Managing the earthquake hazard Homework 07/03/15 Mitigation: Modify the event 1. How realistic is the control of the physical earthquake event? Control of the earthquake event itself and physical variables such as the location of the epicentre‚ depth of the focus‚ foundation material ie rock type‚ duration of shaking and time of day is not a realistic form of management. Earthquakes caused by humans on the other hand such as those resulting from dam destruction can be managed by considering

Earthquakes in GCC An Earthquake known also as tremor is resulted from a sudden release of energy ‚which takes place in the earths crust‚ which then creates seismic waves. They are vibrations triggered by movement of rocks that have been strained (deformed) beyond their elastic limit. This activity called seismicity or seismism of an area refers to type ‚ size and frequency over a time period. Earthquakes are measured using many instruments ( up to atleast 20 different types

With reference to waste management‚ discuss the extent to which sustainability can be achieved. (40 marks) Waste management is all about the need to change our attitude to waste. The four methods of managing waste at the moment are: landfill‚ composting‚ recycling and energy recovery (incineration). To be sustainable‚ waste must be managed in a way that is maintainable for the foreseeable future and will not be hurtful to the environment or the population. Waste is a problem at the moment because

To what extent can preparedness and planning mitigate the effects of a volcanic hazard (40 marks) Volcanic activity happens across the surface of the globe therefore bringing hazards to every affected area. A hazard is any source of potential damage‚ harm or adverse health effects. A volcanic hazard is any threat to life and infrastructure due to volcanic activity and related situations such as a landslide near the volcano. Volcanoes can be very dangerous and therefore present many hazards towards

To what extent can preparedness and planning mitigate the effects of volcanic hazards? (40 marks) Volcanic activity happens across the surface of the globe and naturally hazards occur too. A hazard is a situation that poses a level of threat to life‚ health‚ property‚ or environment. It is easy to locate volcanoes‚ but it is very difficult to predict exactly when activity will take place‚ particularly a major eruption‚ this makes it difficult to prepare or plan for one. There is a very big difference

To what extent can preparedness and planning mitigate the effects of Volcanic Hazards (40 marks) More than 500 Million people live within 50 miles of a volcano‚ the potential therefore exists for major loss of life and damage to property and infrastructure‚ particularly when urban areas are situated in close proximity. Mitigation of such losses can be achieved through careful preparedness and planning. Preparedness is the process of ensuring that an organization has complied with the preventive

of bi-articulated bus. These buses travel along designated routes carrying over 10000 passengers per day each. The Rapid Bus Network as it is known has been calculated to be 500 times cheaper than a subway system. Unlike a subway system the network can increase the number of buses in response to varying demand. The Curitiba RBN operates cost effectively‚ making it extremely economically sustainable. London is also a financial hub. Unlike Curitiba it has adopted an underground train system. The system

To what extent can organisational culture be managed? Is organisational culture critical to the success of an organisation? Peter Anthony (1994) asserts that the pursuit of change in a cultural sense has been considered synonymous with the pursuit of excellence for organisations. It is true that a wide variety of management practitioners view the control of organisational culture as something both possible and necessary for organisational success (Brown 1993). A survey of organisational practices

Volcanic hazard depend primarily on physical factors? Discuss. Volcanic eruptions happen all across the surface of the globe‚ many argue that if controlled and monitored they would have little effect on the population. However others argue that some volcanic events are too powerful or unpredictable to control. Firstly I do not agree with this view I believe it is more to do with the human decisions that make a volcanic eruption a hazard. For example we can see this in such volcanic events such

To what extent can preparedness and planning mitigate the effects of volcanic hazards? (40 marks) A hazard is a situation that poses a level of threat to life‚ health‚ property‚ or the environment. Therefore‚ in this case a volcanic hazard is the threat posed from natural volcanic processes towards the populations and the environment. The extent of volcanic hazards can vary due to two factors; physical factors such as the type of volcano and human factors such as the population density in the area
