“Understanding the Five Types of Earthquakes Triggered by Tectonic Plates | Bogordaily.net”

Bogordaily.net – Recognize the five types of earthquakes that are triggered by the movement of tectonic plates that can occur on the surface or in the earth.

During an earthquake, moving tectonic plates can cause cracks or faults in the ground.

This triggers other disasters such as landslides. Earthquakes can also occur at sea so there is a potential for a tsunami like what happened in Aceh in 2004.

Experts explained that earthquakes can occur suddenly with different intensities which are influenced by several factors. These include the epicenter, the condition and type of tectonic plates, as well as geological factors in the affected area.

To measure and detect earthquakes, a tool called a seismograph is used. This tool can also record the amplitude and frequency of earthquake vibrations. The seismograph itself was discovered by a British geologist named John Milne.

The following is an understanding of earthquakes according to their types:

1. Tectonic Earthquake

Earthquakes are triggered by the movement of tectonic plates, such as two plates separating from each other or colliding beneath the Earth’s surface. This earthquake can cause great damage in the affected area.

Local Tectonic Earthquake

An earthquake that is not felt by the surrounding community, but is detected by a seismograph. These earthquakes are usually triggered by tectonic activity in the earth. For example the movement of tectonic plates or the presence of faults in the lithosphere.

2. Volcanic Earthquake

Earthquakes caused by magma activity or before a volcano erupts. The higher the activity, it will cause an explosion triggering an earthquake.

3. Ruin Earthquake

Earthquakes that occur in limestone mountains or mining areas. It is local and rare.

4. Impact Earthquake

The vibrations occur due to the collision of asteroids or meteors that fall to earth. This is also a rare type of earthquake.

5. Artificial Earthquake

This earthquake was triggered by human activity. For example a hammer blow to the earth’s surface to a nuclear explosion or dynamite.

Earthquakes can also be categorized according to their depth, including:

• Shallow earthquakes The epicenter or hypocenter is less than 60 km from the earth’s surface and causes major damage
• The hypocenter medium earthquake is between 60 km – 300 km below the earth’s surface. This earthquake is more pronounced and can cause light to moderate damage.
• The earthquake was in a hypocenter more than 300 km below the earth’s surface. Because it is in the earth’s crust, these earthquakes are not too dangerous.

So that’s an explanation of the types of earthquakes and their causes. Stay alert!***
