Mount Etna Case Study. The impact of the event social, economic, environmental , in the short and longer term. You might be asked to consider the values and attitudes or opinions of people involved in the eruption, such as refugees or aid workers for example. It is the most southerly volcano on mainland Iceland before Surtsey in the sea to the south west. Britain had fine anticyclonic weather for a lot of the time that the Ash cloud existed.

Mount Okmok in Alaska’s Aleutian Islands. It is the most southerly volcano on mainland Iceland before Surtsey in the sea to the south west. Here, convection currents are driving apart the North American plate moving West and the Eurasian Plate moving East along a constructive or divergent plate boundary. Volcanic hazards case study: The main risks are to livestock through fluoride ingestion from volcanic ash on pasture.

These are perishable goods and they are transported by plane to keep them fresh but the flight ban meant that products returned unsold and destroyed. Britain had fine anticyclonic weather for a lot of the time that the Ash cloud existed. This means that many stuey the countries have great capacity to cope in terms of making predictions and preparing alternatives for companies and people stuck by the restrictions on air travel.

Mount Nyiragongo DRC There is a volcanic area located in the south of the island on Soufriere Hills called Chances Peak. Mount Okmok in Alaska’s Aleutian Islands.

The small population of the island 11, people was evacuated in to the north of Montserrat as well as to neighbouring islands and the UK. The nature of the volcanic hazard — type, frequency, magnitude.

Shield volcano Erupted on the 12th of July, without any warning.

The IMO’s weather radar on the southwest tip of the country showed the height of the ash plume, which is important for calculating the distribution of the ash. The major problem with this volcano was volcanic ash and the ash plume that resulted from the eruption.

List of case studies for; Tectonic plates, Weather and climate, Development and globalisation and Conflict. There were also pyroclastic flows that traveled down the flanks of the volcano. Sign up to Comment. The graphic shows the progress of the eruption and its impact on the island. Finally, many companies had contingency plans in place for an emergency such as this, so could cope better, Tesco circumvented the ash cloud by flying Kenyan produce into Spain and then using road haulage for example.

Inthere were shallow focus earthquakes and a large ash cloud. Scientists were very concerned at the time of the eruption that this eruption could be a precursor or warning sign of a much larger eruption of the historically more active and dangerous Katla. That means that the countries affected by this hazard responded by medf or collectively, and had the capacity to do so.

It erupted in late and early which resulted ins several major episodes of lava fountaining with ash emissions and explosions on the Eastern side. The ash contaminated local water supplies and farmers near the volcano were warned not to let their livestock drink from contaminated streams and water sources, vllcano high concentrations of fluoride from the ash mixed with river water can have deadly effects, particularly in sheep. Although the casd cloud was invisible to the naked eye, as it is made up of very fine particles and substances.

Although the 1,m-high volcano has erupted during historical time, it has been less active than other volcanoes of Iceland’s eastern volcanic zone, and relatively few Holocene lava flows are known. This volcano erupts more often and is known to be more violent. The London office gave information on ash which is based volano information from the Icelandic Met Office.

Volcanic eruptions and lahars have destroyed large areas of Montserrat. Between March the 3 rd and 5 th of there were plenty of warning signs of an eruption, as there were over 3, recorded earthquakes, the vast majority of these being less than 2 on the Richter scale and only some large enough to be felt in nearby towns. Over 1 million flower stalks were unsold in the first two days and over 50, farmers were temporarily unemployed as their beans and peas could not be sold.

Indeed, visibility was down to a few metres and local cattle farmers suffered.

The major impact was Internationally however, as winds redistributed the ash that was pumped high into the atmosphere over Northern and western Europe and stopped flights from taking off. Volcanic hazards case study: Pilean eruption – basaltic lava.

This was a problem because winds would have dispersed the cloud better. You might be asked to consider the values and attitudes or opinions of people involved in the eruption, such as refugees or aid workers for example. The plates are moving apart at a rate of 1cm to 5 leve per year.
