Earthquake Types

There are many types of earthquakes. In this article, we will discuss the most common types of earthquakes. Each type of earthquake behaves uniquely, so it is important to know what to expect to stay safe. We will also talk about some of the most destructive earthquakes in history and what caused them. Stay tuned for more information on earthquake types!

What is an Earthquake?

An earthquake is the ground shaking caused by the sudden energy release in the earth’s crust or upper mantle of the Earth. Earthquakes can differ in length from those that are so small that they are barely felt to those that are so powerful that they propel folks into the air, wreaking havoc on entire cities. The seismicity, or seismic activity, of an area, is the frequency, type and size of earthquakes experienced over a period of time. Seismometer measurements are used to measure earthquakes. For the whole globe, the moment magnitude is by far the most prevalent scale about which earthquakes bigger than roughly magnitude five are registered.

Earthquakes create seismic waves, which are vibrations that travel through the Earth’s interior or along its surface. There are two types of seismic waves: body waves and surface waves. Body waves travel through the interior of the Earth, while surface waves travel along the Earth’s surface. P-waves (primary) and S-waves (secondary) are the two types of body waves. Surface waves include Love waves and Rayleigh waves.

Types of Earthquake

There are four main types of earthquakes: tectonic, volcanic, collapse and explosion. Each type is caused by a different mechanism and results in a different type of shaking.

1.Tectonic Earthquake:

Tectonic earthquakes are caused by the movement of the Earth’s plates. The energy released during these earthquakes is incredibly powerful and can cause extensive damage.

Causes:

Tectonic earthquakes occur when the Earth’s plates move. This can happen when two plates collide, when one plate slides underneath another, or when a plate is forced to move by the movement of the mantle.

Effects:

Tectonic earthquakes are incredibly powerful and can cause extensive damage. They can also trigger other natural disasters, such as tsunamis and landslides.

2.Volcanic Earthquakes:

Volcanic earthquakes are caused by the movement of magma beneath the Earth’s surface. These earthquakes are often smaller than tectonic earthquakes, but they can still cause significant damage.

Causes:

Volcanic earthquakes occur when magma moves beneath the Earth’s surface. This can happen when the magma is forced up by the movement of the Earth’s plates, or when it is released from a volcano.

Effects:

Volcanic earthquakes can cause significant damage, even though they are typically smaller than tectonic earthquakes. They can also trigger other natural disasters, such as volcanic eruptions and landslides.

3.Collapse Earthquakes:

Collapse earthquakes occur when buildings or other structures collapse. These earthquakes are typically very small but can be deadly if they occur in a populated area.

Causes:

Collapse earthquakes occur when buildings or other structures collapse. This can happen due to a variety of reasons, including poor construction, severe weather, or an earthquake.

Effects:

Collapse earthquakes are typically very small but can be deadly if they occur in a populated area. They can also cause secondary disasters, such as fires and gas leaks.

4.Explosion Earthquakes:

Explosion earthquakes are caused by the detonation of explosives. These earthquakes are usually very small but can cause damage if they occur near populated areas.

Causes:

Explosion earthquakes are caused by the detonation of explosives. This can happen due to a variety of reasons, including mining, construction, or warfare.

Effects:

Explosion earthquakes are typically very small but can cause damage if they occur near populated areas. They can also cause secondary disasters, such as fires and gas leakages.

There can be other forms of earthquakes as well which include: aftershocks, foreshocks, and induced earthquakes. An aftershock is indeed a lesser earthquake that happens near the mainshock’s location after a larger one. A quake that occurs before such a stronger earthquake in the very same area is known as a foreshock. Human influence, such as mining, irrigation projects, and waste disposal, causes induced earthquakes.

Conclusion 

Earthquakes can be incredibly destructive and deadly natural disasters. It’s important to know the different types of earthquakes, what causes them, and how you can protect yourself in the event of an earthquake.
