“Human Response to Volcanic Hazards is the Same Everywhere” Discuss this statement

Each year, there are approximately 60 volcanic eruptions across the globe. It is extremely difficult to predict the exact location, ferocity or timing of a volcanic hazard, therefore risks are imminent and potentially dangerous. A volcanic hazard comes from tectonic plates (large rigid blocks of the earth’s surface which appear to move as a unit) colliding with each other or moving apart, disrupting the ground beneath us, allowing magma to rise up through the crust. Hazards are events, natural or man made, that affects human life, property or activity. A response is the methods that humans take to reduce future risks, or prevent damage during in a hazard. Evacuation plans are in place in both MEDCs and LEDCs, however a lack of education about hazards and human resistance to government advice can have implications on responses.

Evacuation plans can be put into place in order to respond to hazards. One such example is used in the Bay of Napoli, Italy where the volcano Vesuvius is active. There are 3 zones; Red, yellow and blue. The red zone is subject to the most danger, including pyroclastic flows, gases, landslides and ash. There is a population of just under 550mila living in this zone, therefore if an eruption is highly anticipated, then the entire area will be evacuated as soon as possible. The yellow zone will most likely be affected by only pyroclastic particles, such as ash, and it is estimated that only 10% of this region is actually at danger. The blue zone is within the yellow zone, and at risk to floods as it consists of the Valley of Nola. By having a structured and detail evacuation plan in place, those living in potential risk areas have their chances of human damage reduced, as they can escape the area. Monitoring systems are in place which theoretically will give…...

Discuss the Statement: the Extent to Which Earthquakes Present a Hazard Depends on Where They Are Experienced.

...Geography 40 mark EQ question Discuss the statement: The extent to which earthquakes present a hazard depends on where they are experienced. (40 marks) A Hazard is best defined as a situation that’s ‘a potential source of harm or adverse health effect on a person or persons’. An earthquake is a tectonic event which can be a huge hazard to people- particularly effecting areas of the earth around convergent, divergent and transform plate boundaries: in both MEDC’s and LEDC’s with equally force. Hazards earthquakes cause can be divided into two sub-categories: primary and secondary effects. Primary effects are the problems that are of direct result of the seismic waves, including effects such as liquefaction, tsunamis and landslides. Primary effects then lead to secondary effects; floods, fires, disease and even malnourishment. However a number of factors can dictate whether these effects present a hazard to people or not- location, whether in a MEDC or LEDC, can dictate the severity of the hazard. To start, I want to highlight the difference in the primary effects of an earthquake. Comparing the factors like death and injuries- or social effects- and then the environmental effects in looking at the destruction of infrastructure experienced in varying parts of the world. To highlight this difference of place: using an EQ in a LEDC and one in a MEDC. So looking at deaths and injuries we can see as an overall trend there tends to be more deaths caused form the initial...

Volcanic Hazards Management

...Volcano Hazards Management 1. Prediction * Long term * Short term LONG TERM PREDICTION * Using recurrence intervals to estimate the next volcanic eruption based on past occurrences and trends. This recurrence interval method is generally not effective for a number of reasons: a) for certain volcanoes, there has been a lack of information of past occurrences, such as the type and frequency of eruptions, to effectively predict the overall behavior of the volcano and b) it is impossible to determine exactly what time frame the volcano may erupt. Example: The US Geological Society also estimated that Mt St Helens may experience another eruption in the next 20-30 years, but such a large time frame is useless in giving governments any accurate information for the preparation of the eruption or mitigation. The 1985 Nevado del Ruiz volcanic eruption was predicted in 1979, quite accurately, however, the damage to the country was devastating as the government did not take the appropriate mitigation measures. 25 000 people and 15 000 animals were killed. 4 500 people were injured, 8 000 people homeless. Some government officials dismissed the report as too alarming and did not want to evacuate people till they were assured of the necessity. A group of scientists visited the crater, saw nothing to suggest eminent danger and did not recommend and evacuation. No emergency plans were made to evacuate people After the Mt Nevado Del Ruiz eruption in 1985, it was......

...`Volcanic and seismic events are major pieces of evidence towards proving that plate tectonics is valid' Discuss the extent to which you agree with this statement. The theory of plate tectonics states that the Earth's lithosphere is fragmented into a dozen or more large and small rigid sections called plates that are moving relative to one another as they float on top of the underlying semi-molten mantle. If we map out the divisions between these plates, it would correlate significantly with the distribution of volcanoes around the world. These plates are either continental (The North American Plate), or oceanic (The Nazca Plate). Tectonic plates are powered by convection currents, which is the circular movement of magma within the mantle. These currents are powered by the core, which heats the magma, causing it to rise, cool and fall back down. This circular motion causes the plates, which float on the mantle, to move. The entire outer surface of the planet is divided into these plate formations, roughly 30 in total, which vary in size from over 100,000,000 square miles for example The Pacific Plate to the Galapagos micro plate at 12,000 square miles. The individual plates are separated by fault lines which extend from the surface all the way to the asthenosphere, at which point the fault disappears due to the plasticity of the rock that exists there. The earth's plates are moved by convection currents in the mantle caused by localised concentrations of radiation and......

Discuss the View That the Impact of Earthquake Hazards Depends Primarily on Human Factors

...and North American plates which move at 5-9 cm/year and 2-3 cm/year respectively causing the 1994 Los Angeles earthquake along the San Andreas fault alongside which lies the San Gregorio and Hayward faults. Earthquakes have different impacts dependent on the location of their foci, the point at which they originate from underground, the presence of land in the surrounding areas, but also the human factors such as land use, population density and the use of earthquake proofing technologies to limit earthquake impacts. The Boxing Day tsunami in 2004 was created due to an earthquake along the 3 plate junction where the Philippine, Pacific and Eurasian plates all meet. The 15-20 m slip along a 1600km slip plane created an earthquake measures at 9.1 on the logarithmic Richter scale making it one of the most intense earthquakes in history. It caused a tsunami wave which resulted in the deaths of 180000 people according to a UN report, though other sources suggested it reached 300000. The Kobe earthquake which devastated the port of Osaka Bay resulted in 6300 deaths and 35000 serious injuries. This earthquake measured 7.1 on the Richter scale meaning that it was less powerful as each step up the scale is a 10 fold increase in power and a 30 fold increase in intensity. The impacts in terms of death were vastly different as a result of the lower reading on the scale and therefore it can be argued that natural factors such as the origin of the earthquake and its force are important......

Humans Are Far Too Independent on Oil, Discuss This Statement

...Human are far too dependent on oil to what extent do you agree with this statement. As Fossil Fuels Dominate the Global energy situation, oil provides 34.8% of the world’s Energy being the number one source of energy in 4 out of 6 regions, especially in the Middle East with 50% and is also the number one extractor and exporter of oil. Oil Dependency is when a country is in need of oil to be able to function properly and without oil, it may crumble. Oil is the biggest single source of the world's energy. In the short-term vital public services like ambulances, fire-engines and public transport are all put in jeopardy when fuel supplies run low. The U.S. is the largest consumer of oil in the world, burning through 18.83 million barrels per day. Even if the U.S. produced all petroleum products domestically, Americans would still feel the shocks from market volatility. Oil is a global market, and market prices prevail regardless of origin. Despite policies to improve vehicle efficiency, America remains dependent on oil. This dependency presents several problems, especially in the long term. And it has happened before, The 1973 oil crisis began in October 1973 when the members of the Organization of Arab Petroleum Exporting Countries proclaimed an oil embargo in response to American involvement in the 1973 Yom Kippur War.  The US supplied Israel with arms. In response to this, OAPEC announced an oil embargo against Canada, Japan, the Netherlands, the United Kingdom and the US.......

Natural Disasters Are Not Often Natural Disasters but Are in Fact Human Disasters’. Discuss This Statement in Relation to Seismic Events. (40)

...any human influences causing it. Whereas a human disaster is an event that was influenced by human activity, making the impacts to people and the environment worse. Natural disasters are due to the nature of the disaster that cannot be changed or reduced in any way. One factor that supports this is the magnitude of the earthquake. Eg. Haiti earthquake of 2011 had a magnitude of 7.2 on the Richter scale. whereas Japans was a magnitude of 9.0. The higher magnitude would cause greater impacts such as destruction of infrastructure and greater deaths. This is proven as Japan had 18,000 lives lost. Therefore showing that the nature and physical aspects of a disaster is what influences the impacts of the event. However, it can be argued that human factors have more influence on impacts of an event due to Haiti having a greater number of deaths overall due to being an LEDC and so lower economically developed. Whereas Japan is a MEDC. This means that there may be less technology to attempt to mitigate the impacts to the people such as warning systems being set up and the level of medical care and education. Eg. Haiti had an overall death toll of 60,000 that died with 350,000 infected with cholera due to poor sewage treatment and hygiene. The human activity caused the effects of the disaster to be worse due to contamination of the local drinking river of which people drank and washed in. compared to the 10,000 that died in Japans earthquake, it suggests that it is in fact a human......

...“Volcanic and seismic events are major pieces of evidence towards proving that plate tectonics theory is valid”. Discuss the extent to which you agree with this statement. Plate tectonics is the theory that suggests that the Lithosphere is separated up into approximately twelve plates that can be moved around via convection currents, changing the land and sea formations across the globe. Since interest began during the early 20th century a variety of propositions have been put forward to suggest the existence of plate tectonics. The most prominent of these theories is the existence of seismic waves and volcanic activity, especially the location and distribution of these. Along with these theories is the discovery of fossils and their locations across the globe, as well as the shape of the existing continents and the “jigsaw” theory. During the 17th century Francis Bacon noted that the West coast of Africa and Europe coincidentally looked as though they would fit with the East coast of the Americas. However, Bacon had little evidence for this theory, meaning it was swiftly forgotten. During the 1920’s, Alfred Wegner, proposed that the formation of the continents today has occurred via continental drift. However, Wegner goes on to suggest that 300 million years ago there was a single landmass, commonly known as Pangaea, as shown in Figure 1.1. Pangaea was one supercontinent that existed during the late Palaeozoic and carrying on into the early Mesozoic eras. It consisted......

Is There a One Size Fits All Approach to Dealing with Volcanic Hazards? 10 Marks

...In an MEDC, this statement would apply more suitably as the money available to invest in the prediction and mitigation of volcanic hazards is greater. Because of this, certain impacts such as lava flows (especially Rhyolitic) can be prepared for more effectively with diversion flows etc. also in an MEDC there is more likely to be a standardised model for coping with a volcanic hazards. For example in Japan there are school classes on dealing with an eruption and what to do when it does occur. However, what cannot be dealt with before the eruption occurs are hazards such as pyroclastic flows and ash/tephra cloud as these are unpredictable in their spread apart from when previous eruptions indicate where a pyroclastic flow may be directed. To deal with these types of immediate hazards, there must be quick response to areas affected to try and help those affected. In an ideal world, there could be a ‘one size fits all’ approach to post-eruption impacts but this is not possible as LEDCs on the whole do not have the money or resources to create such a fast reaction service. For example the eruption of Mount Pinatubo in 1991, the locals were notified of the eruption due to the fact there were 2 US military bases in the vicinity. If it were not the case, it is probable that the LEDC government would not have been able to prepare and respond as effectively. All volcanic eruptions are not the same however as is shown on the volcanic explosivity index as different volcanoes display......

“Natural Disasters Are Often Not Natural Disasters, but Are in Fact Human Disasters” Discuss This Statement in Relation to Seismic Events.

...disasters are not caused by humans they are caused by natural events however they can be considered human disasters as human actions can interfere with nature and often exaggerate the effects of the disaster. Although natural disasters can really only be classed a disaster if it affects humans as otherwise its impact would not necessarily be relevant so in effect all natural disasters are in effect human disasters. Seismic events, otherwise known as earthquakes, are a sudden violent shaking of the ground typically causing, as a result of the movement of tectonic plates in the earth’s crust or volcanic action. The result of seismic events is often destruction of buildings and infrastructure, which can claim many lives, thus often making them human disasters as they have such a grave impact on the human population. Although, location influences the impact seismic events have upon humans as the more populated the area the more lives that are likely to be lost, and whether the event occurs within an LEDC or an MEDC as the death rate due to a seismic event is likely to be higher in an LEDC than an MEDC. This is due to a multitude of factors including the strength and quality of buildings and infrastructure and the knowledge to prepare for large seismic events, as well as the resources available to respond to any disasters that may occur. Planning for a seismic event can have a huge impact on to what extent a natural disaster is also considered a human disaster, as if a country......

Discuss the View That the Impact of Earthquake Hazards Depends Primarily on Human Factors

...“Discuss the view that the impact of earthquake hazards depends primarily on human factors (40)”.  I agree to some extent about the statement above and that human factors can affect the impact of an earthquake hazard. A hazard is an object or process that has the potential to cause harm. Ground shaking, ground displacement and flooding are some of the hazards that are produced during an earthquake. In relation to the question above the type and severity of the impact can be affected by physical factors (such as the magnitude and frequency of the quake) as well as human factors (population density and education). I will be discussing the question using the following case studies, Sichuan, Indonesia and L’Aquila. On the 12th May 2008 an earthquake occurred at 2:28pm in Sichuan because the pressure resulting from the Indian plate colliding with the Eurasian was sent along the Longmenshan fault line that runs through Sichuan. The earthquake lasted 120 seconds and reached 7.9 on the Richter scale, one of the deadliest to strike China in recent years and its effects were felt as far away as Taiwan, Thailand and Bangladesh. Although the area has a long history of tectonic activity, it seems it was not prepared for an event of this magnitude. With a population consisting of 87.26m people the death toll stood at nearly 70 thousand along with 374,000 people injured and 5m left homeless. Making this Chinas worst earthquake since 1976 when 240,000 people were killed in Tangshan.......

‘Natural Disasters Are Often Not Natural Disasters, but in Fact Human Disasters. Discuss This Statement According to Seismic Events’

...‘Natural disasters are often not natural disasters, but in fact human disasters. Discuss this statement according to seismic events’ Seismic events are occurrences in which energy is briefly released in the Earth's crust, resulting in a series of seismic waves which move through the crust. In some cases, the energy can be intense enough that it is felt in the form of an earthquake, while in other seismic events, the energy is so mild that it can only be identified with specialized equipment. A human disaster is an event directly and principally caused by one or more identifiable deliberate or negligent human action. Whereas a natural disaster is a natural event such as a flood, earthquake, or hurricane that causes great damage or loss of life. A disaster is often considered a human disaster if it has been caused by human interference or activity that has made the threat of seismic events worse, by measurements such as amount of deaths or cost to an economy. In every day society humans take shortcuts in the process of construction or urban planning with the short term benefits of saving time and money. However sadly this means the standard of resistance buildings have against seismic events is not enough to withstand the pressures they bring, such as the ground moving or liquefaction. Generally in MEDC’s at risk of earthquakes buildings and the landscape is often built to be earthquake ‘proof’ but only up to a certain magnitude, meaning of a rare earthquake above the......

Discuss the View That the Income of Volcanic Hazards Depends Primarily on Human Factors

...A volcanic hazard refers to any potential dangerous volcanic process from primary hazards; such as lava flows, pyroclastic flows, ash falls or volcanic gases and also secondary hazards; including lahars and volcanic landslides. There are around 1500 potentially active volcanoes worldwide and therefore in my opinion, every volcanic eruption is unique and influences the hazards that are produced from it which will impact upon the environment, the economy and the population of an area. Although it can be argued that physical factors; like the magnitude, cause and give the greatest input into the initial impact, the human factors also have an influence on the effects a hazard can have, for instance the land use and demography. The vulnerability of LEDC’s (Low economically developed countries) has a large effect upon the response and recovery to a volcanic eruption. The Nevada Del Ruiz volcano erupted in 1985 and left devastating impacts as a result of the demography; such as the densely populated areas surrounding. The pyroclastic flows and melting glaciers that created lahars killed 22,000 people and 150,000 animals due the speeds of the hazards travelling at 50km per hour; mostly suffocating those that died. However as well as this there were many long term impacts that had a huge influence due to the destruction of basic needs and services that the LEDC’s primarily relied heavily on; the whole destruction cost the government $7.7 million. Therefore international aid (the......

‘Discuss the View That the Impact of Volcanic Hazards Depends Primarily on Human Factors.’

...To discuss this view there is a need to understand what a hazard is and what are the volcanic hazards. A hazard is something that causes danger or risk. In the case of volcanic activity it is an event which can cause risks to human life or the surrounding environment. There are specific hazards which occur with volcanic eruptions such as pyroclastic flows, lava flows and the gas emissions from the volcano however there are also secondary hazards that can occur such as lahars, landslides and tsunamis. These are all natural however, the impacts can be worsened by human activity. The impact on humans depends on the amount of human activity surrounding the volcano and the human activity which occurs within the greatest risk area. Around the world, volcanic events can vary in both size and frequency this can be down to the type of plate boundary that the volcanoes lie on but also the type of lava that is known to that volcano. It can be argued that the volcanic hazards depend on the physical factors rather than human factors. For example the eruption that occurred in Iceland in 2010. There were 2 phases which had distinct physical differences and this then affected human activity in a number of different ways. Eyjafjallajökull’s first eruption occurred on the 20th March 2010 and it lasted 6 weeks. It didn't gain much interest from world wide media due to the fact there wasn't any explosive events which affected other parts of the world. This was down to the fact the lava that......

...Exemplar (37 Marks)-“Volcanic and Seismic events are major pieces of evidence towards proving that plate tectonics theory is valid” Discuss the extent to which you agree with this statement. (40 Marks) The theory of plate tectonics is a relatively new idea – only conceived and developed within the last 100 years and is now generally accepted as the explanation for the causation of earthquakes and volcanoes and where they occur. It has now replaced the theory that tectonic events are caused by god in most western countries. The theory of plate tectonics was first developed by Alfred Wegener in 1912. He saw that the continents seem to have a jig-saw fit e.g. Africa and South America coastlines fitting together, suggesting that they were at one time joined together as part of a super continent called Gondwanaland and the other super continent Laurasia was in the north. Later evidence supported this – the fossilised remains of a dinosaur, the mosasaurs, was found on the coasts of Brazil and Gabon. There were also the same fossilised pollen species and rock sediments on these coastlines. Wegener’s ideas, though simple, were proved further right and built upon which further increased our understanding of tectonic events. Sea floor spreading was discovered showing that rock is being created and destroyed, leading us to believe in the existence of plates and plate boundaries. Sea floor spreading was shown in the Atlantic, where it is believed the Eurasian and North American......
