The relevance of time and place can play a huge role in the levels of dangers and consequences that occur when related to a volcanic eruption. Within this essay I will consider all the contributing factors that can influence the processes that take place. Comparison between different volcanoes with specific differences, both in LEDCs and MEDCs, will provide a vivid and comprehensive representation of the variations involved in volcanic processes. A hazard can best be defined as a "situation that poses a level of threat to life, health, property, or the environment." The overall impact of volcanoes as a natural hazard varies greatly from one place and time period to another. The same applies to the type of risks, which are classified into primary and secondary. Primary hazards, created by the volcano's direct eruptive energy, could include pyroclastic flows, ash clouds and large volcanic bombs. These primary risks can in turn trigger secondary risks such as floods, fires, disease and infrastructure destabilization. Another factor that could suggest the severity of the hazard is the differentiation between the volcanic landforms involved. These reflect the nature of the material involved, the nature of the eruption and the time since the last activity. Perhaps the eruption was basaltic, originating largely from the upward movement of mantle material. They are most common along extended ridges, but are also found in hotspots and within more developed rift systems. These types of volcanic eruptions are basic level. Lava here would not be at the higher end of the risk scale as it spreads slowly and smoothly as the liquid has a liquid form. However, if the eruption were classified as andesitic it would be marginal... middle of paper... you on the volcano for twenty years with a well-known network of remote sensors, radios and telephones at the center in Catania. Communication in this area is vital and is their main ingredient in decreasing death, disease and destruction. In conclusion, I believe that preparation and awareness of what is about to happen, regarding a volcanic eruption, is the key to a less unfortunate life. event. Monitoring systems and forecasts are vital to limit the amount of deaths and the infrastructure of buildings and land. Usually this only applies to MEDCs and using my knowledge and research that I have highlighted in the chosen case studies. However, volcanic processes will continually affect people around the world. Wealth and organization will reduce the representation of risks typical of more economically developed countries.
