How can human activities affect the frequency and impact of natural disasters?

How does human activity negatively cause a natural disaster? The reason for the disaster is that human activity, be it incogitant deforestation or faulty levees system. If you can save vegetation by not cutting down trees and well-thought-out draining systems in settlements while placing dams correctly, then we can avoid so many tragedies.

It’s clear that we need to change course, or otherwise, disaster is inevitable. Humanity has been using increasingly harmful production and waste disposal methods as the population grows without any significant effort on our part to mitigate these issues through increased regulation. The situation will only get worse until it reaches a point where humanity can no longer sustain itself if nothing changes quickly.

Natural disasters caused by humans

Earthquakes: One of the most recent examples is the earthquake in China in 2008. The weight of all that water pushed on a crust fracture, causing it to collapse and create an even worse disaster than before.

Flooding: Hurricane Katrina was one of the most devastating natural disasters in recent history. A Category 5 hurricane, it swept through New Orleans and destroyed everything in its path. It took around 1,800 lives and caused over 100-million dollars worth of damage to homes alone as well as all infrastructure that Hurricane Katrina touched down onshore like levees, power lines, etc.

Dams:  Banqiao Dam in China collapsed under the pressure of heavy rainfall, claiming more than 171,000 lives.

Avalanches: The Philippines has witnessed the most disastrous avalanches or landslips in history. A rockslide leveled a mountain village Giunsaugon, killing thousands with its destructive force and taking away their livelihoods from them. The reason for it was uncontrolled mining and deforestation around the village that led to an avalanche at this location, claiming many lives

Landslides: On December 20th, 2015, a landslide in Shenzhen killed 70 people and destroyed 14 factory buildings. The reason for the event was an artificially made dump of the excavated soil with a height over 100 meters that caused heavy rainfall to bring it down.

FAQ’s

How human activity increases the risk from hazards?

As humans, we have the power to change hazards and create new ones. We can control our risk with engineering or engage in ill-conceived activities that jeopardize our environment leading to disaster.

How do development activities lead to disasters?

The geophysical setting with unplanned and inadequate developmental activity is a cause for increased losses during disasters. In the case of India, these factors contribute to high population density, which in turn leads to escalating loss estimates.

What is the main cause of natural disasters?

Natural disasters take place due to different reasons, including soil erosion and seismic activity. These natural occurrences occur in the earth’s crust and on its surface, which is what causes such events as tsunamis, earthquakes, and hurricanes.

What are the three effects of disaster?

In a disaster, you face the danger of physical injury or death. You may also lose your home and possessions. Such stressors place you at risk for physical health or emotional problems.
