18 Significance of Vulcanicity to human activities, compiled here. Vulcanicity is the process through which solid, liquid, or gaseous materials are forced into the earth’s crust or onto the earth’s surface due to high temperature and pressure. Before digging into the 18 significance of vulcanicity to human activities, let’s look at the causes of vulcanicity.

Causes of vulcanicity

Faulting it creates cracks or fissures which allows the movement of materials under high pressure and temperature.

High temperature it causes solid rocks to change into molten materials.

High interior pressure– it is released during the process of earth movements. Water coming into contact with hot materials beneath hence it turns into gaseous form.

Earth movements/ plate movements the crust is weakened hence giving way to magma.

The above are some of the causes of vulcanicity. We can now look at the 18 significance of vulcanicity below. Let’s begin with the positive significance of vulcanicity.

Positive significance of vulcanicity

1. The features resulting from volcanic process like volcanic plug, geysers, volcanoes, and more. They offer scenic beauty which attracts tourist hence earning the country foreign exchange.
2. Vulcanicity can lead to production of geysers and hot springs which can be harnessed to produce geothermal power. The power can be used in both domestic and industrial purposes.
3. Vulcanicity leads to rock metamorphism hence producing valuable minerals for mining.
4. When volcanic rocks undergoes weathering process, it may produce fertile volcanic soils which can be used in farming. For example, tea, horticulture, coffee and more.
5. Volcanic rocks like phonolites are valuable raw materials for building and construction.
6. The windward side of volcanic mountain receives heavy orographic rainfall. Therefore, it encourages settlement as well as farming.
7. Volcanic lakes are sources of fish. Therefore, they act as sources of food/fish. It’s absolutely one of the 18 significance of vulcanicity.
8. Some mountains formed from vulcanicity are forested and ice capped. For example, Mt Kenya forming catchment areas for rivers. Therefore providing water for industrial, agricultural, and domestic purposes.

Negative significance of vulcanicity

In our list of 18 significance of vulcanicity to human activities, below are the negative significance.

1. Volcanic eruption causes the loss of both human and animal lives.
2. Vulcanic eruption may also lead to destruction of properties, i.e buildings, transport networks, and more.
3. Lava flow may bury minerals
4. It may also result into emission of poisonous gases that may result into death.
5. It causes tsunamis/sea waves that may drown coastland or island.
6. The leeward side of volcanic mountains may experience shadow effects on the leeward side hence causing dryness which will discourage agriculture.
7. Volcanic features like volcanic mountains, may create barrier to transport and communication hence making it expensive.
8. Volcanic landscape form rugged nature which discourage settlement and agriculture.
9. Lava flow may also cover agricultural land
10. Eruption of volcanic ash and dust into the atmosphere may affect air transport.
