Extracts from this document...


Natural hazards are caused by the interaction of physical and human processes, discuss. The earth has been producing hazards for millennia these include earthquakes and volcanoes caused by the movement of tectonic plates, and also wind and water elated disasters such as tornadoes and tsunamis, these can be varied by a countries location such as suffering drought due to be land locked or an island, also the relief on the land can contribute greatly to the hazards it faces.. All of these cause great destruction and can involves lots of energy, these events do not become disasters unless there are human factors involved, when people live on a fault line they are risking suffering from an earthquake, this combination of physical and human processes can lead to large losses not only in lives but also monetary due to lost land, employment and homes. The problems associated with a hazard may be short lived on continue for decades, drought can effect a region for over 5 years, ...read more.


LEDCs, thus evacuation and warning is not available, this can be seen in the Grecian city of Pompeii which was engulfed by a volcano with very little warning the result being the loss of almost all of the city and its inhabitants. Some natural hazards can be effected by the actions of humans, the deforestation of forests in Indonesia is suspected to have contributed to the mudslides their, the resulting loss of life could be blamed on illegal logging which had occurred. The flood risk of countries is also increased by the urbanisation of land, the concrete and other impermeable surfaces used mean that water reaches rivers faster which can cause the river to burst it's banks, this occurred in Berkshire and other urban areas by the M4 which closely follows the route of the river Thames and its tributaries, this had flooded many time in recent years and the problem in acerbated by the increased urbanisation of the land. ...read more.


These combined with earthquakes can cause mass movement of the land; this can result in further human related complications as fires are started by broken gas mains. Also when land is built on reclaimed land such as sand reclamation on the west coast of America, an earthquake could cause liquefaction to occur turning the once stable base of people's homes into a river of mud and sand. Very few of these events would become a hazard unless humans were either living their or has contributed to the actual problem, land which has no population frequently shows no ill effects of these natural processes and in some it has positive effects, when Egypt was only populated by very few the yearly flooding of the Nile ensured that the farm land was irrigated and also had fresh nutrient, now the dam means this no longer occurs and if the dam breaks a huge flood killing millions could result.

    Radon gas is measured as it will be released more quickly from granite and similar rocks when they are deformed by shifting. Ground water may rise independently of atmospheric conditions. Protection methods include; making buildings earthquake resistant; educating the public about disaster prevention; improving earthquake predication; implementing better evacuation plans and reducing the risk of fire.

    Therefore, it is possible to conclude that America's knowledge of physical processes was vital in the understanding of the occurrence of the event, especially when compared with another hurricane, Hurricane Mitch, which struck Honduras in October 1998. Since Honduras is an LEDC, it does not have the satellite technology that America does to track hurricanes like Mitch.

  1. Write an account of the relationship between tectonic processes and global structures

    The movement of the continental plates is due to the up welling limbs of convection currents deep within the mantle. Heat energy rises from the hot core and spreads sideways below the crust, moving the continental plates sideways. New oceanic crust must be created to fill the gap left by the retreating continents.

  2. What is an environmental (natural) hazard?

    ProVention is a coalition with Governments to help people take charge in identifying and reducing the risks they face. They are working towards a more complete understanding of the full economic, financial and social impacts on a country. ProVention functions as a network to share knowledge, connect resources and reduce disaster risks.

    This type of damage reflects the economic development in each country (the USA is able to afford main roads and telephone cables whereas Bangladesh cannot) and it meant the damages cost was much higher in the USA. These facts and figures suggest the impact was worse in Camille than Bangladesh, but everything is relative.

    Slopes will become weaker quicker. Triggers of mass movement can also be both physical and human. * PHYSICAL - Earthquakes, volcanoes, heavy rain, snow melt, gravity * HUMAN - Modification of land, (e.g. urbanisation, building) mining, machinery use, deforestation, extraction of resources Physical factors Causes of mass movement - The

  1. Discuss how far tectonic hazards can be viewed as purely physical processes

    Over long periods of time the plates also change in size. Different types of plate boundary (e.g. oceanic v continental) and different plate motions (e.g. destructive, constructive and conservative) generate different types of hazard. The most explosive volcanic activity and the worst earthquakes occur on destructive boundaries (involve large energy

    This produces a disaster. There have always been definitions attempting to describe what "disaster losses" were. In 1969, Sheenan and Hewitt defined it to have satisfied one or more of the criteria in Table 1: 1969: Swiss and Hewitt Definition 1990: Swiss Reinsurance Company Definition At least US$1 000 000
