harmful effects of volcanic eruption

Large scale destruction: A volcanic eruption causes large scale destruction to the surrounding area. Helps economies grow: Volcanoes provide fertile soil which then translates to more produce which translates to more money coming into an economy. The climactic June 1991 eruption of Mount Pinatubo, Philippines, was the largest volcanic eruption in this century to affect a heavily populated area. This volcanic ash is very dense and creates unbreathable air. Sulfur dioxide, carbon dioxide and hydrogen are released in smaller amounts. TAAL ERUPTION – The Department of Health (DOH) released a reminder to the public regarding the health effects of ashfall and how to cope with this. This method was proven when it was done in Iceland during an eruption in 1983. Flow and surges of boiling lava, red-hot rocks and other pyroclastic materials burn or totally engulf people or objects they encounter. Volcanic Eruption Harmful Effects Before. The most obvious is not to build towns around a volcano even if the soil around volcanoes are fertile as volcanic eruptions do more harm than good to you. Inhalation of volcanic ash can be very detrimental to human health, due to the harmful aerosols and poisonous gases the ash is made up of. Volcanic eruption can cause three climate effects such as ozone depletion, cooling effect and global warming. These may develop very early in the volcanic eruption, and may even be among the first indicators that an eruption is imminent. Gaseous emissions from an erupting volcano can suffocate, poison, or induce health problems among humans and animals. After volcanic eruptions occur there is a large amount of volcanic ash that can envelop the surrounding area. Parameters associated with blooms and fishery damage were sunspot number, El Niño/La Niña events, Kuroshio Current, and volcanic eruptions in the South China Sea … The flowing lava and other conditions also leave these areas uninhabitable for quite some time. More From Reference.

Volcanoes also don’t give enough time for people to react. Tourists flock to these to climb the sides and to experience the landscape. It helps to create tourism... Volcanoes also provide nutrients to the surrounding soil. Lava flows and lahars can wipe out the flanks of mountainsides. Water vapor, the most common gas released by volcanoes, causes few problems. The blast from an explosive eruption can knock down trees, destroy buildings, and kill humans and other animals. Big eruptions can also cause global cooling--even to the point where crops won't grow--if enough volcanic dust enters the atmosphere and reduces the amount of sunlight reaching the ground. Numerous cases of deaths and injuries from accumulated ash in the roof were reported after the same Mount Pinatubo eruption. There is also the flow of lava, which when people come into contact with kills them almost instantly. Volcanic materials also be used to create decorative articles like figurines. During a heavy storm or typhoon, lahars are produced when rain mixes with volcanic debris. They produce ash, lava, volcanic … These geothermal plants are run by super heating water underground close to where magma resides. There is lot of damage to property and after big eruptions the surrounding area becomes unusable for a very long time. Lahars and volcanic debris avalanches. The ash could also cause severe damage to str… Lahars can also accumulate in rivers and other waterways and cause floods. Some of these minerals that become ground nutrients are oxygen, phosphorus, nitrates, silica, potassium, calcium, iron, and magnesium. Local businesses would also welcome the influx of visitors who not only come to appreciate the volcanic scenery but at the same time somehow add revenue by patronizing the food and services offered. Also, a volcano is formed overtime when more lava cools on top of already cooled lava. People who survived the explosions are known to have perished by suffocating after the explosion by just staying in the surrounding area. These super-heated materials can likewise damage or totally destroy houses and other buildings, farmlands, and crops, as well as infrastructures. Some of the toxic gases that are released are carbon monoxide, hydrogen chloride, and hydrogen fluoride. Flow and surges of boiling lava, red-hot rocks and other pyroclastic materials burn or totally engulf people or objects they encounter. According to the DOH advisory, volcanic ash has carbon dioxide and fluorine which can cause numerous harmful health effects to a person when exposed to it. Maintaining the Planets balance: Mother nature has her own ways of balancing the planet and keeping it sustainable. In countries like ice land, geo thermal power is responsible for generating 80% of the entire grids power. In 1973, a volcanic eruption buried the town of Heimaey in Iceland. Geothermal energy Positive Effects of Volcanic Many dormant and active volcanoes attract hundreds of thousands of tourists each year. All land mass on earth was created by volcanic eruptions. The size and magnitude of the volcanic eruption and the proximity of the neighboring town play a role in the volcano's ultimate scope of destruction.
