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.

10 effects of earthquakes to human activities

Leave a comment

10 effects of earthquakes to human activities, compiled here. Earthquake is a sudden and rapid movement, shaking, trembling of the earth’s crust caused by shock waves that originate below the surface of earth. Earthquakes have different sizes from the weak ones to those that are violent enough to affect human lives. Mild earthquakes are referred to as tremors. We have a number of effects of earthquakes as follows.

10 effects of earthquakes to human activities

Let’s go through the 10 effects of earthquake as follows with some of the real life examples. Below are our, 10 effects of earthquakes to human activities.

Destroy buildings

This is a common problem we had to include in our list of 10 effects of earthquakes to human activities. Earthquakes may make buildings to collapse. Normally, buildings are investments of people and also give shelter to human beings. Therefore, when the buildings are destroyed, it’ll affect human beings life. Many will loss their shelters and investments after the damage of those buildings.

Damage infrastructure

When we talk about infrastructure, we talk about roads, water pipelines, gas lines, oil pipelines, and more others. When oil pipelines are broken, it may make oil to spill on the environment. Oil spills may lead to contamination of water and soils. Brocken gas lines may make gas to escape and can cause fire outbreak and explosions.

Loss of lives

The world have experienced several earthquakes over the years as thousands of lives have been lost. A good example is the earthquake that occurred in Turkey and Syria on 6th February 2023. The earthquake had a death toll surpassing 50,000 individuals. It is absolutely one of the 10 effects of earthquakes to human activities.

Restricts the development of towns

This is another great effect of earthquake. We have towns that have gone down in terms of development due to earthquakes. When an earthquake occurs in a town, a number of buildings and infrastructure will be destroyed hence limiting more buildings to be built. Besides that, a lot of resources and money is used to rebuild infrastructure and buildings that have been initially destroyed by earthquakes. Some investors may also avoid towns prone to earthquakes.

Turkey- Syria earthquake

May trigger landslide and rockslides

When large rocks and part of the earth situated uphill are subjected into earthquakes. They may be forced to dislodge and roll down to the valleys. Rockslides and landslides cause death and destroy properties downstream.

Trigger tsunamis

Surely, one of the most hazardous effect of earthquakes are tsunamis. Tsunamis mostly come about when earthquakes occur in oceans, sea, and other large water bodies. One of the most popular tsunami that occurred in the world is in 11th march 2011. That tsunami was experienced in the coast of Japan and it claimed lives of about 18000 individuals.

May cause fire

Earthquakes may also lead to fire outbreak. Normally, fires are linked to brocken electrical and gas lines. Earthquake may break electric and gas lines which may lead to fire outbreak. Moreover, the earthquake may also destroy water pipes which will limit the supply of water to extinguish the fire.

10 effects of earthquakes, image showing fire outbreak.
Fire outbreak after an earthquake

Can result into floods

Earthquakes of high magnitude may make dam walls to crack. Thereafter, the dams may collapse after sometimes making water to flow into the nearby areas hence resulting into floods.

Leads to liquefaction

Liquefaction is a process where the soils become saturated hence loosing it’s strength. Loosely packed Sediments with high water content may be subjected to constant shaking hence loosing their strength. When liquefaction occurs, it may make buildings and structures on liquefied soils to collapse or sink in the ground. An example of liquefaction is the earthquake in 1692, Jamaica. The earthquake resulted into devastation of Port Royal town. It is absolutely one of the 10 effects of earthquakes to human activities.

Raise or lower the sea level

This is also one of the 10 effects of earthquakes to human activities. Earthquakes may lead to displacement of sea flow hence lowering or may even rise the sea level. When sea level is lowered or raised, it may result to either emergence or submergence of coasts respectively.

Final word

The above are the 10 effects of earthquakes to human activities. Some places have experienced strong earthquakes earthquakes that really affected the lives of many. However, minor earthquakes or tremors have no dangerous effects. You can also share your views on the comment section.

15 significance of faulting to human activities

2 Comments

15 significance of faulting to Human activities. Faulting is one of the internal land forming processes taught in geography. I will be taking you through the significance of faulting to human activities. Before that, you have to know the meaning of faulting. What is faulting Faulting is the cracking or fracturing of the brittle crustal rocks due to tectonic forces (tensional and compressional). Faults are cracks or fractures that develop in the crust when subjected to tectonic forces.

Image showing faulting process.

Features resulting from faulting

1) Fault scarp / escarpments

2) Block mountain /Horst / fault blocks

3) Rift valley

4) Tilt blocks

5) Fault steps

The above are some of the features formed through the process of faulting.

Now let’s see the 15 significance of faulting and how those features formed affect human activities.

15 significance of faulting and features formed to human activities

Below are the positive and negative significance of faulting and it’s features to human activities.

Positive significance

  • Faulting leads to formation of features like Horst mountains and Rift valley that form beautiful sceneries. The beautiful sceneries will attract tourists, hence earning the country foreign exchange which will support the countries economy.
  • Faulting will lead to formation of lakes that will act as sources of water for both domestic and industrial use.
  • It will also lead to displacement of rocks, therefore exposing minerals that are mined.
  • Faulting leads to formation of block mountains that receive rain on the windward side. The rain will then give rise to rivers that will provide water for domestic, agricultural, and industrial use, also may generate H.E.P in presence of waterfalls.
  • Faulting creates deep faults which may act as passage for steam jets. The steam jets may be utilized to produce geothermal power.
  • The block mountains resulting from faulting may receive heavy rains on the windward side. The rains may encourage growth of dense forest which provide timber for building and construction.
  • When faulting occurs across a ridge, it may provide a dip which could form a mountain pass where transport and communication lines can be constructed.
  • Faulting leads to formation of fault scarps where springs occur at the foot of fault scarps, attracting settlements.
  • Vertically faulting across a river may cause a waterfall which may be used to generate H.E.P

The above positive significance are among our list of 15 significance of faulting to human activities. Now let’s look at the negative significance of faulting.

Negative significance

  • Subsidence of the land due to faulting may lead to loss of lives as well as destruction of properties.
  • Faulting may change direction of rivers or even make them disappear. This may interfere with agriculture to farmers who depend on those rivers.
  • Faulting will result to uneven land surfaces as a result of faults, therefore disrupting transport and communication networks.
  • It may change the river direction hence causing floods downstream.
  • Fault lines are centres of earthquakes that may lead to loss of lives and destruction of properties.
  • It leads to formation of Horst mountains that receive low rainfall on leeward side, hence discourage agriculture.
