The relevance of time and location can play a huge role towards the levels of hazards and consequences that occur when related to a volcanic eruption. Within this essay I will consider all contributory factors that may influence the processes which take place. Contrasting several volcanoes with specific differences, in both LEDC’s and MEDC’s will give a vivid and overall representation of the variation 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 timeframe to another. As do the types of hazards, which are categorised into primary and secondary. Primary hazards, created by the direct eruptive energy of the volcano could include pyroclastic flow, ash clouds and large volcanic bombs. These primary hazards can in turn trigger secondary hazards such as floods, fires, disease and destabilisation of infrastructure.
Another factor that could suggest the seriousness 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 that has elapsed since the last activity. Perhaps the eruption was basaltic, this originating largely from the upward movement of mantle material. They are most common along spreading ridges but are also found at hot spots and within more developed rift systems. These types of volcanic eruptions are of a basic level. The lava here wouldn’t be at the top end of the risk scale as it spreads slowly and smoothly as the liquid is of a runny form. However, if the eruption was classed as andesitic it would be marginal...

...ye on the volcano for twenty years with a well known network of remote sensors, radio and phones to the centre in Catania. Communication in this area is vital and is their main ingredients to decrease deaths, disease and destruction.
In conclusion, I believe that the preparation and awareness of what is about to happen, with regards to a volcanic eruption, is the key to a less unfortunate event. Monitoring systems and predictions are vital in order to limit the amount of deaths and infrastructure of buildings as well as the land. Usually this will only apply to MEDC’s and using my own knowledge and research in which I have hi-lighted in my chosen case studies. However, volcanic processes will affect people continuously around the world. Wealth and organisation will lower the representation of hazards which is typical in more economically developed countries.
There are many pro’s for attempting to forecast an earthquake or volcano. Forecasting an earthquake or eruption saves lives and property, mainly by preparation, as there is no way to prevent these events with today technology.

On May 22, 1915, an explosive eruption at Lassen Peak devastated nearby areas and rained volcanic ash farther 200 miles to the east! This explosion was the most powerful in a series of eruptions from 1914 through 1917. ...
Volcanoes have always been a mysterious wonder of the world. Volcanoes have shaped the landscape and the very ground that we all live on. People have written stories of their disastrous eruptions, and painted their marvelous shapes on canvas. The essay will outline some of the more famous volcanoes and how they have impacted are history. Mount Vesuvius that destroy the great city of Pompeii, Krakatoa they spewed deadly ash on small village town, and Mount St. Helen, the only volcano in my own country to every erupt during my own time period.
The first time I saw Mt. Rainier for myself, was last summer when my boyfriend and I drove to Washington. It was the most beautiful, peaceful looking mountain I have ever seen. However, underneath it's great beauty, it hides a deadly secret. Mt. Rainier is one of the most dangerous volcanoes that we have here in the United States. One of the reasons it is so dangerous is because of it's great beauty. People enjoy looking at it, and the area that surrounds it, so they have made their homes here. Mt Rainier is not the only volcano I am interested in, in fact this last summer I also went to Mt. St. Helens and Crater Lake. But it is the volcano I chose to research for this paper because it does have so much beauty and at the same time so much power. I already know the basics about volcanoes, how they form, the different types, etc., but I wanted to find out more about what would happen if this great volcano were to erupt, what type of eruption would it be, and how would it affect the people that live around it.
Some other factors include slope deformation of a volcano and an increase in gas emissions. Movie fact of fiction: Is the eruption depicted in Dante’s Peak
Although volcanoes are difficult to predict, geologists have made many efforts in order to caution the people of Orting and other surrounding towns of possible lahar slides. Residents have been made aware of emergency response plans and they know the proper precautions to take in the case of a volcanic activity emergency. Sirens have been put in place by the fire department and governing bodies of surrounding communities to detect volcanic activity and warn the community of possible slides.... ... middle of paper ...
Many of us know Mount Shasta to be a beautiful mountain and a popular tourist location in California. However, this mountain is much more than that, this mountain is actually a volcano. Volcanoes come with a number of hazards and a volcano of this size is of no exception. Previous eruptions on Mount Shasta have given us an idea of the power this volcano has and the damage it may do. With this information scientists are able to predict what may happen should another explosion occur.
Stories about volcanoes are captivating. Myths come in different versions, but all of them are capable of capturing yours, and everybody’s imagination.
Volcanoes are one of natures most interesting and dangerous phenomenons. The way volcanoes operate can be understood, on a basic level, by just some simple physics and chemistry, this paper will investigate and explain some of the basic physics that govern the behavior of volcanoes.
Volcanoes are one of the most destructive forces on Earth. It is estimated that some 500 million people live near active volcanoes (Lutgens and Tarbuck, 2013). Of the Earth's known volcanoes, 70 are expected to erupt each year with at least one large eruption each decade (Lutgens & Tarbuck, 2013). As populations continue to increase and more people are attracted to the beauty surrounding these areas, the immediate threat to humans from these sometimes sleeping giants grows. Due to this, the study of volcanoes and the service that volcanologists provide to the public by way of information and predictions on activity is immeasurable.
Volcanoes can cause damage by spewing lava, but earthquakes before the eruption can also cause damage. These earthquakes open fissures and let magma out to the surface. When the magma exits these fissures, streams of lava up to hundreds of feet can shoot into the air. The picture below shows the lava erupting from the fissures created by the earthquakes in...

When a volcano erupts, the focus is particularly on the consequences that take place near the volcano, such as weather conditions, the impact on nature, and the people who are affected. The noticeable changes that take place after a volcanic eruption includes the decrease in the temperature, natural disasters, such as tsunamis, droughts, and hurricanes, and the air pollution, which can be harmful to plants, animals, and people.
