What are the impacts of volcanic eruptions on the society environment and the economy?
Among the hazards in distant areas are the effects of toxic volcanic ashes and problems of the respiratory system, eyes and skin, as well as psychological effects, injuries, transport and communication problems, waste disposal and water supplies issues, collapse of buildings and power outage.
What impact does a volcano have on the environment?
The gases and dust particles thrown into the atmosphere during volcanic eruptions have influences on climate. Most of the particles spewed from volcanoes cool the planet by shading incoming solar radiation. The cooling effect can last for months to years depending on the characteristics of the eruption.
What is the benefits of volcanic eruptions that promote tourism?
They can destroy farms, villages and even towns. But they can also have advantages: – Volcanic ash contains many minerals which make the soil very fertile, – the earth’s crust around a volcano is so thin that it easy to win energy from the heat of the earth, – and volcanoes attract tourists.
