Introduction of TOPIC

Response to this continuous volcanic activity from July 1995 to July 1999 on Montserrat, one of the lesser Antilles islands in the Caribbean has to be looked at in sequence of events and in terms of short and long term management to be analysed and measured in levels of success. Immediate response and management e.g. evacuation after the first phreatic eruption on the 18th July 1995 was well managed as they took pre-cautions as ‘the preservation of human life is always top priority’ however it is the management of this evacuation in the following volcanic events where the standards decreased as people returned to their homes. Long term management such as the three year development plan funded by the UK was a significant step in Montserrat’s recovery however you can argue that this wasn’t significant enough as it was met with conflict and ‘rioting’.

Short term management has been relatively successful, especially in in August 1995 where 5,000 people were evacuated as a pre-caution after the phreatic eruption of ash and steam in July, troops from the USA and British Navy came to aid this process and emergency aid was given from the UK Government for temporary buildings, schools, clean water, medical services and food. The Montserrat Volcano Observatory was also setup consisting of seven station which advised residents to move North in August 1997, saving lives from the following eruptions.

They monitored the changes in the volcano such as the swelling and deflating of the dome with equipment such as a tilt meter and an extensive 24/7 seismograph network which allowed them to predict the lava dome collapse which happened on the 25th June 1997. This dome collapse created the biggest eruption Montserrat has experienced causing pyroclastic flows, avalanches of gas and rock and a volcanic surge, immediate response was from a helicopter rescue which collected 20 trapped people in the exclusion zone and warning systems including sirens and the radio which encouraged people to move to high ground. This exclusion zone was crea

considered safe, the rest being an exclusion zone including Plymouth, and this proved successful in August 1997 when Plymouth which was previously a safe zone was destroyed by pyroclastic flows.

Long term management is ever-changing and developing due to the sustainable development plan 2008-2020 with an aim to achieve a sustainable population which so far has proved successful in encouraging immigration which allowed 1,500 people from other Caribbean islands to move to Montserrat and by increasing tourism which Montserrat by creating a new airport and hotels. Along with this sustainable development plan there was a three year development plan funded by the UK which aided the reconstruction and relocation of the capital at Little Bay, houses, schools such as the community college opened in 2005, infrastructure such as the development of Salem, medical services e.g. the large hospital in St Johns which are helping those who experienced health issues such as silicosis and clean water projects which has prevented disease. Plymouth and the whole of the South has been maintained as an exclusion zone as a caution which could be considered successful due to the on-going volcanic activity such as in September 2000. The annual aid budget of £16.4 million from the UK and EU proved essential in 2008-2009 when the residents ‘relied upon’ it.

Despite the success in certain aspects of short term and long term management, there were particular areas which were not so successful. After the prompt evacuation in August and December 1995 the residents of the South were allowed to return putting their lives in danger in January 1996 as two months later pyroclastic flows burst out of the volcano causing the residents to once again evacuate. The exclusion zone was not enforced strictly enough as 19 people were killed on the 25th June 1997 who returned to their homes in the danger zone, this proves that the hazard maps can only be successful if the residents co-operate. The warning systems used throughout these volcanic events such as the sirens were not very useful for those living in the danger zones beyond Plymouth for example Farrels yard. Although the majority of the long term management was successful and significant in the re-development of Montserrat, the £2400 per person was met with riots due to the bad living conditions in the North. One of the main reasons for the death and destruction from these volcanic events is due to the failure of the government to act quicker. Professor Geoff Wadge predicted in the 1990’s the eruption of the Soufriere Hills and advised moving the South’s infrastructure to the North however he could only predict a 1% chance therefore this was not acted upon.

Overall the management and response to this volcanic activity predicted danger, saved lives and is still giving hope to Montserrat’s survival with reconstruction and aid to encourage sustainability. The Montserrat Volcano Observatory were the most successful form of management which put their lives at risk by entering the exclusion zone and examining the crater. Although there was 19 deaths we must take into account the erratic nature of the eruptions and the volcanic surge which was unexpected and could not be predicted before it took place.

Volcanic Hotspots Presentation

The important point to understand is that the plume is stationary. The point where the hot material breaks out of the mantle and on to the surface stays in the same place. However, where it reaches the surface changes with time, because plates move , as the theory of plate tectonics tells us. Above the hot spot a volcano forms and grows and grows until the plate carries it away. Once the volcano has been carried away and no longer sits over its hot spot, it loses its source of magma. A new volcanic cone begins to form on top of the hot spot. A few active volcanoes do exist in locations well away from any plate margin. These are volcanic hot spots . They may be in the ocean, which is where the best known example, the Hawaiian islands , lies. Others are on land, for example the volcanic...

Volcanic Eruptions

Deep inside the Earth, magma rises upwards, gathers in pools within or below the crust and tries to get to the surface. Cracks provide escape routes and the magma erupts as a volcano. Steam and gas form clouds of white smoke, small fragments of rock and lava blow out as volcanic ash and cinder, and small hot bombs of lava shoot out and harden. Not all lava is the same. It may be thick and sticky or thin and runny. Lava thickens or viscosity determines the type of volcanic eruption and the kind of rock that forms when the lava hardens. Some volcanoes are active, erupting at any time; some are dormant or cold, waiting to erupt; others are dead or extinct. Volcanoes have shaped many of the Earth's islands, mountains and plains. They have also been responsible for changing weather, burying cities and killing people who live nearby. Above:...

Mount St. Helens Case Study

Mt St. Helens, one of the 13 active volcanoes around the world (which is one of the most dangerous volcanoes around us). Mt St. Helens is located in Washington, the Pinochet National Forest Park, its spirit lake had attracted massive tourist which made a huge amount of profit for the tours company. The last eruption before the previous one was at 1857 which brought some damage but not as much as the one that took place at 1980. 20th March 1980, a big earthquake occurred. The geologist around the volcano found something was wrong, the volcano was back again. The earthquake occurred because the magma is in a great pressure, full of energy and in a high temperature which was forced to be released. At 31st March, emergency was declared, people who are living 20 square mile were forced to be evacuated, but one man, who's been seen as a...
