Positive and Negative Aspects of Volcanic Eruptions Coursework

• Intensive farming. In the process of ejection of volcanic ash, the earth is enriched due to the content of minerals and useful elements in it.
• The formation of islands. As a result of volcanic explosions in ancient centuries, islands such as Crete, Cyprus, Micronesia, and Hawaii were formed.
• Intensive farming. In the process of ejection of volcanic ash, the earth is enriched due to the content of minerals and useful elements in it.
• The influence of a volcanic eruption on the Earth’s climate. Cooling of the atmosphere is very useful in its properties, especially in case of the problem of global warming. The emergence of geysers has a beneficial effect on warming in those regions where it is so necessary. For example, Iceland, Kenya, Philippines.
• Application in cosmetology. Thanks to the healing and beneficial properties of volcanic ash, high-quality products for personal care products for face, hand, and body care are made. Due to the natural component, the skin is rejuvenated, and acne is eliminated.
• Extraction of precious stones. In volcanic rocks, geologists often find metals such as obsidian, agate, copper, silver, and even gold.
• Use in the construction industry. Volcanic materials are used in the manufacture of cement, plaster additives, and foundation construction (Blong, 1984).

1. Direct social damage includes the death of people, their physical and psychological trauma, and loss of housing.
2. Indirect damage is considered to be the rapid movement of a large number of people, disruption of relations in society, changes in the moral and psychological situation, a decrease in working capacity, and a drop in labor efficiency.

Natural consequences of volcanic eruptions cause huge damage to territories in areas of natural disasters:

• fires at objects of the anthropogenic environment

• breakthrough of reservoirs,
• spills of oil products,
• gas and water leaks,
• emissions of harmful chemical and radioactive substances into the environment (Blong, 1984).
