A hazard is a geological process or phenomenon that may cause loss of life, injury or other health impacts, property damage, loss of livelihoods, social and economic disruption or environmental damage. All of these can be compromised by a volcanic eruption as it can cause deaths, illnesses and destruction of infrastructure, farmland and the economy of the area. However there are many factors involved that can cause differences in the severity of destruction caused by a volcano such as, settlement, monitoring, plate boundaries and the economic wellbeing of a country.
One factor that would cause differences in the hazards posed by volcanoes is the location and therefore the aspects of the area around. For example, Eyjafjallajökull is located in Iceland meaning that the volcano is covered by a large glacier. This added to the local hazards due to when the volcano erupted the glacier melted causing major ...view middle of the document...
These considerations can also be applied to Montserrat which is a LEDC contrasting with Iceland which is an MEDC. The hazards for this eruption were only localised to this location but this eruption had a much more damaging impact. This was because this eruption actually created a death toll, this was because an LEDC lacks the monitoring and responses as the area is not as advanced which means that the country is not able to act as quickly when a hazard occurs, which thus makes it more hazardous.
Another factor that effects the hazards of a volcano is the population density and the levels of urbanisation within the surrounding areas of the volcano as this means that there is a greater numbers of lives and infrastructure at stake because Eyjafjallajökull is in Iceland so it would normally have been low risk as only a few thousand people would have been effected. However, in this case it has a rather major effect despite the fact most of the effects were further way. But these effects were easily prevented compared to the 500 people that had to be evacuated from the surrounding area. On the other hand, in Montserrat there was a much bigger local effect as it has a higher population density meaning that it also had an economical effect for the local area as there was a huge collapse in tourism and also within unemployment as it rose from an average rate of 7% all the way up to 50% as it was causing respiratory problems which forced people to leave. This leads to another point about the response to this as people were not provided with masks to protect them from breathing in some of the ash which could cause major health problems within the area making it very hazardous. Whereas in Eyjafjallajökull they were given these which is a better response as this helps to reduce the hazards posed by a volcanic eruption.
In conclusion, there are many factors that can influence and cause differences in hazards such as severity of the eruptions location and many other factors such as management and responses to the event by the local area.
