The Human Impacts of Tectonic Landforms & Hazards

Extracts from this document...


´╗┐Human impacts of tectonic activity Why live in tectonically active areas? Lack of knowledge: Even today there are people who do not understand why or where tectonic activity takes place. Tectonic activity does not only take place at plate boundaries ? intra-plate earthquakes, e.g. Bam, Iran. This leads people to think it won?t happen to them. The developing world has fewer resources or expertise to study the natural environment (or human environment) ? methods to identify areas at risk may not exist (e.g. poorer levels of education), especially if the area is not very active. Pompeii ? a classic case of ignorance to disaster. The lack of an eruption in ?living memory? led many to believe that Vesuvius was dormant. In 79AD there was no expectation of an eruption ? people were caught completely unaware. ...read more.


Impacts on people and possessions: The severity of the impacts depends on physical factors (e.g. event profiles, geology, terrain) and human factors (e.g. population density). Physical impacts on people: Damage/destruction of property and infrastructure. Volcanoes – luckily ¾ of erupted lava is from underwater volcanoes, much of it along ocean ridges, so the impact is minor. The greatest risk is at destructive plate margins. Most active volcanoes are found in the developing world, e.g. Latin america, the Caribbean, parts of Asia and the south-west Pacific. Increased urbanisation and population growth concentrates people and infrastructure. Earthquakes – the worst earthquakes are not necessarily those with the largest magnitude. The worst impacts are felt in densely populated areas and areas with high vulnerability. Economic impacts on people: These can be direct or indirect. ...read more.


Usually greater in developing countries than developed. Secondary casualties ? those that survive the event itself but die/are injured due to insufficient resources or lack of medical care. Again, usually greater in developing countries than developed. Tertiary casualties ? those with pre-existing medical conditions that are aggravated by the event. Includes those who become ill/die. For example, through disease contracted in the post-disaster environment. In developing countries, these are often the largest group of casualties. Poverty reduces the capacity to reduce the impacts, or to recover. Environmental degradation reduces natural impact buffers, e.g. mangrove removal (Indian Ocean, 2004), and therefore contributes to delaying recovery time. Note: to more accurately compare the impacts in developed and developing countries, it is better to use damage cost as a % of GDP, as developed countries have more infrastructure, etc., to be damaged. The absolute costs may be lower in a developing country, but the relative costs (as a % of GDP) are likely to be much higher. ...read more.

    kms. of volcanic material. The ash cloud from this huge eruption rose 22 miles (35 kms.) into the air. A blanket of volcanic ash and larger pumice pebbles blanketed the countryside. Fine ash fell as far away as the Indian Ocean, and satellites tracked the ash cloud several times around the globe.

  2. Suggest why droughts have severe impacts on people and the environment.

    The increased desertification has major damage on the many different animal species, livestock numbers will decrease due to the decrease in water available and the increase in water cost, so their owners cannot afford to provide them with water. Other animals, living in the wild will die, also due to

  1. Mount St. Helens - Natural disasters.

    Seismometers recorded 37 earthquakes larger than magnitude 3.0, including 6 larger than magnitude 4.0. A new tiltmeter at Timberline began sending continuous data to Vancouver. The USFS officially designated Mount St. Helens a "geologic area," which protected the forest around the mountain from future land use changes.

  2. Compare and contrast the Philippines and Californian hotspots, giving an opinion as to which ...

    La Nina oscillations means that California receives dry winds from the Arizona and Mexican deserts causing dry, hot weather often resulting in drought and increased wildfires. For the Philippines this is the other way round although, being in a tropical zone, wet monsoon seasons and dry seasons are experienced annually anyway.

  1. With reference to a range of hazards, assess the success of prediction techniques in ...

    Unfortunately LEDCs such as Monsterrat cannot afford scientists to predict when volcanoes will occur and therefore when the volcanoes do erupt the areas is often unprepared. With many volcanoes erupting only every few hundred or thousand years, it's not possible to monitor every site.

  2. Compare the physical causes of tectonic hazards at contrasting plate boundaries

    Atlantic Ridge which is located on the floor of the Atlantic Ocean, and is part of the longest mountain range in the world. The MAR is mostly underwater however the island of Iceland is above the water and sits on top of a hotspot meaning that it is very volcanic, and has eruptions roughly ever 5-10years.

  1. Discuss the view that the impacts of volcanic hazards depends primarily on human factors

    Therefore this damage was not due to human factors. There was also the landslide that occurred on the north side of the volcano. This was one of the largest landslides in history and covered 24 square miles.

  2. The World Distribution of Population is as important as the world distribution of areas ...

    mismanagement; and a lack of regulatory mechanisms both increase the risk and exacerbate the effects of disasters," which clearly illustrates the relationship between volcanic disasters, populations, planning and development; demonstrating the vital influence of population change in risk reduction. Furthermore, humans being the victims of the greatest hazard is emphatic
