Volcanoes are basically caused by chemical activities taking place in the earth’s crust. The immediate surroundings of a volcano experience the most direct effects of an eruption. This is precisely accurate in the case of a fire ring in the Pacific ocean where 75% of volcanoes are found in the Earth. The effects of volcanoes on the environment depend on climate patterns, the overall scale of the eruption and how much the gases spread. Causes Erupting volcanoes can pose many hazards, not only in the immediate vicinity of the eruption. Depending on the size of the eruption you could be looking at a volcanic winter. People often have to be evacuated. However, it currently … Example: Chaparrastique volcano in El Salvador started erupting on 29 Dec 2013. volcanic eruptions have some positive effects, unlike any other natural disasters. The 1980 eruption of Mount St. Helens vented approximately 10 million tons of CO 2 into the atmosphere in only 9 hours. Let us see some negative effects of volcanoes: Eruptions occurring close to human settlements may spill and destroy lives and property. Of course, they also have negative effects. These are usually located where tectonic plates meet.

Effects Of Supervolcanoes When the ash falls down, it blankets the land, including agriculturally … Anyone living within 2 miles of the volcano is evacuated. Our global society is now very different to that affected by past, modest-sized volcanic activity and is highly vulnerable to catastrophic damage of infrastructure by natural disasters. According to a Prezi presentation published by R’smond:) Rachmaninov, a volcano is a mountain that opens downward to a pool of molten rock below the earth. A volcano eruption is the escaping of molten rock through a rupture in a mountain on the Earths’s surface. There is no question that very large volcanic eruptions can inject significant amounts of carbon dioxide into the atmosphere. Together with volcanic gases it impairs people's ability to breathe. That ash can cause breathing problems to people living near the volcano. In short, tropical volcanic eruptions tend to induce a large precipitation decrease in summer monsoon (wet) regions mainly through the moisture reduction and the monsoon circulation weakening. Although volcanic eruptions cause massive damage to their surrounding environments, there is a positive side to these activities. Cloud of ash and lava are coming out of a Volcanic eruption. Another problem the environment is the ash that is released when a volcano erupts. Volcano eruptions make several negative effects and also positive effect. Negative Effects Of Volcanoes: When a volcano erupts, there will be a high chance of ash spreading around the volcano for certain kilometers. Explo­sively ejected ash disperses in the air. Volcanic eruption occurs when pressure builds up. These are usually located where tectonic plates meet. This essay will discuss the causes and effects of volcanic eruptions. This is specifically accurate in the case of the Pacific Ring of Fire where 75% of the earth’s volcanoes are found. A volcanic eruption occurs when pressure accumulates.
