The Extent To Which Volcanic Processes Represent Hazards Depends On Where And When They Occur

The extent to which volcanic processes represent hazards depends on where and when they occur
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 depending on the time and place. Different plate margins known as constructive and destructive on volcanic eruptions and landforms have different effects for example. Volcanic activity that occurs at a destructive plate margins such as in Mount Merapi & Mount St. Helens eruption potentially could be an explosive volcanoes which are hazardous but even then both of these volcanoes can be effected differently still.

To begin with, an example of a more economically developed country where recent volcanic eruptions have occurred is Sicily, where Mount Etna regularly erupts. These eruptions are overall handled relatively effectively by the local government to reduce the overall destruction done to surrounding settlements through the use of monitoring the volcano for evidence or early signs of eruption which helps them evaluate the best way to deal with the volcano and arrange evacuations. Due to economic development they are also able to have permanent measures in place in order to drive the lava flow away from areas of settlement.
On the other hand, there are examples of a less economically developed country that has had a recent eruption is Montserrat, where the volcanic eruption had a far greater effect than the eruptions of Mount Etna in Sicily. Because of less economic funding in the area There was little in the way of prevention of destruction in Montserrat and the only significant response was that of an evacuation order and no access zones of the country set up in the years prior to the eruption that some people neglected and were eventually killed by the large eruption. The differences in the levels of destruction that these two cases had could be due to the differences in economic development between the two countries in question, seeing as Montserrat is a far less economically developed nation than Sicily, the preparation and responses for the volcanic eruption were not as extensive far less effective than the preparations and responses to the volcanic eruptions of Mount Etna in Sicily, shown by the amount of deaths in...

1245 words - 5 pages communities to allow for easy escape and access. Volcanic hazards can be more easily planned for than earthquakes, as there are visible signs recorded by observations and various instruments. An example is the tiltmeters which were successfully used in the prediction of six eruptions of Mt St Helens between June 1981 and August 1982. This allows volcanologists to predict when a volcano may erupt and thus set into action any evacuation plans. Mt St
