Harmful and beneficial effects of volcanic eruptions examples



  1. 0 Votes

    Volcanic eruptions can be harmful to the life immediately around the area. The lava can burn and cover vegetation, animals, and people. Buildings, and even entire cities, may be destroyed. For example, the eruption of Mount Vesuvius in A.D. 79 covered the entire cities of Pompeii and Herculaneum with volcanic ash and rock, marking the end of their existence. Volcanic eruptions can release huge amounts of particle matter into the air, leading to asphyxiation of life. Enormous eruptions can cloud the air so much that planes can’t fly for days or weeks. If a supervolcano exploded, the dust in the air might be so thick that it affects the amount of sunlight reaching the Earth; this could pose a threat to all life.

    However, volcanic eruptions can also build land, such as the islands of Hawaii, that are comprised of nutrient-rich soils. Valuable gems and metals, like diamonds, opals, gold, and silver may be found at volcanic sites. Additionally, volcano heat can be utilized for geothermal power or for hot springs. People may enjoy hiking up volcanos or skiing down them. Additionally, volcanic eruptions release high amounts of water vapor, which can augment the world water supply.
