasons. This means that anyone living near the are not guaranteed a stable life or stable farming. Because ofthis they were reluctant to farm meaning that thepeople of Montserrat had less food meaning theprices grew a large amount and in future possiblyhave to import food costing even more. | 10 villages(including Windy Hill, Brambles, Bethel,and Harris) were damaged or destroyed by deposits from the eruption e.g. pyroclastic flows,fine grained surge deposits, blocks and ash flowdeposits. This means that all vegetation has died leaving no food so people have to import food. | The helicopter could only reach places on the east side of the island where the wind was strong. To the west side where there was lots of ash in the air. The Montserrat Defence Force and the Montserrat Police Force went in vehicles to try and find any survivorsbut it took two or three days for all the survivors to be rescued from the area. This...

...Aloha! Greetings from Kilauea Volcano, located on the Big Island of Hawaii! As you can tell, the landscape is a sea of orange lava as far as the eye can see. Around 1,500 years ago, this region was inhabited by the natives of Polynesia, a region in Oceania (“Australia and Oceania: Physical Geography”). This polytheistic group believed that Kilauea was home to Pele, the goddess of all volcanoes. They would offer sacrifices to keep her happy. Also, when Kilauea would erupt, they believed that Pele was very angry at them. The Kilauea Volcano is a major tourist attraction that helps out Hawaii’s economy. Surprisingly, Kilauea was ranked number one on the top-rated tourist attractions in Hawaii, just after Waipio Valley and Overlook, a beach on...

...1. What is a volcano? A volcano is an opening, or rupture, in the surface or crust of the Earth or a planetary mass object, which allows hot lava, volcanic ash and gases to escape from the magma chamber below the surface. 2. How is volcano formed? Volcanoes form when hot material from below rises and leaks into the crust. This hot material, called magma, comes either from a melt of subducted crustal material, and which is light and buoyant after melting, or it may come from deeper in the interior of a planet and is light and buoyant because it is very hot. 3. What are the kinds of volcano according to shapes and activity? A. Kinds of volcano according to shapes: a. Shield volcanoes - broad, shield-like profiles, are formed by the eruption of low-viscosity lava that can flow a great distance from a vent. They generally do not explode catastrophically. b. Lava domes - are built by slow eruptions of highly viscous lavas. c. Cryptodomes - are formed when viscous lava forces its way up and causes a bulge. d. Volcanic cones or cinder cones - result from eruptions of mostly small pieces of scoria and pyroclastics (both resemble cinders, hence the name of this volcano type) that build up around the vent. B. Kinds of volcano according to activity e. Active Volcanoes - volcanoes that in general have been active for a certain period of time. f. Dormant Volcanoes - dormant volcanoes are assumed to be inactive for...

...Volcano tour destination The volcano site we will be visiting today is one of the most famous recent eruptions in North America. This volcano was on the watch list a couple of times in the last 3 years. We will be visiting Mount St. Helens located on the Pacific Northwest of the United States. This volcano is Skamania County, Washington. I recently had the opportunity to fly into the Seattle airport and witnessed this great volcano in all its grandeur. It’s located about 100 miles south of Seattle and just 53 miles north of Oregon. This Volcano is currently in an active status, meaning that it could erupt at any time. This volcano has a lava dome that is warm and steaming. There was concern recently that Mount St. Helens was due for another eruption. Television and news teams recently reporting that the lava dome is continuing to increase in size. It was about 3 years ago that the volcano started to awaken with some seismic activity. It would be interesting to witness Mount St. Helens erupt but of course we would like to do this from afar. Mount St. Helens is most famous for the large eruption in 1980. It was a Sunday morning, at 8:32 on May 18th that it last erupted. This was one of the most deadly and economically impactful eruptions in the United States history. The eruption lasted almost 6 weeks with continuous ash and steam being launched into the air. I don’t believe it was a surprise concerning this eruption. Many weeks ahead of the eruption the volcano...

...Guidebook for Aerial Volcano Formation of Aerial Volcano What is a volcano? What is a volcano? A volcano is a mountain that extends downwards to a pool of molten rock called magma below the Earth’s surface. When the pressure inside the Earth builds up, a volcanic eruption occurs. Magma shoots up through the opening and flows down the sides. Volcanoes can also spew volcanic ash when it erupts. What is pyroclastic flow? Aerial Volcano is an active stratovolcano that erupts pyroclastic flow. Pyroclastic flows are high-density currents of hot gases and volcanic fragments that move away from the volcano at a high speed. Pyroclastic flows can rush down the side of the volcano as fast as 100km/hour or more and reach temperatures as high as 1075°C. Pyroclastic flow is arguably the deadliest volcanic hazard. It is impossible to outrun. Those who get caught in it will be unable to breathe, and most likely burn to death. How was Aerial Volcano formed? Aerial...

...This volcano is the youngest in Hawaii. It is also 1 out of the 5 most active volcanoes in Hawaii. It is 60 km deep. The Kilauea Volcano is a shield volcano. The volcano got its name from the Hawaiian word meaning spreading or spewing. The last time it erupted was in November 2008. It reached sea level about 100,000 years ago but is between 300,000 to 600,000 years old. One of the major eruptions that has happened so far in 1790 killed about 80 people. The Kilauea volcano has had 62 eruptions so far. Its crater is 3,646 feet deep. Some of the hazards that come with this volcano are small earthquakes, lava entering the ocean which could harm some animals, volcanic gas, and explosive eruptions. It’s caldera is believed to be the volcano goddess...

...Yellowstone super volcano, its northwest Wyoming and northeast Montana. No one has died, but if you are around when this explodes, you won’t be around much longer. It melts the lithosphere, this makes a giant soup of nukes and when it goes off it will be very powerful. If you put Tokyo in the Yellowstone volcano (caldera) there will be a lot of space left over. Then there is some bad things that might happen, now you might be thinking “save the children!”, it's not going anytime soon. Maybe 30,000 years, that's a long time right, but if you are around at this time. Here some potential effects of the Yellowstone caldera it will cause 1000 cubic kilometers of ash to go into the air, it will also kill a lot of the people in the north west,...

...Causes What are the causes of the hazard? Volcanoes are formed when Magma rises from the upper mantle towards the Earth's surface. This process can be assisted by seismic activity or a variety of thermal driven phenomenon. As early as November 1984, increased levels in seismic activity were observed by geologist near Nevado Del Ruiz. Due to this increased activity, geologist became more observant of events, even if minor. In November 1985, the volcano began releasing gasses that were rich in sulfur dioxides and elementary sulfurs. The excessive amounts of gasses released from the volcano caused the pressure to build within which lead to the explosive eruption at 3:06pm, November 13th. How and why did this specific hazard occur? Due to the...

...Indonesia May 29, 2006 By: Yulini Arediningsih Abstract This paper overview the occurrence of Sidoarjo mud flow, known as Lusi Mud Volcano, the world fastest growing mud volcano, triggered by gas drilling exploration. Since May 29, 2006, Lusi mud volcano in Porong sub-district, East Java, Indonesia has been spurting voluminous hot mud and gas, with uncertain knowledge when it will cease. The progressing eruption has been causing major impact on human life, social, economic and environment in this highly populated region. Breached regulations including Indonesian regulations, constitutions, and APPEGGA rules of conduct are outlined. There are five critical concerns related to ethical and professional conduct arising from the occurrence of Lusi mud volcano. The concerns include negligence to best practise procedures, particularly drilling in high pressure zone; conflict of interest between public, government and private sector; violence to human right, public safety; and crisis management related to mitigating the impacts on environment, social, economic especially in compensation process to the victims. 1. Introduction Sidoarjo/Lapindo Mud flow, is geologically identified as a mud volcano (Sawolo, et al 2009). It is generally known as Lusi, a short name of Lumpur Sidoarjo. Lumpur means mud in Indonesian language. Lusi mud volcano is located in Porong sub district, Sidoarjo Regency, East Java Province, Indonesia. It is located about 30 km south of Surabaya, capital...

...Volcano Disaster Assistance Program: Pros and Cons The Volcano Disaster Assistance Program was formed in 1986 in response to the devastating volcanic mudflow caused by an eruption of Nevado del Ruiz volcano in Colombia. The mudflow destroyed the city in 1985, killing more than 25,000 people. Unfortunately, the tragedy was preventable. Better education of the local population and clear communication would have allowed warnings to be received, understood, and acted upon prior to the disaster. Volcanologist is the expert that works monitoring the activity of the volcanoes to prevent any disaster. The volcanologist’s work has direct importance to the lives of people who live near to the volcanoes but also it is a high-risk job for their own lives. There is no room for any mistake. As a result the volcanologist’s job requires an educational preparation and training to develop the functions. In addition, there are another pros and cons of working as a volcano expert and it is my purpose to develop some of them along this essay....

...During one week in April 2010, distribution of packages and cargoes by air were grounded throughout Europe, as the eruption of a maj or series of volcanoes sent toxic and metallic particles into the air in the form of gas clou ds. Most airlines operating in the affected area, anxious to comply with safety rulin gs, suspended all flights during this time. The major ‘express’ logistics and distribution companies – such as TNT, FedEx and DHL – were profoundly affected. Most packages fo r TNT, for example, are sent to a distribution hub in Leige, in Belgium. This hub became log- jammed and undelivered packages accumulated. In a study of the impact on the island of Malta (conducte d by an MSM MBA student from intake 26 as research for an MBA thesis), it was d iscovered that an entrepreneurial approach – by using sea-based deliveries also incorporating land- based trucking services – enabled TNT to steal a march on its competitors. Although taking two or three days to make deliveries that might n ormally take one day, TNT were able to keep their packages moving, when their com petitors’ packages were holed-up in Leige. Otherwise packages were hand-carried on commercial airlines – anything to solve customer problems. Customers won f rom the competition were so impressed by the responsiveness and flexibility of TNT in Malta that they were subsequently...
