´╗┐Geography Essays (a) Suggest why some places are more at risk of than others of experiencing a major volcanic disaster? There are a number of reasons why some places are more at risk of experiencing a major volcanic disaster. One reason is their geographical position within the world and in relation to tectonic plate boundaries. For example you have highly destructive and explosive volcanoes often found along destructive plate boundaries because of increased pressure within the subduction zone. An example of this is the Philippines, which is situated above a destructive plate boundary and this leads to numerous and highly destructive volcanic eruptions. You also find volcanoes along constructive plate boundaries where the plates are moving apart and this is creating new lands and volcanoes as molten lava builds up, an example of this is the Mid-Atlantic ridge which Iceland sits near. Figure 7 also shows us that there is a high level of volcanic activity within the pacific ring of fire, this is because of the high amount of destructive and constructive plate boundaries within this area and this causes major volcanic disasters. ...read more.


To conclude some places are more prone to major volcanic disasters for a number of reasons from physical aspects like their geographical position to human aspects such as population density around volcanoes and prediction and planning procedure. (b) Explain why the Philippines and California multiple hazard spots are affected by disasters in different ways? The Philippines is a cluster of many islands and they suffer from many hazards within the area. The Philippines situated upon an active destructive plate boundary and this means that they have many highly active and highly explosive volcanoes on these islands (17). As it is on a destructive plate boundary there are also a high number of destructive earthquakes (65 in 400 years) because of the high pressure within the subduction zone. The Philippines also experiences many tropical storms due to its latitude and on average experiences from 4-12 per year with an average death toll of 529 people and an average cost of 90 million US dollars. ...read more.


emissions in a pollution plume and this can lead to serious health problems such as asthma and respiratory problems in the future. The two areas are vastly different with the Philippines being a R.I.C (rapidly industrializing country) with a low income and where poverty is a major factor and this can be hugely detrimental to the country as it tries to cope with disasters and it also increases the vulnerability of the people living there. Compare this to California which is a very rich region with a population just over 37 million and because of this it can cope very well as it can implement the 3p?s: Preparation, Planning and protection. This means that despite its high vulnerability to disasters it can cope very well with them with little loss of life, but still high economy losses. This is different to the situation in the Philippines as because of its poverty it struggles to plan and prepare for hazards and is ill equipped to cope with high fatalities and huge economy losses for its people in proportion to their actual wealth. ...read more.

    Explain the increasing frequency of Hydro-meteorological Hazards.

    3 star(s)

    It is suggested that, some hydro-meteorological hazards, such as floods and windstorms are increasing in frequency, due to global warming. The idea behind this is that the increasing warming of the earth causes warm air to rise, creating convection currents and then hurricanes.

  2. Earthquakes are perhaps one of natures most breathtaking, yet deadly and destructive wonders.

    The Nikkei index lost 5.6% of its value as a direct consequence and many trillion Yen was needed to repair the infrastructure. Estimates on how much the damage cost to repair ranged from $95 billion and $147 billion not including lost revenue.

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

    Both California and the Philippines lie on plate boundaries and therefore both suffer from severe tectonic hazards. The Philippines lies on the subduction zone of a destructive boundary between the Eurasian and Philippines plate, and therefore is high-risk area for both earthquakes and volcanoes.

  2. Mount St. Helens - Natural disasters.

    Then a lighter ash fell, made mainly of pumice. Enough trees to build 300,000 houses where knocked down by the blast. Huge amounts of wildlife where all killed as well, The Washington State Department of Game estimated that 5,000 black-tailed deer, 1,500 Roosevelt elk, 200 black bears, and 15

    Drought, caused by El Nino events effect those that are poorer because they rely on their crops and agriculture to make a living. Drought means that their crops die and therefore they will not be able to make an income and support their families.

  2. Earthquakes: Why do some places suffer more than others?

    subducting plate descends at a slight angle, thereby creating stresses close to the surface. Where the depth of an earthquake is deeper, typically the impact is less destructive. Indeed larger magnitude quakes, with deeper focuses often incorporate less damage than shallower quakes with larger magnitudes.

  1. California and the Phillippines - Hazard Hotspots and Human Management of Risks

    * Base Isolation: This is when structures are built such that during an earthquake the base of the building moves with the ground however the building itself does not move. As a result it does not lead to structural failure.

  2. Volcanic and seismic events are major pieces of evidence towards proving that plate-tectonics theory ...

    If the ocean basins were as old as the continents, we would expect deep-sea sediments to be several kilometers thick. However, data from numerous drill holes indicate that deep-sea sediments are at most only a few hundred meters thick and are thin or absent at oceanic ridges.
