Volcanologists study the volcano's eruptive history or install the proper instrumentation on a volcano well in advance of an outbreak, and continuously monitor and adequately interpret data coming from that equipment. However, scientists have difficult forecasting volcanic eruptions, and will still have difficulty forecasting future volcanic activities accurately. Most volcanoes have been dormant for many years, and do not work to a timetable and do not occur regularly, or have any form of pattern to them. Besides, some modern scientists have fail predicting volcano eruptions and warning evacuations. For example, on 2 May 2008, a massive explosion occurred unexpectedly at the concealed Chaitén Volcano in Chile’s southern volcanic zone (Carn
Hawaii a huge tourist hotspot due to its lovable culture and beautiful landscape, is home to the volcano Hauna Loa, considered the largest volcano on the earth, located on the island of Hawaii which also holds four others is currently sleeping after its rude awakening roughly thirty years ago but it’s not certain when she might erupt again. Mauna Loa takes us more than half, due to technology that has been so fine-tuned that it could predict an eruption months before the actual event. There was a scare about ten years ago where scientist believed it could definitely erupt due to the amount of magma going into the magma chamber, but miraculously the magma camber was expanded and created more room for the magma to collect in. Another eruption
Analyse the factors that causes differences in the hazards posed by volcanoes around the world (40 marks)
● This was the first time this type of volcano eruption was actually witnessed and
A hazard is a situation that poses a level of threat tolife, health, property or environment. The level of hazard posed by different volcanoes can very greatly, from a weak eruption with minimal impact that causes little damage, to a voilent and life threatening explosion. Most of the sixty-plus volcanoes that erupt each year are low risk, however a combination of factors can cause a volcano to be a serious hazard. The factors causing these variations will be explained in this essay.
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
A particular vulcanologist, Frank Trusdell who is working for the USGS Hawaiian Volcano Obsevatory (HVO), have been studying the historic eruptions of Mauna Loa for the past 3 decades. Trusdell mentioned that Mauna Loa erupt at a long term average of once every 6 years. Currently, there are not much activity by comparing the seismic activity in 1980-1984 to 2011-2014. When a volcanic eruption is imminent, the HVO will alert the Hawaiian emergency management agency and civil defense officials in full emergency mode. Necessary evacuations will be organised for residence and so as broadcasting live alerts through TVs and radio stations. Also, status, reports and HVO websites of the volcano’s activity will also be constantly updated to make sure
Have you ever been near a volcano when it erupted? Most of us haven't, but if you're unlucky enough, you just might have. Many people think it would be cool, but it is indeed not. In fact, the people of Pompeii were very unlucky when Mount Vesuvius erupted in 79 AD. Nearly two-thousand people died. Although that eruption was very similar to the 1980 eruption of Saint Helens, it was also very different.
Albeit no emissions of magma or volcanic cinder have happened for some a large number of years, future ejections are likely. In the following few hundred years, risks will most likely be restricted to continuous fountain and hot-spring action, incidental steam blasts, and moderate to vast quakes. To better comprehend Yellowstone's well of lava and quake risks and to help ensure people in general, the U.s. Geographical Survey, the University of Utah, and Yellowstone National Park structured the Yellowstone Volcano Observatory, which persistently screens movement in the
Puyehue volcanoe was gushing lava in Chile eruption on Saturday 4 June 2011 following 51 years of inactivity. On the 3th June a seismic swarm happened with 1450 quakes enlisted at the volcano of gushing lava, related with magma development under the fountain of liquid magma. The seismic tremors has a concentration of 2-5 km profundity on the southeast flank of the fountain of liquid magma. On Saturday fourth of June the well of lava alarm was raised to level RED after a checked increment in seismic movement. The dangerous ejection at Puyehue well of lava started on Saturday fourth June delivering a 10 km high fiery debris section. More than 600 individuals were emptied from the range. Volcanic fiery debris fell in the city of
Volcanoes are one of the most destructive, yet, most beautiful things on Earth. They can make a famous city choke in its own ashes in one day, like Pompeii. Or they can turn a once damaging mountain into a graceful and peaceful home for new life, like Mount St. Helen’s. All volcanoes are unique, and no two are the same. Some erupt differently than others, some look different than others, and all are located in different spots all over the world. I learned this while completing the project and the five volcanoes I researched are examples of my discoveries. The five volcanoes I researched were Mount Hood, Mount Mageik, Long Island, Mount Muria, and Las Pilas.
According to the Geological Association of Canada, volcanology is the study of volcanoes and in particular the way in which volcanoes erupt. Volcanologists investigate the processes that go on inside the Earth that lead to volcanic eruptions. Their work involves the study of the movement of magma and the surfaces of volcanoes, particularly their gas content. Volcanologists also study the interior of volcanoes because it reflects the importance on how the Earth work.
The volcanoes are located where there is a divergence or convergence in the tectonic plates and bring their lava from the deepest of the terrestrial mantle. The materials and explosions of these ginates represent a constant risk in the places inhabited by the human being, nevertheless the people ususually live in these areas no matter the risk. On the other hand the volcanos can change the geology of an impressive form, or to cool the temperature of the earth, or to darken the sky. The scientific community increases its efforts to try to understand better what happens in volcanoes, however it is impossible to predict these conditions.
Stratovolcano and Shield volcanos are naturally occurring ruptures in the earth’s crust. They have been a part of our history for nearly 6,000 years and some say that they have been around longer than dinosaurs. While these events are rather cool to watch, they are known to be some of the most devastating natural disasters known to man. Volcanic hazards and eruptions continue to happen throughout the entire world and crisis aversion is something that is becoming more and more important.
This is only a general overview of the inner workings of volcanoes and their eruptions. For more infomation, visit Volcano World -- The Premier Source of Volcano Info on the Web.
Volcanos are deadly, can form on islands or mainland, and can destroy mountains and cities. Volcanos commonly form from holes in the earth containing magma. When pressure builds up in these magma chambers, they explode resulting in magma and rock catapulting out into the air. As these volcanoes repeatedly explode, they leak magma, which runs down the side of the volcano. Eventually, the lava cools and transforms into solid rock, building up the volcano to mountain size. An example of giant volcanic eruptions is the Pompeii disaster in 79AD, when Mount Vesuvius erupted and destroyed all of Pompeii. Another example includes, the 1980 eruption of Mount St. Helens in Washington state, which destroyed the whole mountain. Volcanos
