Narcondam Island
Narcondam or Narcondum is a small volcanic island located in the Andaman Sea. Its central peak rises some 710 m above mean sea level, and is formed of andesite. It is considered to be part of the Andaman Islands, the main body of which lie approximately 114 km to the west. The island is part of 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
The Blackfoot diatreme is a diatreme in southeastern British Columbia, Canada, located 60 km (37 mi) northeast of Cranbrook. It is 1,000 m (3,281 ft) in length with a maximum width of 400 m (1,312 ft). The diatreme is elongate in shape, and outcrops east of Blackfoot Creek.
Ibex Mountain
Ibex Mountain is a young cinder cone in the Yukon Territory, Canada, located 33 km southwest of Whitehorse and 12 km southeast of Mount Arkell. It is in a group of basaltic cones and lava flows called Alligator Lake and is in the Northern Cordilleran Volcanic Province. It is believed Ibex Mountain last erupted during the Pleistocene.[1] Ibex Mountain is at the head of the Ibex River, which is southeast of Whitehorse. There is a road that runs close to Ibex Lake on the southeast side of the summit. From there is the hike to the summit of the cone.

Volcano Tour Destination

...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......

Volcanoes

...The name "volcano" has its origin from the name of Vulcan a god of fire in roman mythology. What is a volcano? A volcano is a mountain (landform) that opens downward to a pool of molten rock below the surface of the earth. When the pressure builds up, eruptions begin. Gases and rocks shoot up through the volcano centre and spill over with lava. Eruptions can cause blasts, lava flows, hot ash flows, mudslides, avalanches, falling ash and floods. Volcano eruptions have been known to knock down entire forests. An erupting volcano can trigger tsunamis, flash floods, earthquakes, mudflows and rockfalls. How are volcanoes formed? Volcanoes are formed when magma from within the Earth's upper mantle works its way to the surface. At the surface, it erupts to form lava flows and ash deposits. Over time as the volcano continues to erupt, it will get bigger and bigger. What are the different stages of volcanoes? Volcanoes are in three main categories: active, dormant, and extinct. An active volcano is one which has recently erupted and there is a possibility that it may erupt soon. A dormant volcano is one which has not erupted in a long time but there is a possibility it can erupt in the future. An extinct volcano is one which has erupted thousands of years ago and there’s no possibility of eruption. Why do volcanoes erupt? The Earth's crust is made up of huge slabs called plates, which fit together like a jigsaw puzzle. These plates sometimes move. The friction causes......

What Is a Volcano

...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...

Volcanic Threats in the Us

... Volcanic Threats in the United States Volcano eruptions cost the United States quite a lot of monetary values, as a result of damage to properties. In the United States there are up to sixty active volcanoes, some explosive and others non-explosive. Mitigating the effects of the volcano eruptions is important to reduce future deaths and damage. This essay considers possible ways of mitigating the future damage and deaths from volcano eruptions, as well as the volcano risk areas in the United States. The first step in mitigating the effects of volcanoes is establishing high technology detection systems that will forecast possible volcanoes activities. There are many seismic data collecting systems designed to monitor the activities of magma and the volcano sites. However, these systems ought to be upgraded into to newer technologies to ensure efficiency in forecasting volcano eruptions (Aditya, 2014). In addition, the findings of these systems ought to be taken with weight. Failing to act upon the indications from such systems marks the beginning of volcano eruption dangers. Therefore, it is not only a matter of establishing systems, but ensuring that they are functional and acting upon their findings. Secondly, timely warnings of possible eruptions will assist people to keep safe distances from the volcano eruption. It is inevitable to warn people when volcano activities indicate possible eruptions in the near future. For......

Volcano

...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. ...

Volcano in Montserrat

...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.

Earth Science

...top of a towering volcano, they do not share the entire story of volcanoes Magma and Lava * So what exactly is a volcano? Well, it can be defined as a vent in the earth's crust through which lava, rock fragments, hot vapor and gases are ejected. In other words, a volcano is the earth's way of letting off a little steam. * The super-heated particles that eject out of a volcano come from deep below the earth's surface where temperatures can become so hot that rock actually melts. Magma is the term used to describe this hot molten rock from deep within the earth. * A volcano begins to form when magma, which is less dense than the rock it originated from, rises toward the earth's surface. This liquid rock collects in chambers called 'magma chambers,' where pressure builds due to expanding steam and gases associated with the magma. As pressure reaches a peak within these chambers, magma finds its way through a vent or fissure in the earth's surface, resulting in a volcanic eruption and the expulsion of the hot molten rock. * We now have hot molten rock outside of a volcano, and its name changes from magma to lava. So you can think of 'magma' as liquid rock in the 'middle' of the earth and 'lava' as liquid rock that's 'leaving' the earth. Origin of the Name Volcano * When a volcano erupts, it expels lava, gases and rocks with tremendous force. It's no wonder that the Romans thought that volcanoes were the work of the gods. The name 'volcano' comes from a......

Tungurahua Ecuador

...strato volcano located in Ecuador. This volcano is caused by subduction, as the Nazca pate slides below the South American plate. It is one of South America’s most active volcanoes, as of today. A strato volcano is a majestic volcano. It does not erupt often and when it erupts it has very high silica levels. Tungurhua has disproved the concept that strato volcanoes do not erupt often. Their lava flows are very thick and slow. Ever since the volcano started erupting more frequently in 1999 the ice cap of the volcano melted away. Tungurahua reaches a height of 5016 meters, and it is some 25 kilometers from Ambato. Ambato is Ecuador’s fourth largest city, and it is the beautiful city my mother is from. Every time I visit Ecuador I can see the volcano clearly from the porch of my house. The eruptions from the volcano have caused terrible damage to the cities that surround the volcano. One major city that has been the most damaged is Banos. Banos is one of the most popular tourist attractions that Ecuador has. Its natural beauties and beautiful climate are some things that make the city very attractive. Sadly, Banos is located vey close to the active volcano of Tungurahua. The volcano has been erupting every two years or so ever since 1999. When Tungurahua erupts, Banos is the city that mostly everyone has to evacuate from because it is so close to the volcano. The explosion the volcano creates is so loud and there are avalanches of molten rock being shot out of the volcano.......

Natural Disasters and Business: the Impact of the Icelandic Volcano of April 2010 on European Logistics and Distribution – a Case Study of Malta

...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...

Volcano

...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......

Newberry Caldera and Vicinity

...Newberry Caldera: Oregon’s largest Volcano Volcanology Term Paper Figure 1: View of Newberry Caldera from Lava Butte. Photo by Lee Siebert, 1995 (Smithsonian Institution) Newberry Caldera Newberry volcano, situated east of the Cascade Range is one of the largest volcanoes in terms of its area in the lower 48 United States and is also the largest volcano in Oregon, covering an area of about 1600 sq. km. The low angle basaltic to basaltic-andesite composite shield is dotted with over 400 cinder cones; however the volcano also has a history of producing a number of major silicic eruptions, which are associated with the formation of the 6 by 8 km wide summit caldera that contains two caldera lakes. Despite the similarities, Newberry in fact is not a cascade volcano. Instead it belongs to a discontinuous belt of composite volcanoes lying parallel to the Cascades at a distance of 56-80 km. this discontinuous belt extends up to Mt. Simcoe east of Mt. Adams and south to Medicine Lake Volcano east of Mt. Shasta (Williams, 1935). Figure 2: aerial view of Newberry Caldera. Photo by Lee Siebert, 1998 (Smithsonian Institution). The earliest eruptive products (<0.73 million years ago) (Ma) consist of a sequence of ash-flow and airfall tuffs. Caldera collapse is thought to be associated with major ash flows emplaced about 0.5 and 0.3-0.5 Ma. These eruptions were preceded by the emplacement of numerous mafic cones and vents and silicic lava domes and flows, many of......
