Volcanic eruptions can have devastating consequences, especially in less economically developed countries (LEDCs). These countries often lack the resources and infrastructure to adequately prepare for and respond to a volcanic eruption, making them particularly vulnerable to the impacts of these natural disasters.

One example of a volcanic eruption in an LEDC is the 2010 eruption of Mount Merapi in Indonesia. Mount Merapi is one of the most active volcanoes in Indonesia, and its eruptions have caused significant damage and loss of life in the past. In 2010, the volcano erupted for several weeks, spewing ash, rocks, and lava down its slopes and into nearby villages. The eruption killed over 350 people and forced over 350,000 to evacuate their homes.

The impact of the 2010 Mount Merapi eruption on the local community was significant. Many homes and buildings were destroyed by the ash and lava, and the eruption disrupted transportation and communication networks, making it difficult for people to get the help they needed. The ashfall also contaminated local water sources, causing health problems for those who were exposed to it.

The government of Indonesia responded to the eruption by providing emergency shelter and supplies to those who were affected, but the recovery process was slow due to a lack of resources and funding. Many people were left without homes or means of livelihood, and the long-term economic impact of the eruption was significant.

Volcanic eruptions in LEDCs can have a disproportionate impact on the local population due to a lack of resources and infrastructure to prepare for and respond to these disasters. It is important for governments and international organizations to provide assistance and support to communities affected by volcanic eruptions in order to help them recover and rebuild. In addition, it is important to invest in infrastructure and emergency preparedness measures in order to reduce the impact of future volcanic eruptions on LEDCs.

Comparisons Between LEDC's and MEDC's

Many LEDC's depend on agriculture to sustain their economy, and also many farmers need crops to feed themselves. This is in contrast to the volcanoes found in Hawaii which have slow flowing lava eruptions and few if any massive explosions. But they've been less successful in boosting the damaged local economy for the long term. Without support from MEDCs and international aid agencies, LEDCs like the Democratic Republic of the Congo remain trapped by both the potential of natural disasters and their devastating reality. Impacts of an Earthquake in an LEDC An LEDC will be dealt significant damage from an earthquake.

These superior precautionsalso usuallyresult in less casualties in terms of the overall population. Smaller communities to the southeast such as Chubut and Rio Negro also received heavy ash falls. The ash cloud was up to 17 kilometers high and was visible on satellite images for hundreds of kilometers over the Atlantic. A LEDC is a less economically After an eruption, the MEDCs are usually quick in clearing up all the ash and rebuilding homes for the people, whereas, for the LEDCs it can be difficult and may take a long time. About 4,000 people who lived there were evacuated by boat. Once the explosion went off, it lead to a blast that generated a 2.

Many of the buildings will collapse from the earthquake, and a large number of people will be unjured or dead from their roofs caving in on them. Later, as the lava began to cool, residents returned to Goma to protect their homes from looting. Without support from MEDCs and international aid agencies, LEDCs like the Democratic Republic of the Congo remain trapped by both the potential of natural disasters and their devastating reality. After the eruption has taken place, steps to slow the lava flow or divert it may also be taken to protect important areas of a country from being damaged or destroyed. A densely populated area, more than 300,000 people had to be evacuated, and nearly 120,000 people were left homeless.

The major impact was on farming, and many farm animals were killed by suffocating on the ash. These columns were accompanied by pyroclastic flows, lahars, and abundant ash fall. LEDC United Nations observers warned of a 'human catastrophe' with no shelter, electricity or running water for evacuees. The long term response to this eruption was that Chile's geological survey the Servicio Nacional de GeologĂ­a y MinerĂ­a, or SERNAGEOMIN created a new program to improve monitoring and hazard mitigation at 43 of Chile's high-threat volcanoes. A fellow LEDC, or Less Economically Developed Country. These are the causes of this volcano, which is explosive because the lava is Rhyolitic, has high gas pressure and high Silica content.

The city of Goma suffered some of the worst devastation, w ith around 80% of its commercial infrastructure destroyed. However, this is only possible where the lava is slow moving and there is sufficient warning, this often requires high tech equipment to monitor where the lava will be and at… Comparing Mt. By late May the lava eruptions had created a new dome of 540,000m 2 containing 55million m 3 of material. A densely populated area, more than 300,000 people had to be evacuated, and nearly 120,000 people were left homeless. Impacts of a Volcano in an LEDC Due to lack of resources, a LEDC often does not have the sufficient means to detect volcanic activity, other than from other MEDC countries. Transcript Mount Nyiragongo Democratic Republic of the Congo Mount Nyiragongo is a highly active volcano in the Democratic Republic of the Congo.

This is a destructive margin, where the denser Nazca plate is subducted beneath the Less dense continental lithosphere of the South American plate. Construction laws in some earthquake-prone counties e. At this margin, clearly marked on the map and cross section opposite, there is oceanic to continental convergence. Its eruption in 2002 caused widespread devastation, y et much of the damage could have been prevented. Chaitén was classified as a low threat volcano, but even without this low rating there is only one volcano observatory in all of Chile, this affects the prediction of such events. The mudflow and lava that would follow would kill many animals and 57 people.

Chaitén was classified as a VEI of 4. Many studies have been done that show there is a large rotating block under it which causes friction that was likely the cause of the eruption2. The town of Futaleufu, with about 1,000 residents, was also evacuated. Volcanic eruptions happen all across the surface of the globe, many argue that if controlled and monitored they would have little effect on the population. Indeed, Chaitén was a major concern to both the airline industry and the neighbo u ring country of Argentina. Earthquakes in MEDC's are generally not as destructive as the buildings that are built are more earthquake resistant.

As the plate descends it causes earthquakes in the Benioff zone, and volcanoes occur here because of melting of the plate in the asthenosphere. And, with no prior warning, the authorities struggled to cope, leaving many to sleep on the streets. Helens which is located in the pacific northwest of the United States. They struggle to implement effective recovery or future prevention measures leaving them at greater risk. In addition, Lahars volcanic ash mud flows had cut communications in areas and made access difficult whilst ash falls up to 15cm deep had blocked rivers and contaminated water supplies. Long-term Responses After a natural disaster, many LEDCs become reliant on aid from MEDCs, or more economically developed countries. This area of Chile has reasonably low population density, so limits the potential impacts on the local scale.

Those who do survive tend to be displaced from their homes and have nowhere safe to stay. These are usually an early warning sign of volcanic activity - but no action was taken. This low angle of subduction may explain the relative lack of volcanic activity in the northern part of Chile, compared to the extremely active southern volcanic mountains, which was the cause of the Chaitén eruption. In addition, volcanic ash from the eruption clouds caused ground transportation and health problems in Chile and Argentina. As a result the death toll and damage dealt to infrastucture and buildings can be extremely high. Its eruption in 2002 caused widespread devastation.

It is located on the West coast of South America approximately 150km East of the Peru Chile Trench. Due to all of these preventive measures the number of people who die from volcanic eruptions tend to be quite low, and the damage dealt to main infrastucture is also minimised. The city of Goma suffered some of the worst devastation. Primary Effects For over a week before Nyiragongo erupted, local people felt tremors and small earthquakes. For example when Mt.
