Mass movements, the downhill transfer of slope material as a coherent body, are often caused by the interaction of both human and physical factors. In Armero two rivers coming down from the volcano surrounded the worst affected town the town.
The techniques available for predicting and monitoring volcanic activity are becoming increasingly accurate. Harmonic tremors are often the result of magma pushing against the overlying rock below the surface.
However, in the aftermath of the storm, the U. Most volcanic gases are noxious and smell bad, but they can cause mass fatalities. Furthermore, despite planning and preparation, if the scale and size of an event is large enough, it is evident that the most prepared and resistant societies cannot even cope.
Mount St Helens showed this prior to its eruption in Vulnerability is one of the main problems when it comes to mitigating and preparing for disasters. This will be done by exploring how preparation and planning can help, then by evaluating how they reduce different impacts, and finally by seeing what other factors influence the effects of volcanic hazards e.
But other physical factors can have very different effects. In the area of Sichuan, seismic building codes and not be obeyed and buildings were poorly constructed resulting in overdeaths in when the earthquake hit the region.
I will also look at the effects of volcanic hazards spatially, on both global and local scales, and temporally. Additionally, it was due to effective planning in the densely populated LA Metropolitan region of California prior to the Northridge Earthquake which prevented the death toll exceeding This means that due to the short warning time, it is very difficult for an area to mitigate the effects of a volcanic hazard as there may not be enough time to plan and prepare for the impacts of an eruption therefore maximising the hazards posed by this type of eruption.
A prediction based on the statistics of previous eruptions is too vague for specific and short -term prediction of an eruption. I will show how the extent depends on the type of hazards, frequency and geographical e. Theses events are often extremely quick onset and therefore difficult to prepare and plan for.
Many volcanoes experience an increasing intensity in frequency and size of earthquakes as they prepare to erupt. Any small scale activity continued for months and therefore people disregarded any advice including evacuation methods as they thought it was not posing any major threats.
I will also take into consideration how other factors can influence the effectiveness of preparations and plans, such as the size of the volcano, its location, the demographic of the area, and the development of the country.
It must also be noted that although preparation and planning can reduce the humanitarian effects, the economic impacts are another story. Using these I will evaluate the preparedness of the communities affected by the eruption and the effects of the hazards to ultimately come to a conclusion.
Also, ground deformation involves the movement of magma within the lithosphere can deform the ground above, this has been witnessed at Yellowstone beneath Yellowstone Lake. Through ought this piece i will be discussing to what extent preparation and planning can help to mitigate the affects of volcanic eruptions both on a local and international scale.
This meant when the lahar formed it flowed down these rivers faster and stronger then it would have done land. However, success is dependent on a number of factors including vulnerability, exposure, the size and scale of the hazard, and the amount of money available.
However, measures can be taken to ensure slope stability and dynamic equilibrium to oppose the resisting downward forces to help prevent such an event.
This is useful for monitoring any changes in volcanoes at the surface. Preparedness and planning in the case of volcanoes can involve prediction as quite often through monitoring seismicity, Bernard Chouet ground inflation, and fumarolic behaviour a volcanic eruption, to a certain extent, can be predicted.
Social death and injuries for exampleEconomic such as loss of jobsand Environmental this could be something like air pollution. These factors are mainly controlled by spatial and temporal effects resulting in different methods such as evacuation not being as effective in certain areas.
I will evaluate how different planning and preparation methods can reduce these effects, using case studies as examples.
On rare occasions, powerful explosions spread ejecta across the landscape. Breaking the headings down to cover a range of sub topics such as effects on tourism, the atmosphere and infrastructure.
Despite only 57 deaths in California inthe Northridge quake was the most economically devastating and the Pakistan floods of summer destroyed This means that they have a large variety of data on past lava flow so they can predict patterns and theories of where the lava will most likely flow.
With pyroclastics you can only reduce the hazard by vacation but lava flows can be diverted and slowed down with dam wall trenches and spraying water As they did in ice land on the Heimaey eruption which started on 23 January.To what extent can planning and preparedness mitigate the effects of seismic hazards?
Can planning and preparedness reduce the effects experienced due to earthquakes? To what extent can preparedness and planning mitigate the effects of tropical revolving storms?
 Tropical revolving storms are also known as hurricanes, typhoons and cyclones. They occur in the tropics and sub-tropics and form over the oceans where sea surface temperatures are above 27 degrees C.
1 9 ‘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 environment - 1 9 ‘To what extent can preparedness and planning mitigate the effects of volcanic hazards?’(40 marks) introduction.
In this essay i will be evaluating to what extent prepardness and planning can mitigate the effects of volcanic hazards such as ash clouds, pyroclastic flow, lava flows, lahars and tephra.
I will be exploring the economic and social impacts in sutuiatuions such as Eyjafjallajökull and nevado del ruiz. 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. Apr 29, · To what extent can preparedness and disaster planning mitigate the effects of earth hazards? Whittow in defines a hazard as a “perceived natural event which has the potential to threaten both life and property, and a disaster is .Download
