Explore the physical causes of tectonic hazards, including the significance of differing plate boundaries and other factors.
Research the spatial pattern of tectonic hazards and their causes in contrasting tectonic locations.
For question 1, you would probably need to go into some detail about continental and oceanic plates and how they move (by convection currents in the core). You should consider the following types of plate boundary: 1. Destructive boundaries These are sub-divided into: -Oceanic-continental boundaries -Continental-continental boundaries (collision zones) -Oceanic-oceanic boundaries 2. Constructive boundaries 3. Conservative/transform boundaries You should research what happens at each type of boundary, the resulting tectonic hazards and any landforms that are produced. Remember that different plate boundaries vary considerably - some produce very violent earthquakes and explosive volcanic activity whereas others produce gentle eruptions and earthquakes. I would also note down some named examples of each type of boundary and perhaps case studies of earthquakes and volcanic eruptions that were caused by a specific boundary. For question 2, it seems to me that they might be looking for some human factors to be mentioned, i.e. factors that make one particular tectonic hazard much more severe than others. For example: degree of preparation, population density, distance from epicentre, secondary impacts (e.g. tsunami, fire), magnitude of earthquake etc

Examine the Physical Processes That Cause Tectonic Hazards Including Plate Boundaries and Other Factors

...Examine the physical processes that cause tectonic hazards including plate boundaries and other factors A range of case studies, scales and locations will be used to investigate physical causes of tectonic hazards. ’A natural hazard would be defined as a natural event that has the potential to threaten people’s lives and property’ Whittow 1980. Therefore, we could define a tectonic hazard as a geophysical process involving seismic activity and the movement of the earth’s plates, creating events such as earthquakes, tsunamis and volcanic eruptions. Physical processes that cause tectonic hazards including plate boundaries and other factors can be separated into 2 categories; these are primary and secondary hazards. A primary hazard is a hazard that came as a direct result of the tectonic activity, whereas a secondary hazard is a hazard which is created by primary hazards, these include tsunamis, lahars and aftershocks. The physical processes that cause tectonic hazards occur at plate boundaries. These plate boundaries are categories as: convergent (oceanic- continental), convergent (continental- continental), divergent (oceanic- oceanic), divergent (continental- continental), transform and collision zone. However these tectonic hazards do occur elsewhere as a result of intra-plate boundaries and hotspots. Other physical factors that cause tectonic hazards include relief of land, geology and aftershocks. Tectonic hazards revolve around the key idea of tectonic theory put......

Earthquakes and Other Tectonic Disturbances Pose One of the Major Physical Threats to Civilisations Particularly in Developing Countries

...Earthquakes and Other Tectonic Disturbances Pose One of the Major Physical Threats to Civilisations Particularly in Developing Countries The major factors to this will be looking at tectonic activity, the earthquakes they cause aswell as the distribution of these developing civilisations in order to ascertain whether the major threat to their final goal of civilisation is plausible or not. Earthquakes are defined in the Oxford dictionary as: a sudden release of energy in the earth's crust or upper mantle; usually caused by movement along a fault plane or by volcanic activity and resulting in the generation of seismic waves which can be destructive. Tectonic plates are defined as: A theory explaining the structure of the earth’s crust and many associated phenomena as resulting from the interaction of rigid lithospheric plates which move slowly over the underlying mantle; by the same dictionary. Finally, civilisations are defined as: The process by which a society or place reaches an advanced stage of social development and organization. The largest cities tend to be in developing countries due to the fact they have not yet reached stage 5 of the Demographic Transition Model and many of the pull factors that cause cities to grow still exist. MEDC’s tend to have reached a point whereby people move out of major cities in order to find a suitable environment for family life. Thus from this we can see that already LEDC’s are most at risk from tectonic activity. Earthquakes......

Analyse the Factors That Causes Differences in the Hazards Posed by Volcanoes Around the World (40 Marks)

...Analyse the factors that causes differences in the hazards posed by volcanoes around the world (40 marks) A hazard can be define as something which poses a level of threat the life, health, property or environment, a volcano can compromise all these things through the many hazards volcanoes presents. Such as lahars, flash flooding, landslides, pyroclastic flows, ash clouds and many others. There are factors which can influence the severity of the hazard and cause differences in them and can be classified into different categories, such as physical, economic, political and social. One physical factor which causes differences in a volcanic hazard is the steepness of the volcano. If the volcanoes sides are of a steep gradient then the lava from the volcano would flow must faster than if the sides were a steady gradient. Mount Nyiragongo for example had extremely steep sides, 50 degrees at some points. This, combined with the low viscosity of the basaltic lava, saw lava speeds of up to 60 miles per hour. The hazard of a lava flow in Nyiragongo was much greater than if the volcano had steady sloping sides. The type of lava also influences the hazard, if the lava is ryolytic then it has a high viscosity due to its high silica content and its low temperature (only between 650-750 Celsius). Therefore it won’t flow very fast, minimising the impact of the hazard, whereas if it is basaltic like Mount Nyiragongo then it will flow extremely fast, intensifying the hazard. The......

Plate Tectonics and Earthquake Hazards in Los Angeles

...GLG/200 Allen Fronabarger PLATE TECTONICS AND EARTHQUAKE HAZARDS IN LOS ANGELES There are many serious hazards associated with earthquakes in the Los Angeles metropolitan area. This includes ground shaking, ground displacement, liquefaction, fires, and tsunamis (Girty, 2009, Chapter 7). During an earthquake there are varying degrees of vibration of the ground, dependent on the magnitude of the earthquake. This violent movement of the soil can compromise the structure of buildings or other structures made by man, causing them to crumble to the ground and crushing anything, or anyone, that may be in close proximity. If some sort of structure, made by man or by nature, happens to lie upon a fault line, the ground displacement of the foundation of the structure can also cause immense damage by ripping apart the land. In some instances, where soil is highly saturated, such as coastal areas or low elevation, liquefaction is another hazard. When the ground shakes, any present liquid will rise up through the soil and make sinkhole conditions where structures can sink right into the ground. With this kind of destruction, comes the hazard of fires as well. During a violent earthquake, electrical and gas lines can be destroyed and exposed to ignition sources that can ignite and cause fires that may be inaccessible and be extremely destructive. Lastly, tsunamis are a risk to L.A. when there are quakes offshore that launch large quantities of sea water over the coastal......

Tectonic Hazards

...Option 1 – Tectonic Activity and Hazards What are tectonic hazards and what causes them? 1. Introduction Tectonic hazards have to be distinguished from tectonic events. Hazards tend to refer to those events or items that pose a threat to humans and their lifestyle. Therefore, a tectonic hazard is one which involves tectonic processes being hazardous to humans. In the first part of my essay I will be explaining exactly what is meant by tectonic processes and will be referring to the relatively new concept of Plate Tectonics which, although being presented as a theory in 1912 by Alfred Wegener, was not actually taken as the standard model until the late 1960’s and even then was being criticized by many learned scholars into the 1980’s. I will then explain what the main types of hazards are in tectonics, namely volcanoes (openings in the earth crust from which material from below the earth’s surface can be ejected) and earthquakes (movement in the earth’s crust that causes shaking of the ground above). However, there are many more hazards that can be associated with these two, namely tsunamis and from volcanoes, pyroclastic flows, lahars and volcanic gases. What causes these hazards should be explained in my explanation of plate tectonics. Throughout my assignment, I will be using many examples of tectonic hazards from around the globe, but will be focusing on certain case studies to try and explain exactly what causes tectonic hazards. I will be using the San Andreas......

Analyse the Factors That Cause Differences in the Hazards Posed by Volcanoes Around the World.

...Hazards will be an unfortunate result of a volcano. They are defined by their ability to effect any property and life that can be lost due to the hazard and halts and slows the productive sustainability of a population. Ultimately the physical effects of a volcano will define the hazards. In different places that the volcanoes occur there are different plate margins (Destructive and constructive) that will create different types of hazards. These hazards will include; lava flows, mudflows, pyroclastic flows, ash clouds etc. The majority of the hazards that occur are posed by physical reasons. The underlying reason that the hazards occur is due to the plate margins. The first type of plate margin is Constructive. Constructive plate margins will create a volcano due to the plates moving apart form each other. Due to the immense pressure on the plates, it causes the mantle to melt, producing magma. This magma will rise due to its density and erupts as a volcano. An example of a volcano of this nature is in Iceland. Eyjafjallajökull is situated on the island of Iceland classified as an MEDC and has a population of 300,000. Iceland has been prone to volcanic eruptions for centuries, however in 2010 it erupted on a global scale. The main hazard that occurred from the eruption was Joküllhaup. This occurred due to the sublimation of glacial ice mixing with ash, to produce fine glassy ash particles. This was a major set back to the world’s airspace as the ash had entered the......

The Extent to Which Tectonic Processes Represent a Hazard Depends Upon When and Where They Are Experienced

...A hazard can best be defined as a 'situation that poses a level of threat to life, health, property or the environment'. The overall impact of earthquakes as a natural hazard varies greatly from one place and time of day or year to another. As do the types of hazards, which are classed as either primary or secondary hazards. Primary hazards are created by the direct seismic shaking of an earthquake; this could include liquefaction, slope slipping and tsunamis. These primary hazards can in turn trigger secondary hazards such as floods, fires, disease and damage to infrastructure making them less stable. A number of factors play a part in determining the severity of these hazards. For me the most influential factor is where the tectonic process occurs in relation to the levels of development of that area. HIC's tend to cope better with the hazard of earthquakes and volcanic eruptions than LIC's because they have all the necessary resources to survive the effects of these hazards at their disposal. Such as earthquake proof buildings that are designed to withstand earthquakes by using strong materials such as reinforced concrete or building special foundations that absorb an earthquakes energy e.g. the Bank Tower in Los Angeles, California. Construction laws in some earthquake-prone countries (e.g. Japan, the US and China) have become stricter in recent years – this means that newer buildings are more likely to be able to withstand earthquakes. This is most apparent in Sichuan......

There are factors which can influence the severity of the hazard and cause differences in them and can be classified into different categories, such as physical, economic, political and social. One physical factor which causes differences in a volcanic hazard is the steepness of the volcano. If the volcanoes sides are of a steep gradient then the lava from the volcano would flow must faster than if the sides were a steady gradient. Mount Nyiragongo for example had extremely steep sides, 50 degrees at some points. This, combined with the low viscosity of the basaltic lava, saw lava speeds of up to 60 miles per hour. The hazard of a lava flow in Nyiragongo was much greater than if the volcano had steady sloping sides. The type of lava also influences the hazard, if the lava is rhyolitic then it has a high viscosity due to its high silica content and its low temperature (only between 650-750 Celsius). Therefore it won’t flow very fast, minimising the impact of the hazard, whereas if it is basaltic like Mount Nyiragongo then it will flow extremely fast, intensifying the hazard. The location of a volcano is also a large variable in determining the nature of its eruptions. Volcanoes are......

Tectonic Hazards

...With reference to particular examples, suggest why the impacts of tectonic hazards vary from place to place Tectonic hazards are natural events occurring due to movements or deformations of the earth’s crust with the potential to cause damage to lives and properties. E.g. earthquake and volcanic activities. The impact caused by tectonic hazards on lives and properties are mainly determined by physical factors, vulnerability factors and affected region’s capacity to cope. These factors are parts of the risk equation, which is used to measure the level of hazard risk of an area. Which I will be using it to explain why the impacts of tectonic hazards vary from place to place. One of the main reason why some place suffers more than the others is the global distribution of earthquakes, this is due to the margins of tectonic plates. It is commonly known that earthquakes happen on the plate boundaries. However, at some plate margins, earthquakes are more destructive and frequents, for example, Eurasian plate and Pacific plate, where Pacific plate sinks under the Eurasian plate. The impacts of tectonic hazards seem to vary significantly in countries with different economic development. This is evident in 2010, with an earthquake reached magnitude of 7.1 on the Richter scale, struck Port-au-Prince, the capital of Haiti, with 316000 people being killed. Whereas in 2011, an earthquake reached magnitude of 9.0 on the Richter scale struck Japan caused just 20896 deaths. The......

Hazards

...“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.......

The overall impact of earthquakes as a natural hazard varies greatly from one place and timeframe to another. As do the types of hazards, which are categorised into primary and secondary.

Analyse the Factors That Cause Differences in the Hazards Posed by Volcanoes Around the World.

...Analyse the factors that cause differences in the hazards posed by volcanoes around the world. Volcanoes and their hazards have posed many problems across the world since they were formed. Due to their often aggressive activity they have been damaging to variations of human life. However these hazards are different depending on many factors, such as the nature of the hazard, the area where these hazards occur and the level of preparedness that area has. In this essay these factors will be studied to see if the effect of these volcanic hazards varies around the world. When a volcanic event occurs there are many hazards that could come from it. The primary being tephra; which is solid material varying in size that is ejected into the atmosphere, pyroclastic flows; which are very hot high-velocity flows, volcanic gases including carbon dioxide, carbon monoxide and lava flows. The secondary being lahars; which are volcanic mud flows, flooding through melting of ice caps, tsunamis from giant caldera forming events, volcanic landslides and climate change due to the ejection of vast amounts of volcanic debris into the atmosphere that can reduce global temperatures. These hazards have caused incidents such as when lahars devastated the Colombian town of Armero after the eruption of Nevado Del Ruiz in November 1985. From this we can deduce the high level destruction that these hazards can cause. Two volcanic events where the hazards have affected the area around them are......

Analyse the Factors That Cause Differences in the Hazards Posed by Volcanoes Around the World (40)

...volcanoes erupt globally. A hazard is a naturally occurring event that has the potential to cause loss of life or economical damage. The hazards that are caused by Volcanoes can vary in size and depends on the scale of the eruption; if it is a small eruption then it has minimal impacts, whereas a larger eruption can cause mass disruption. There are many factors both human and physical that affect how hazardous a volcanic eruption may be. One physical factor that affects how hazardous a volcano can be is the type of volcano. Composite volcanoes are formed by alternating layers of ash and rock and rock fragments unlike shield volcanoes, can be extremely dangerous. This is because of their sheer size, height and steep sides; they often form ice caps and glaciers at the peak, which melt due to the heat. When the water runs down the volcano, it mixes with other materials such as mud and rock, causing lahars. Lahars can rush down streams and valleys at high speeds and can travel distances of over 50 miles; they can carry or destroy most things in their way including houses and trees. When they get further downstream, they start to move slower and eventually end up covering everything in a thick layer of mud. This can be one of the most deadly hazards, as it destroys houses and can leave people homeless, when Pinatubo erupted it destroyed 42,00 homes and left 1.2 million people homeless. The eruption of Nevado Del Ruiz, in Columbia demonstrates the hazards associated with lahars......
