One of the most harmful natural disasters on our planet is an earthquake. Reason for Earthquakes: They can strike quickly and wreak enormous damage in a matter of seconds, leaving a path of destruction, injuries to people, and property damage in their wake. It is vital to understand the causes of earth tremors. In this article, we will explore the Reason for Earthquakes, the different types of earthquakes, and the regions most prone to seismic activity.

The lithosphere is Earth’s outermost layer. The earth’s surface is composed of large, sturdy sections referred to as tectonic plates. They move a few centimeters each year compared to each other. Two plates can become stressed and stuck when they travel past one another. Eventually, the friction holding the plates together won’t be enough. They’ll slip and let go suddenly.

Reason of Earthquakes

What causes earthquakes?

The tectonic plates that make up the crust of the world, continually move. Friction can cause these plates to move more slowly as they collide in fault zones. Which can result in pressure building over increased periods. Sections of the crust suddenly crack or move as the force of movement ultimately exceeds resistance, releasing built-up pressure in the form of seismic waves. This is a tectonic earthquake, a type of naturally occurring quake.

Even though tectonic earthquakes can happen anywhere in the world. The bulk of significant earthquakes—about 80%—happen in the circum-Pacific seismic belt. Located on the Pacific Ocean’s rim. The Alpide belt runs across the Himalayan Mountains, Sumatra, Java, and the Mid-Atlantic Ridge. Runs along the bottom of the Atlantic Ocean, are two more areas that often experience quakes.

There are three types of plate bounds where earthquakes can occur:

  1. Convergent boundaries: These are areas where two plates are moving towards each other. When one plate is forced beneath another, a decreased zone is created. Rubbing occurs between these two plates and can cause earthquakes.
  2. Divergent boundaries: These are areas where two plates are moving away from each other. As a result, the plates move apart, magma rises from the mantle and cools to form a new crust. Earthquakes can occur as the plates move apart, causing the rocks to break.
  3. Transform boundaries: These are areas where two plates are sliding past each other. The friction between the two plates can cause earthquakes as they move against each other.

Other causes of earthquakes include volcanic activity, rockfall, and human activity such as mining and fracking. The causes mentioned earlier are relatively insignificant when compared to the movement of tectonic plates.

Types of Earthquakes:

There are two main types of earthquakes: tectonic earthquakes and non-tectonic earthquakes.

  1. Tectonic earthquakes: These occurrences are caused by the movement of tectonic plates. They are the most common type of earthquake and can occur at any point on the Earth’s surface. So, Earthquakes resulting from tectonic activity can be classified into three types based on their depth: shallow, intermediate, and deep.
  2. Non-tectonic earthquakes: Factors other than tectonic activity cause these, such as volcanic activity, landslides, and human activity. Tectonic earthquakes are more common than non-tectonic earthquakes. Compared to tectonic earthquakes, they are relatively rare.
Effect and Reason of Earthquakes

Does fracking cause earthquakes?

“Fracking” is a casual term for hydraulic fracturing, a process used to increase the flow of oil or gas to a production well. It entails the high-pressure injection of significant amounts of water, sand, and chemicals into bedrock; as a result, fractures stared in the rock or enlarge, extend, and link already-existing cracks, and rise permeability.

Occasionally, fracking can trigger earthquakes directly. Earthquakes are more often brought on by the dumping of oil production-related wastewater into underground wells. Seismic events linked with fracking and waste fluid getting rid of tend to be low-level and based on conditions such as the dose rate and total volume injected. the proximity of faults near the injection site and the pathways permitting pressure to travel from the injection site to the fault, and the presence of stresses on faults that are large enough to produce earthquakes.

Regions Prone to Earthquakes:

Earthquakes can occur anywhere on the Earth’s surface, but certain regions are more prone to seismic activity than others. The regions most prone to earthquakes are located along the boundaries of tectonic plates. These regions include:

  1. The Pacific Ring of Fire: This region encompasses the Pacific Ocean and is characterized by a chain of volcanoes and tectonic activity. The Pacific Ring of Fire is the most seismically active region on Earth, accounting for 90% of all earthquakes.
  2. The Mediterranean region: This region is prone to earthquakes due to the collision of the African and Eurasian plates. The Mediterranean region has a long history of destructive earthquakes, with several devastating earthquakes occurring in the past.
  3. The Himalayan region: This region is prone to earthquakes due to the collision of the Indian and Eurasian plates. The Himalayan region is known for its high-magnitude earthquakes above all other ranges, with several earthquakes of magnitude 8 or higher occurring in the past.


Finally, Earthquakes are a common occurrence that can result in extensive damage and fatalities for catastrophes to be predicted and prepared for in the future. The main reason for Earthquakes is the movement of tectonic plates, which occur in specific areas of the Earth.
