how volcanic eruption affect society?
475126
Explosive volcanic eruptions pose both short-term and long-term hazards. ... On longer time scales, eruptions can inject massive quantities of ash into the atmosphere, greatly reducing the solar heating of the Earth and potentially interrupting the global food supply for several years.

Iceland volcano ash cloud triggers plankton bloom. The 2010 Icelandic volcanic eruption, which disrupted European flights, also had a "significant but short-lived" impact on ocean life, a study shows. Ash from the Eyjafjallajokull volcano deposited dissolved iron into the North Atlantic, triggering a plankton bloom.

Volcanic ash or dust released into the atmosphere during an eruption shade sunlight and cause temporary cooling. Larger particles of ash have little effect because they fall out of the air quickly. Small ash particles form a dark cloud in the troposphere that shades and cools the area directly below.

Volcanoes can provide people with many benefits such as: volcanic rock and ash provide fertile land which results in a higher crop yield for farmers. tourists are attracted to the volcano, which increases money to the local economy. geothermal energy can be harnessed, which provides cheaper electricity for locals.

This eruption caused the melting of large amounts of ice, leading to flooding in southern Iceland. ... One of the main effects of the eruption and the ash cloud that followed, was the closure European airspace for seven days.

Floods have large social consequences for communities and individuals. As most people are well aware, the immediate impacts of flooding include loss of human life, damage to property, destruction of crops, loss of livestock, and deterioration of health conditions owing to waterborne diseases.

Volcanic eruptions can be extremely damaging to the environment, particularly because of a number of toxic gases possibly present in pyroclastic material. It typically consists mainly of water vapour, but it also contains carbon dioxide and sulphur dioxide gas.

When that happens, the Earth's surface is subject to natural disasters. Events such as earthquakes, volcanoes and tsunamis all result because of plate tectonics.

Volcanic activity and volcanic eruption is usually triggered by alterations of tectonic plates, resulting in landslides or earthquakes. Volcanic eruptions can be extremely damaging to the environment, particularly because of a number of toxic gases possibly present in pyroclastic material.

Volcanoes contribute to long-term global warming and short-term global cooling. When a volcano erupts, it spews ash and aerosol droplets into the atmosphere. ... As the sulfur dioxide is converted into sulfuric acid, it creates aerosol droplets, which further reflect the sun's rays away from Earth and contribute to cooling ...

Gaseous emissions from an erupting volcano can suffocate, poison, or induce health problems among humans and animals. ... Lastly, large amounts of volcanic ash repeatedly ejected into the atmosphere can disrupt the weather, reduce visibility, and cause harmful effects upon air travel.

Volcanic eruptions can affect climate in two main ways. First, they release the greenhouse gas carbon dioxide, contributing to warming of the atmosphere. But the effect is very small. Emissions from volcanoes since 1750 are thought to be at least 100 times smaller than those from fossil fuel burning.

When a volcano erupts it throws out a lot of ash. At short notice this ash can be very harmful to the environment, but on the long term the ash layer, which contains many useful minerals, will be converted to a very fertile soil. Nearly everywhere volcanoes are located people use the rich soil for farming.
285715
Explanation: Volcanic eruptions release sulfur gases. These gases combine with the water vapor released by the eruption and the water vapor in the atmosphere to form sulfurous and sulfuric acid. ... The fine particles and gases released by volcanic eruptions cause air pollution.

['Volcanoes are dangerous. They can kill people and damage property.', 'Economic activity can suffer as it is hard for businesses to operate after an eruption.', 'Habitats and landscapes are damaged by lava flows.']

Major health threats from a volcanic eruption The most common cause of death from a volcano is suffocation. Volcanic eruptions can result in additional threats to health, such as floods, mudslides, power outages, drinking water contamination, and wildfires.
